Excellent Customer Service

Needed to replace a bad converter. Had difficulty getting the part from SolarEdge due to it being on backorder. Jared from Longhorn kept in contact with them and after a few weeks went by, instead of waiting any longer replaced it with a unit they had on hand. Installer showed up when promised, he was quick and professional. It was an all-around great experience. Thank you!

Greatly Lacking Customer Service

Very, very difficult to get in touch with a live person. Very confusing email traffic and MANY unanswered voicemails. Warranty is not a thing apparently, they came out on a warranty call and charged me for 2 hours when the guy was at my home LESS than 20 minutes! Then said it wasn't covered under warranty. THEN sent me a bill from another company for $329.88! AFTER I called and complained that the guy was NOT here 2 hours but 20 minutes! They argued that He had to drive here. Hmm, how else do you think he was going to get here? I am not paying him! he doesn't work for me! he works for you! Terrible company! The tech also showed up 2 hours late.

Great Solar Company

We were looking for a reputable company to install 15KW solar system along with 2 Powerwall 3's, and decided to go with Longhorn Solar after weeks of comparing options. Right off the bat, Jameson went above and beyond to explain the process, the design, and financing while being fully transparent unlike some other installers that we spoke with. Jameson was extremely professional and easy to work with and gave us full confidence that we were making the right choice. Once we made the deal, Fhilecya kept us fully informed on the permitting process and efficiently got everything ready to start the install within a month. The install crew was professional and respectful. However, there were some design changes they made I wasn't informed of due to roof air vent location, but Fhilecya and David quickly resolved the issue and addressed any concerns I had. David came back few days later for final inspection to bring the entire system online, and he was very helpful while explaining all the details of Powerwalls and solar system. Lastly, when I noticed few uneven panels and notified David, they sent the install crew back out the next day to fix the issue which was greatly appreciated. The system is working perfectly and producing much more than estimated on the proposal so far. I couldn't be happier how easy the entire process was and how Longhorn Solar handled everything, will definitely be recommending them to neighbors and coming back to them for any future services

No real interest in providing quality service

Extremely poor quality work and supervision. Subcontracting out work to inferior and inept contractors. Would not return phone calls for service / warranty request. Keeps contacting me offering a reward to help them find new customers - like I'm going to do that based on how I have been treated and the poor quality of work they performed.

Mike | Whitney, TX | 02/06/2024

Solar System Satisfaction

Selected Longhorn Solar because of their detailed sales presentation and initial design. Guided us through selection of equipment / configuration options giving us the detailed pros & cons of each. Wanted to deal with an experienced supplier/installer rather than a broker. Looking for that one accountable company. We got a detailed design, a performance warranty and Longhorn Solar handled all permitting both through CoOp and HOA. System was installed in 29 days less than originally estimated and has been working flawlessly since commissioned in January. Price was competitive, communication was solid. Crews showed up when promised and did a great job of cleaning up debris. Hopefully after sales support will be the same great experience.

DM | Austin, TX | 01/30/2024

They should hire me for project management because I did a lot of the coordination work (they should be doing this!) on the solar project at my home. Frustrating when no one at Longhorn calls back nor emails back (this happens frequently. I eventually get responses but it's because of my constant follow-ups), an appointment resulting in a no show from their tech person, an old part (trash) disposed on my property grounds, technical issue that took awhile to get resolved, etc. All the problems have been post sales installation and post sales service. The best part of the process was the sales. In fact, Longhorn Solar’s salesperson Ron Martin is outstanding. This recommendation is strictly in regards to Ron Martin who demonstrated solar knowledge expertise and excellent customer service … many times above and beyond. He’s friendly and returns calls. Sometimes when a salesperson completes their sale, one never hears back. But Ron has always been reliable in getting answers for me, even after the purchase was made. He has also visited my home to further explain the solar system and walk me through the apps. I recommend Ron Martin wholeheartedly.

David | Austin, TX | 08/30/2023

Poor customer service

We got our 12kw system about 10 years ago. The first couple of years, they called me regularly to make sure everything was running well. A year ago, I noticed one of my inverters was showing zero amperage. I called to report it. About 2 months later someone finally called, saying they’d check it out and let me know. I never heard back. I’ve called 6-7 more times, and no one calls me back. I called again 5 days ago. A woman called 2 days later saying someone would call me in 48 hours. I’m still waiting! Unacceptable.

Great Install and Even Cleans Up Other Companies' Messes

Longhorn did my initial install in March of 2021 and I have had absolutely no complaints about their work or my solar production. I had one issue with a panel in late 2022 and they sent a tech around to check on it and fix it without any additional cost. Then this past June, SolarEdge, the mfr of my inverter, contacted me letting me know they were shipping a new inverter because there was an issue and it needed to be replaced. An appointment would get made with Longhorn to do the swap. However, SolarEdge contracted with Sunnova instead of my installer to do the work. The guy was barely understandable but told me they didn't have a cellular card to put in the new unit and said he would get one and be back out in a couple of days to install it. I never saw that guy again. After communicating with Sunnova and SolarEdge on several occasions about this issue, it was clear they weren't interested in making it right. So I contacted Longhorn and they made some calls and were able to get SolarEdge to send a new card; as soon as it arrived, Longhorn was at my house doing what Sunnova wouldn't do. All for free. Thank you Jeffrey Jones and Matt S. for all the help and friendly service!

Patricia Mills | Round Top, TX | 07/24/2023

Maintenance

This company’s response to problems with their equipment is terrible-no response to email/texts. 2 weeks of contacts before a real person responds. Our inverters have stopped working at least 3 times since installation.

The Rail Guy | San Marcos, TX | 05/17/2023

Jameson Dillon, Sales Manager

My experience Jameson & Longhorn Solar Inc. was great. I would recommend Longhorn Solar to others. I am more than satisfied with there performance and cooperation. I originally had a 42 panel system installed with out batteries in 2017 (based on 80% average usage). Problem was when the grid goes down the panels are useless. System upgrade: Longhorn Solar installed a TESLA (2)battery system last fall and then 8 additional panels this spring. Love the system and on most sunny days I am able to operate 100% self powered! Wow...

10 percent won't buy you time of day

I signed my contract with Longhorn Solar at the end of August 2021. Here it is September 27, 2022 and my system is yet to be installed where it will pass even a simple test of turning off the Grid power and seeing how long we can live on our Sonnen EcoLynx20 battery. Test FAILED at one hour and it powered down the whole house with 86% battery charge showing remaining. Attempted to address this issue with Sonnen, whatever changes they made powered down the battery completely. I was told I could power the battery back up and all should be well. Not a chance, battery will not power up, we are dead in the water as far as battery backup goes. Sonnen said that given it would not power up I needed to talk with my installer to remedy the situation. I contacted them over 10 business days ago and copied in everyone I had an email address for and all I have heard is crickets. Today we heard reports that thousands of folks in Austin are without power, luckily not us, however my wife heard that story and she is not at all happy and called Longhorn today to receive a message that the tech support folks had forgotten that we were down. If you decide to go with this company demand a 40% 30% 30% payment schedule, holding 10% of their final payment is not enough to even get the time of day from them with their standard 20 40 30 10% schedule. So as it stands now they have 90% of my money and I have no battery backup, no solar feeding into the system when the Grid power is turned Off and a very unhappy wife. I'm not very happy either and today my patience has ended also.

Could have been worse, but that's the best I can say

I would love to leave Longhorn a good review, but unfortunately I just can’t. The sales process was clear and smooth, but installation was, frankly, a nightmare. I’ve had many companies work on my house, and Longhorn is by far the least responsive and least reliable company I’ve worked with. I regret selecting them, especially since I’ll need to rely on them to service the system in the future too. I should have canceled my contract at the first sign of trouble. Don’t make my mistake. My install date was pushed back multiple times over two and a half months with little to no communication. I didn’t even know our late May date was canceled until no one showed up on the day the project was scheduled to start, even though I’d called and emailed my project manager multiple times that week to confirm it (she never returned my calls or emails). When installation was finally set to begin, there were issues immediately. Despite claiming they only use in-house teams, a subcontracted company installed my panels. The battery team from Longhorn and the subcontracted panel team were not on the same page, and in fact didn’t even know about each other at first. It took over a month and a half from the panels and batteries beginning installation to finally being completed. During that time, my voicemails and emails were almost never returned. I learned that I had to catch someone in the office if I wanted a response, but that I had to call outside of their daily morning multi-hour all hands meeting, where no one in the office is accessible at all. Even when I was rarely able to catch my project manager on the phone, she was almost never able to tell me anything other than that she’d ask her manager at the next day’s all hands meeting and call me back. Which, of course, regularly didn’t actually happen. When someone would finally be scheduled to come finish installation, usually 1-2 weeks out if I was lucky, they often failed to show up at all or didn’t send enough people to complete the work, meaning things would be pushed out another week or more just to get another appointment scheduled. It took over 3 weeks (and multiple missed or canceled appointments) just to get someone to come back out to commission the batteries when the panels were finally done. When my system failed the QC inspection, I almost cried out of frustration knowing it would take weeks and dozens of calls to get things fixed (which it did). I spent hours every week just trying to reach someone and get on their schedule. Fortunately, Danny became involved in the project towards the end. While he wasn’t able to single-handedly fix all of the issues Longhorn has and things haven’t been smooth even with his help, it was refreshing to be able to reach someone reliably and to be in contact with someone with the ability to get things rolling. I appreciate his efforts. I can’t imagine how much longer my project would have taken to finish without his help. When installation was finally complete, I was told someone would walk me through my system and that I’d receive an owner’s manual. It’s now been over two months and despite several requests, I haven’t received either of these things. With all of these issues, I’ve received a few vague apologies but no other efforts to make things right. As a business owner myself, if a customer had experienced all the issues I had, they’d be looking at a hefty discount at a minimum. Unfortunately, one of my batteries is already broken. It took over a month from reporting the issue to get someone out to work on it, and now a new battery has to be ordered, which will take at least another month. I understand that Longhorn has staffing issues currently. I would hope that a responsible company would adjust their project schedule to only take on the work that they can handle, but it feels to me that Longhorn’s goal is profit first, customer satisfaction dead last. I hired Longhorn for my project despite them being one of the higher quotes I received due to their formerly excellent reputation. I wish I’d gotten what I paid for.

Broken inverter 2 times in 3 months, system still down

Terrible experience with longhorn solar, got an inverter broken 2 times in 3 months. System still down. Total uptime for the system is not even 75% a year, which pretty much renders a 16kw battery useless. When offered them to amend to contract to account for their lack of support/warranty, they rejected it. Worst investment was not solar, when it works is great, worst investment was picking longhorn solar as the installer. Just stay away. Remember, my system is still broken. It was a $37,000 system paid in full in cash. But they don't care about that since I already paid. They claim there are logistics problems, with supply chain issues. However they continue to install new systems while mine is down. So it is not about a supply chain, but about priorities. Again, just stay away from them.

Leo | Plano, TX | 05/19/2022

Do not honor warranty

Update: Installer corrected the problem by installing a new inverter, 26 days after reported. I paid a system in full with longhorn solar, the system did not last 1 year, a broken inverter. Longhorn keeps claiming chain supply issues while still getting new businesses, but not repairing mine. Their support system is basically none, one email contact that might or might not reply you in 3 days if you are lucky, and never gives a clear answer. I have a dead system, including a 16kw battery. Lesson learned, Look somewhere else, and force them to put a specific repair time window in your contracts.

TOO LONG INSTALLATION | San Antonio, TX | 03/31/2022

7 month installation and still not complete

Longhorn Solar Inc., services San Antonio out of Austin. Signed contract in Aug 2021, panels installed Dec 31,2021 but not hooked up and today is March 31,2022. Lame excuses all over the place as to why the delay. My advice is use company with service people in your city, not serviced remotely. My probable guess is Longhorn has only have 1 certified electrician to service San Antonio, traveling out of Austin. They have missed promised appointments without a phone call . When I call to ask why not showing up? Admin girl says she does not know why and resets. Here is one example of miscue: The onsite certification inspection meeting, final step before solar meter is installed, with CPS, failed because paperwork did not have an stamp. Inspector stated he would lose his job if he approved install without the stamp on documents. Seems like Longhorn is cutting corners. Inspector found other issues and was kind enough to help new electrician know what was missing. I am now glad someone is reviewing Longhorns work because I do not know the codes; 3 weeks later and still no resolution only missed another scheduled meeting.

Eric | Elgin, TX | 03/12/2022

Professional and Thorough

I was hesitant about getting solar installed from the horror stories I’ve heard. Well I have to say there is a reason Longhorn Solar has been around for as long as they have. They didn’t try up sale me on a system I didn’t need were very thorough every step of the way. Even when through no fault of there own when weather conditions prevented them from installing my system on the scheduled date. They made up for it by coming out the next day with double the crew to install the system. Now I am looking forward to geeking out with monitoring system and watching my system safe me money. Also continued work with Longhorn Solar in the years to come.

Forthright Solar Installer

Longhorn Solar is a local company committed to customer satisfaction rather than growing larger. The sales rep knew her stuff. The original proposal was scaled to our current electric consumption. After we checked out some reviews, people said they wished they had purchased a system to accommodate increased energy needs over time. The Longhorn rep put together a new proposal to cover 120% of our current usage. I am glad we went with the larger system and battery. Everyone we interacted with at Longhorn was trustworthy, professional and personable. It's a process. Things don't always go as planned, but Longhorn kept their promises. The service, expertise, quality and value are there. I would highly recommend Kathie Millen and her team to set you up with the right solar system.

MB | Austin, TX | 02/23/2022

Super helpful to new owners!

We purchased a home a year ago that had panels installed by Longhorn Solar - but we knew very little about whether they were working as they should or what maintenance they might need. We reached out to Longhorn and talked with Jameson, who responded really promptly to my inquiry. He was able to view our panel's performance remotely, and let us know that there were a few components that needed some repair/optimization. (It is an 8 year old system.) Then he informed us that the repairs would be covered under the warranty, which was a big surprise, as warranties don't always transfer to new owners. We are really happy to have panels installed by a company that stands by their equipment and installation no matter who owns the property - and were really grateful for Jameson's excellent customer service!

Jack | Anna, TX | 02/18/2022

Great Folks - Ethical and Dependable

Longhorn Solar is an ethical and dependable company and they provide results. They listen and do not over-sell their products. They truly have their customer's best interest in mind !

Michael Bland | Round Rock, TX | 02/09/2022

Overall very happy with Jameson and the installation crew

Dorlisa | Jarrell, TX | 08/07/2021

Easy process and amazing install crew!

I live in Jarrell and Longhorn solar just installed panels on my home. The process was quick and easy and the installation team was very proficient and friendly! Would highly recommend them!

Martinez78261 | San Antonio, TX | 07/05/2021

System down 6+ weeks

My system has been down for over 6 weeks. Whatever they tell you, they don't monitor your system for you. I left multiple messages on their service line, over a week, all were ignored. Finally got a hold of someone in person and scheduled a service date (no mention of the previous messages they failed to return). The first available service date they gave me was in three weeks. Three weeks! Three weeks longer to wait until someone can even come out and look at my system. I'm really disappointed in Longhorn solar for misleading me in terms of how they "monitor" my system as well as an utterly unresponsive service team.

Our review of Longhorn Solar | Elgin, TX | 05/28/2021

Update, 14 months of using our Solar Panel System

Longhorn Solar sized & installed our Solar System 14 months ago. The system is producing per original objective. It is really gratifying that we have not had to pay an electric utility bill over the last several months having accumulated so many credits with our electric provider. We suffered hail damage on our roof during the first quarter of this year. Our panels, all mounted on the carport, were not damaged and continue to produce. Bottom line, we are very happy with the system Longhorn Solar installed for us.

A Very Satisfied Continuing Cust | Austin , TX | 04/28/2021

Longhorn Solar is Exceptional!

I decided to write this review because when my husband and I decided to invest in solar panels for our home is was difficult to determine which solar company to use. We met with a group of ten interested neighbors and after studying the reviews and talking with numerous solar company representatives we all voted to go with Longhorn Solar. That was in 2015. Longhorn did an exceptional job for all of us. Everyone was highly satisfied. I am submitting this review now to inform anyone who is thinking about purchasing solar panels that Longhorn Solar not only was the right choice 6 years ago but Longhorn continues to be the right choice today. The Critter Guard under our solar panels came loose and I decided to call Longhorn's customer service to find out how I should go about getting it repaired. James sent out one of their installers to take a look at the problem and then he called us to say that Longhorn would reinstall it at no cost. Once again Longhorn Solar exceeded our expectations. Longhorn Solar is truly a company that stays committed to its customers. I recommend Longhorn Solar to everyone and anyone wholeheartedly!

Wayne | Coppell, TX | 04/14/2021

Solar panels plus battery backup.

We’ve had our system since June of 2020, and we are very pleased. Part of the system included a backup battery that covered about 8 circuits in the house. During the freeze, we were able to keep warm using electric blankets that ran off the battery, even though the panels were covered in snow. Every time the power cycled on during the rotating blackouts, the battery would recharge. That was an unexpected bonus.

Tony F | San Antonio, TX | 02/03/2021

Happy so far

So, when I decided to install solar for my home in San Antonio, I did some research and contacted about 10 different companies. All were recommended by CPS, the local energy company; all had very nice ratings. I considered one that offered panels made locally, because I wanted to shop local, but then discovered a shaky financial past. The others offered similar panels, and competitive prices. I discarded a company because their rep showed up at my house and didn't bring a mask. We met in the garage with the door rolled up (very warm in June). I downgraded another company whose rep crunched some numbers, then suggested I double the panels his formulas recommended. I went with Longhorn because their proposal was relatively easy to understand; we chatted via Zoom, and their rep sent me his presentation (only company that did that). This made it easier for me to review what was offered, to analyze the numbers. I really appreciated the Zoom meeting, as I am immuno compromised. Finally, the deal closer was the production guarantee. They calculated what the panels should produce in a year, and guaranteed to reimburse me if energy production didn't meet their proposal. The only "gotcha" was in activating the system. After a couple of weeks, I asked when the system would be initialized. I was told they were waiting for the city to schedule an inspection. A week later, I tried again, with the same response. So I called the city and explained my situation; they scheduled the inspection for the next afternoon. Can't figure why this happened, as the final payment was due when the city approved the system. But, the city came, blessed the panels, and I've been saving on electricity ever since.If you're looking for solar, these guys are worth a good look.

Great Service!

If you are looking for a professional, efficient team to provide your solar installation, Longhorn Solar is the way to go. They provided step-by-step updates of the installation. Afterward, they promptly schedule check-ins to ensure your system is running smoothly. Overall, it's been a great experience.

Yunny | AUSTIN, TX | 01/08/2021

We have the best solar service ever!

We have been big fans of Longhorn Solar since the very beginning. When we first started this process, we had gotten a few bids for our potential system and Longhorn had the lowest bid out of any of the other companies. Of course the other bidders were willing to match Longhorn's pricing, but I appreciated that Longhorn gave us the most competitive pricing from the get-go. Even though we have had our panels for 4 years, we continue to get the absolute best service from them - they follow up on our system and check in every so often to make sure we are still happy with out system. It's been a great experience and a lot of our neighbors have also used them for their service, dependability and fair pricing.

Mike R | Anna, TX | 01/01/2021

Great Company, Professional Team, no more electric bills

Louis and his team were great to work with. I looked at every solar company in the area and Longhorn Solar provided the most comprehensive bid and put the most effort into determining the best option for our needs. Getting Solar is a no-brainer. We became a net-zero household thanks to Green Mountain Energy's net metering program, are banking the former monthly electric bill and government incentive, refinanced using a Home Energy Loan and our mortgage payment stayed the same while paying for the Solar Energy System. In addition to feeling like we are doing the right thing, we improved our finances in the process.

Maureen Meredith | Austin, TX | 12/30/2020

Very Thorough and Responsive

I’ve had my panels for about 5-6 years. Over this time the entire Longhorn Solar staff has been proactive and helpful. I highly recommend them for people interested in solar panels in their homes.

Kam Knab | Austin, TX | 12/30/2020

Great! Easy from start to finish and the SAVINGS are excellent!`

I had a wonderful experience with Longhorn Solar. They did a great job educating me about their services and product and were not pushy at all (unlike the other solar providers I talked to). They have a personal point of contact for the whole project that helped me and promptly responded to my questions. They handled all the paper work and even the AustinEnergy rebate process. Installation was quicker than expected and my results are great! I haven't had an electric bill in months. I would highly rate Longhorn Solar and their East Austin team led by James K.

Rene | Austin, TX | 12/30/2020

Excellent company, no reservations

We chose Longhorn Solar and are quite happy with our choice. The customer service has been great and everything was done in an efficient manner. They also do a good job and reaching out over the years to ensure that everything is working at an optimal level. All of the staff members and just recently James have all been kind and helpful. We never felt like they have been pushy, they seem genuine to want to provide a good service. I highly recommend Longhorn Solar.

Kirra | Manor, TX | 11/28/2020

Great customer service

Longhorn treated me great throughout the entire process, answered any questions I had at anytime without making me feel like I was asking too many questions or dumb questions. My account manager, James, has been great and makes me feel like part of the Longhorn family! The install team was very nice, professional and efficient. I would recommend Longhorn any day of the week!

Miguel De la Torre | 11/24/2020

Good product overall

Solar panel privation is very good, had some problems with Solar Edge system that was finally fixed.

Dan Carlson | Pflugerville, TX | 11/02/2020

Bryan Kerr / Longhorn were great!

I spoke with a handful of solar companies before deciding on Longhorn. I worked with Bryan Kerr who was GREAT. He was super helpful, knowledgeable, and had great communication. We talked many times throughout the whole process, he always kept me informed and up to date on things. I would ask a question and he would be able to answer it in a simple straightforward way that was easy to understand. I chose Longhorn after they were recommended to me by my neighbor (now a few neighbors have chosen Longhorn). Longhorn prices were the best, much better than their competitors. Their app is great, it shows me all the panels and how much they are producing throughout the day so I can always see what's going on and how they're doing. And the team was great, they got all 23 of our panels finished in one single day. All in all, great experience, highly recommend. Longhorn is, as far as I know, the best solar company in the Austin / Pflugerville Texas area!

John | 10/28/2020

Professionalism at its best

The Longhorn solar team were kind, courteous, professional, informative, and did not try to sell me something I did not want. The tools they used to help size my project made it very easy for me to understand. They handheld my documentation through my homeowners association and I had nothing to do. They assigned an amazing project manager that kept me informed of my installation through every step.

Jameson Dillon is a wonderful representative for Longhorn Solar.

After hearing a suggestion about Longhorn Solar, then speaking with Jameson Dillon (Longhorn's Representative), the comfort level that I needed to proceed with our solar choice was met.

Excellent service, a great product, and on time! Excellent team

A friendly company comprised of great people. All products and services delivered on time, in good order, with great service. It’s worth it to get a buy a better product from a reputable company. Would purchase again from them.

No Calls Back

I purchase a home that has a warranty for ten years service. I continue to get an error on my machine for Solar and wanted to have someone come over for maintenance to see if is working correctly. My bill with CPS have been from $225 to $250. We are only a family of 4 at home. It took me 3 months to get someone on the phone after leaving several messages too. Finally, the following week someone came over to see but he didn’t have all the answers. Tim told me he reset my Solar because of the error. He was going to double check on things and get back to me the next day. It’s been 2 weeks and nothing from that guy. He told me I might have to upgrade for more panels. Okay, so my panels are not working and you are worry about selling me more of the panels. Don’t purchase from this company because they will not try to fix the problem.

Good Job

We got our panels installed less than a week ago and our system is already up and running. Bryan did a great job explaining the numbers and financing. They did reschedule our install last minute, so it’s important to keep in mind stuff like that can come up. Kelli did an amazing job keep us informed and getting us all the paperwork. She even basically handled the HOA stuff! She was awesome. The install crew was on time, quick, and courteous. Overall a pretty good job.

A thoroughly happy customer!

Longhorn Solar is a locally owned business. They've installed many residential systems. They were willing to work with me even though I only needed a minimum size system. Other companies I contacted wouldn't even call me back when I sent them a photo of my electric bill. I had to get my contract submitted to Austin Energy within 24 hours so I would qualify for the $2500 incentive and the extra $1000. Jameson Dillon got it done, even though the deadline was on a Saturday. The crew showed up on time about a month later and installed the system. They did not hurt the roof or my new gutters. There have been several bouts of severe weather since then, but my solar panels are fine and well secured. I had to wait another month for Austin Energy to show up and inspect the system, but everything passed muster and they turned on my system. Since then, I have not had to pay an electric bill. Through May, 2020, the value of solar production exceeded the cost of the electricity I used, resulting in a credit which stays on my bill. In June and July, I owed small amounts for electricity, less than $20, but the credit balance I had built up covered those. In comparison with the same months in the year before I got solar, I have significant savings every month, such that my system will have paid for itself in less than ten years. I had been interested in solar for years, and I'm very glad I finally took the plunge. I had my rebate and $1000 extra incentive from Austin Energy less than three weeks from when Austin Energy inspected my system and turned it on. Longhorn Solar handled everything with Austin Energy. I can't recommend them enough! Longhorn Solar is definitely the company to choose for solar in Austin.

Terrific experience, start to finish!

I talked with several different solar companies in my quest to go solar and from the first conversation, Longhorn Solar stood out. The sales rep, Mike, was professional, knowledgeable, and kept my budget and concerns in mind from the start. There were no high pressure sales tactics or things of that nature; Mike wanted what was best for me. Throughout the process, Longhorn was quick to respond to any questions I had, and did a great job working with my HOA. The install crew was fast and efficient, and completed the install in just a few hours. They even painted the conduit the same colors as the siding on my house! Aside from being great to work with, Longhorn also has the most competitive prices, which certainly helped! All in all, I’m thoroughly satisfied with Longhorn Solar, and highly recommend them.

Phenomenal customer service!

Longhorn Solar was everything I could have hoped for!

Thinking about buying solar for my house, I contacted Longhorn Solar and several other companies.  Within 30 minutes, the salesman, Mike was in touch with me. Some of the other companies took days.    Mike turned out to be extremely knowledgeable about solar installations and was very professional.  The conversation did not feel like he was trying to sell me something, more like just talking about solar panels and what kind of installation would work on my house, unlike other companies with high pressure and sales people that really didn't know much about solar.  After Mike left the house that night, my wife and I knew Longhorn Solar was who we wanted to go with. Being an amature radio operator, I have highly sensitive radio receivers in my house.  After signing the deal with Mike, I found out that solar panels are known for producing localized radio frequency interference within the amature radio frequency spectrum which would not be good for me!  I contacted Mike and expressed my concerns.  Mike contacted SolarEdge, the company that makes the solar panels they use.  SolarEdge was aware of this problem and had designed a special DC optimizer that would not cause RF interferance on the amature bands.  When installation day came, SolarEdge flew an expert in radio frequency interference from California to my house in Texas to make sure the system was installed in a way to eliminate any stray RF.  I was amazed a company would go to these lengths, after the sale had been completed, to make sure they built a system that would meet my needs. I think the fact Longhorn installed the more expensive special DC optimizers and SolarEdge went to the trouble to fly someone out here from California at no extra cost to me speaks volumes to the fact Longhorn AND SolarEdge will do whatever it takes to satisfy you, whatever your needs are.  When I expressed my amazement to Mike about all of this, he just said "That's the way we roll Vic". I highly recommend Longhorn Solar and SolarEdge solar panels.  Since the panels have been installed, my power bill has disappeared and we feel good knowing we are doing our part to reduce carbon emissions.

Excellent customer service

We chose Longhorn because they had superior equipment, good pricing, and a low-pressure sales approach. They chose a different arrangement on our roof than other folks suggested, allowing us to get more panels in the available space. They've provided excellent customer service over the years and usually reach out annually to see how things are going and if we need anything else. Absolutely no problems with the system two years in.

John Edgar | Bastrop, TX | 07/21/2020

Longhorn exceeded expectations

I was nervous of the process before I started. Jameson was knowledgeable and able to communicate in simple terms the important information. Install was quick and clean and system is performing as well and better than what was expected based on original estimate.

Satya | Plano, TX | 07/18/2020

fedup with no response and they don't know how to fix issues

they installed my plant about 4 years ago and for the last one year, my system is getting ground fault errors constantly every week. Sometimes 20 times a day. I probably reached out to them about 100 times. Its like blackhole with no response. Couple of times they responded and actually sent someone to look at it. But they could not figure out what is going on.

CatTrick Forest | Paige, TX | 07/15/2020

Quality components and staff

We chose this company because we were more impressed with their presentation and their flexibility with their equipment and projections than another company we interviewed. Longhorn Solar followed through with what we asked for and if something wasn't up to par, they acted. We would use them again if we ever move and need to install solar again.

Omar Cruz | Austin, TX | 07/11/2020

Longhorn solar is GREAT!

I was very skeptical about this solar stuff and always getting telemarketing calls about it being free. I contracted Longhorn solar and started working with Jameson, and he was great! I never felt pressured like as if he was salesman, he worked with me and explained all my options and different panels I could use to stay within goals for my house and price range. I've now had my panels for just under 2 months and WOW. My electric bill has gone down more than half! Even now that I work from home and use more electricity through out the day my electric bill is still 1/3 the price it use to be. This was definitely worth the investment.

Henry | Mesquite, TX | 05/30/2020

Bad Installation

They promised many thing to sell the system even the owner stated that they would respond quickly. Well only thing they responded is to money that was it. They did horrible job with installation to praises by Jeremy come to find out he did not care they did installation wrong they did not install the sleeves they just bolted the panels to the roof and the wires are touching roof. I contacted about the issues only thing I get from them is good luck. They sent tech outs because they covered a vent on roof and they are refusing to fix it. They also on install hit the vent for stove and leaked which required replacement of duct and repairing vent on roof. When contacted them they did not care. They drilled in to bricks and siding which basically damaged the items and they gave excuses. So basically they just did what they needed to in order to get money and they do not offer any assistance in fixing issues. They sent tech out and they were supposed to come back this week they no showed and no call. They will not send me a receipt for total cost but they already billed everything out. This is the worst company I have ever dealt with excuse was they closed the Dallas and San Antonio office because of issues if that was the case you would figure they would resolve the issue but no such luck. I would not recommend this company to my worst enemy.

About Longhorn Solar, Inc.


Longhorn Solar Mission: To make solar accessible to anyone who desires it by providing the best products at the best prices and installation by the most qualified TEAM that exists.

We achieve this mission by:

1. Doing extensive research on the products that we provide to give you the peace of mind that you are only seeing products with a Tier 1 rating and have been vetted for bank-ability. Bank-ability is important because a warranty from a company that is out of business is worth nothing.

2. Using our buying power to get the best price for the best production. There are some panels out there that claim to be a better product because of higher efficiency. Higher efficiency does not equal better. It equals more expensive. In the end, higher efficiency means they produce more electricity in a smaller space for a higher price. To make solar more accessible we have chosen slightly lower efficiency for a lower price.

3. Employing the highest trained staff in Texas. Longhorn Solar invests in training at every level. Currently, we employ several team members who hold NABCEP Solar certification in Texas. We are also one of the only companies to provide a 12 week training class for all of our new Account Managers. When you speak to a Longhorn Solar Account Manager, then you can rest assured that we know what we are talking about. We would be honored with the opportunity to provide you with a Solar System quote and then installation.
