Renu Energy Solutions

Very satisfied with my solar panel installation by Renu. They delivered what they promised on time. A project manager followed every step of the way to assure things were moving smoothly.

Technical Excellence and True Accountability

​I am writing this review to highly recommend Renu Energy Solutions based on their outstanding integrity, technical expertise, and dedication to customer satisfaction. ​Like many homeowners, I monitor my solar production closely and noticed some significant midday "clipping" where my system's output was being capped by the original microinverters. While this can be a common bottleneck in standard installations, I wanted my 395W panels to perform at their true engineered potential. ​When I brought my data-driven concerns to Renu, the leadership team—specifically Jay and Ben—stepped up personally to make it right. Instead of deflecting or offering a basic patch, they took total accountability and went above and beyond our original agreement to ensure I had a high-performance system. They upgraded all 14 of my microinverters to top-of-the-line Enphase IQ8HC units. ​Why Renu Energy Solutions earned my highest recommendation: ​Premium Hardware Upgrade: By upgrading the system to IQ8HC microinverters, they completely eliminated midday clipping. My 395W panels are now fully unlocked and delivering their maximum peak power potential. ​Integrity & Trust: It is rare to find a company today that prioritizes long-term customer relationships and system engineering over immediate hardware costs. They honored their word perfectly. ​Flawless Execution: The service team handled the physical installation seamlessly, successfully provisioned the new hardware in the Enphase gateway, and verified everything was tracking perfectly. ​If you are looking for a solar partner in the Carolinas who has the technical skill to build a great system and the integrity to stand behind it no matter what, Renu Energy Solutions is the clear choice. I am a very happy customer!

I just completed an installation of a solar/battery system with Renu Energy. I waited to write this review until my system was complete and I have received the 'Permission to Operate' from my Utility so I could comment on the whole process. From start to finish Renu was top notch and consistently met or exceeded expectations. Kevin Sweet, who made the initial sales call was superb. He provided a ton of concrete data and information and was knowledgable and informative. The information that he provided made it easy to decide how to proceed. Most importantly, I can now say that the numbers he provided and the timeline that he laid out has been proven accurate. Ryan Witt, the project manager provided excellent communication and clear timelines and guidance. Any question that I had was readily and rapidly answered. The installation team did a very good job and were professional and courteous. Among the various people at Renu that I have dealt with, I have always had the impression that they were communicating among themselves and were on the same page. I never had one person telling me one thing that was later contradicted by others. A+ for their teamwork. Overall, this is a very solid company to work with. They are installing complex systems - in my case the components come from at least three manufacturers. At the end of the day, It all works together in a compelling way. This team does what they say they will do and they do it professionally and in a time frame that matches what they quote. That is unusual these days. Thank you Renu.

Great Experience with Renew Energy

I recently had solar panels installed through Renew Energy, and so far I’ve been very happy with the experience. The entire process was smooth from start to finish, and the team was professional, responsive, and helpful throughout. Almir took the time to explain the system and answer my questions before I made my decision, which I appreciated. Ryan also did a great job keeping everything organized during the installation process and making sure things stayed on track. Since installation, the system has been running well, and I’ve really enjoyed learning more about how my home uses energy and how solar works throughout the day. It’s definitely been an adjustment learning the best ways to maximize efficiency, but overall I’m glad I made the investment. I appreciate the professionalism of the Renew Energy team and would recommend them to anyone considering going solar.

I’ve had my solar panels installed for a little while now with Renu Solar, and I’ve had a really positive experience so far. The system has been working exactly as expected, and I haven’t run into any issues since installation. One thing I didn’t expect is how much more aware I’ve become of my energy usage. It’s definitely a learning process, but once you start understanding how everything works, it gives you a lot more control over how and when you use electricity. The whole process from start to finish was smooth. Almir did a great job explaining everything upfront and helping me understand what to expect, which made me feel comfortable moving forward. During the project itself, Ryan was great to work with—professional, responsive, and made sure everything stayed on track. The installation team was efficient, and everything was completed without any issues. Since then, the system has been running reliably, and I’m looking forward to seeing the long-term benefits. Overall, I’m glad I made the decision to go solar and would definitely recommend Renew Solar to anyone considering it.

Headline: Ultimate Accountability – Renu Energy Solutions Exceeded All Expectations I am writing this review to share my experience with Renu Energy Solutions, specifically regarding their commitment to customer satisfaction and technical excellence. While our project initially encountered some technical hurdles regarding microinverter clipping and system design limits, the way this company handled the remediation process was nothing short of exemplary. Instead of offering a "quick fix" or a standard corporate response, the leadership team—specifically Jay and Ben—stepped in personally to find a real solution. They took the time to listen to my data-driven concerns and ultimately went above and beyond our original agreement. Key highlights of my experience: Technical Integrity: They upgraded my system to the top-tier Enphase IQ8HC microinverters. This high-capacity hardware has completely eliminated midday clipping, allowing my 395W panels to finally perform at their absolute peak potential. Accountability: Renu proved that they are a company that stands behind their word. Even when faced with a complex situation, they prioritized my long-term happiness and system performance over their own hardware costs. Professionalism: The communication from Jay and the team was transparent and respectful throughout the entire process. They held up their end of the deal and then some. It is rare today to find a company that views a challenge as an opportunity to build trust, but that is exactly what Renu did. I am now a very happy customer with a system that is performing better than promised. If you are looking for a solar partner in the Carolinas who you can trust to stand by their work and treat you with integrity, Renu Energy Solutions is the clear choice.

I had been trying to get solar panels installed at my house for years. I took the plunge last year when my county ran a promotion to get more homes set up with solar power systems. And I wanted to get my system installed while the tax credits were still in place Renu was the partner working with my county. They were thorough, professional, and unlike some other companies I'd reached out to, they were not in any way pushy. They thoroughly explained the process each step of the way. Financing was straightforward as well. They worked with me to build a system that will handle my needs today while also being able to handle future needs as well. The whole team were great to work with AND my panels were able to be installed weeks before I thought! My thanks to Ryan, Almir, and the whole team!

We recently had a solar roof system and Tesla Powerwall 3 battery installed on our home in the Charlotte, North Carolina area by Renu Energy Solutions, and the experience from start to finish was excellent. From the very beginning, Almir Hyseni, Area Sales Manager, was knowledgeable, transparent, and never pushy. He took the time to clearly explain the system, answer all of our questions, and set realistic expectations. Once the project moved into execution, Emily O’Hare, our Project Manager, did a fantastic job coordinating every phase of the project. Communication was consistent, clear, and proactive—there were no surprises, and we always knew what to expect next. The installation team Ben, Sofia, Marcus, Derek, Nate, and Dakota was truly exceptional. They were professional, courteous, and clearly took pride in their work. The crew showed great attention to detail and went above and beyond to protect our home and property throughout the installation process. The job site was kept clean and organized, and the work was completed efficiently without cutting corners. What really stood out was how well Renu communicated project timing and milestones the entire way. Every step was explained, schedules were honored, and any questions were answered promptly. That level of coordination and professionalism made what could have been a stressful project feel smooth and well managed. We couldn’t be happier with the final result and would highly recommend Renu Energy Solutions to anyone in the Charlotte area considering solar or battery storage. Their team delivers exactly what you hope for: great communication, skilled craftsmanship, and genuine respect for the customer’s home.

Finally found a reputable solar installer!!

I was stumped finding a reputable Solar installer because of the fraud common in that industry but somehow stumbled upon Renu Energy Solutions and as of a few days ago, my solar system is active with Tesla PowerWall 3. It's amazing! I'm so excited! I start charging with 8 panels when the sun comes up and my battery recharges to 100% by 11AM. The rest of the day with my 31 solar panels, I send back 5,000+ Watt hours back to the grid. 99% of my electricity needs I make myself with the panels. Renu staff and processes were as good as they can be. Sales people are knowledgeable, project managers are great and keep customers in formed and the technical installers did excellent work on the install. Most worry about holes in the roof but they use proven methods to attach the panels with equipment that itself seals the necessary holes into the shingles plus they insure against water damage. My next step is to ensure I only use all major items during sunlit hours so they're solar powered. I allocated a handful of items to be powered by the back up battery like the refrigerator, lighting garage door and the first floor HVAC so I'm covered during grid power outages at night. My install maxed out at just above $40K, minus the tax incentives it came to under $30K. Those incentives got canceled by this toxic administration but they'll be gone soon and incentives will return but indeed, the return on investment is well worth the cost.

Trustworthy Solar Company

We worked with Renu through a partnership with our town. We have a very old house with complicated roof lines and byzantine wiring. Renu was careful, thorough, and provided excellent service and clear, timely communications throughout the process. Their set up instructions were especially good, customized with photos of our house. We are grateful for their expertise and service and recommend them.

Renu was one of the most professional companies I have worked with. They kept me informed througho the whole process and did all the leg work with the City and HMO. Their installation team was very professional, and cleaned up after themselves. I would highly recommend Renu.

Since we already had solar panels in place , our main priority was battery backup storage. Renu's planners came to our home and gave us the information needed. We proceeded to go forward with this project and had a Franklin battery installed. All necessary permits were handled by Renu and their office kept us apprised of the progress relating to the final installation and any other documents regarding the backup battery. We are thrilled to now have a backup system in place in case of any emergency or power outage. The entire Renu team members were very professional and straightforward. Battery installation was smooth and the installers answered all of our questions. No regrets!

Had the system installed complete with a Tesla power wall and has significantly lowered my utility bills. The company was easy to deal with and followed through on on time lines and promises. Highly recommend them.

Great to work with

The entire Renu team has been amazing to work with. I originally had the install 17 solar panels, I later added a Tesla powerwall and I am now working with them to add additional panels and another power wall. They have very competitive prices and their overall instal quality is excellent. Additionally they are there to support you if you have any issues

Easy, seamless, and worked better than guaranteed!

An excellent, beginning to end experience with Renu Energy helping us consider, design, install, and trouble-shoot our home solar and battery solution. Every part of the entire process was extremely smooth, professional, and easy, including their bending over backwards to troubleshoot why one particular part of the installed system (one of the two batteries) didn't initially work. The designer patiently walked us through multiple sets of estimates and design proposals for all kinds of tradeoffs in terms of system size vs cost. They never pressured us to buy anything extra, but instead let us understand what every choice we could get added (and cost). The initial site inspection was simple and easy. They took care of the permitting, utility connection, and city inspection process seamlessly - all we had to do was sign stuff and let people in the house. The installation team was fast, polite, on time, cleaned up after themselves, and were careful with our home. When one of the two batteries didn't initially talk with the system, Renu coordinated successive series of Renu (and manufacturer) technical teams to come by and debug the system, ultimately coordinating a complete warranty replacement of the battery stacks. The system has worked flawlessly (including in blackouts) ever since, exactly as advertised. And after a full year, the system has produced nearly 30% more power than their guaranteed estimate and operated seamlessly through the Hurricane Helene blackout, allowing us to keep not just our house freezers and refrigerators going, but our neighbors', too. Overall, it was as easy and simple a process for a massive technical home improvement process as you can possibly imagine. I would absolutely recommend Renu to anyone who wants to install home solar. We picked them because we figured if they were good enough for Charlotte Motor Speedway and New Belgium Brewing, they'd do well for us and they did. Thanks, Renu!

Great job start to finish

They did a great job start to finish. Their bid was the most comprehensive and the lowest price. They took care of all the permits and started the install on schedule as promised. The installation was quick and they answered all my questions

Renu Energy solar with battery backup

Renu made the process of getting solar with battery backup so quick and easy. And with the rebate I got from Duke Energy ($9000), plus the refund I'll get on my taxes (probably close to another $9000), and the $53 credit on my bill every month from Duke for the PowerPair program, going solar was a no-brainer. The people at Renu were so friendly and easy to work with. I highly recommend.

Great battery installation

Great experience installing Enphase 5P solar batteries to my existing system. Excellent information, thorough permitting process, quick installation and communication. Went over and above keeping me in the loop throughout the entire process. Very professional.

Great Experience

The experience with Renu Energy Solutions was great from the sales presentation to the installation. They were great to work with and the project manager kept me informed and the install team did a great job.

Charlotte's Premier Solar Company!

Renu Energy did an amazing job installing solar panels, quick and quality work. Price is the best in space, and I did my research and out of all the quotes, like 10+. they beat everyone out. Moved quickly and went through all the processes and approvals fast, taking less than 4-weeks for the whole thing to be wrapped up and done! Highly recommend if you want a solid company with the best team to do your solar panel project.

Excellent from start to finish

Renu made the process of switching to solar so very easy. They were professional, knowledgeable, and helpful throughout the entire process. Installation was efficient and well constructed. Highly recommend.

Excellent company to work with

In 2017 I was exploring the possibility of adding solar panels to our house. I contacted Renu Energy Solutions because of their reputation. They were responsive, quick, friendly, and analytic in their approach. I needed some trees near the house taken down anyway, and they needed to come down if solar panels went up. I also needed a new roof. Renu bundled all three projects together to save me time, coordination, and money. Everything was handled professionally. The panels have not needed any work since. I enjoy the savings on my electric bill that the two sets of panels provide.

Highly Recommend!

Used RENU for my full solar system install and couldn’t be more satisfied with every person who helped through every single step of the process! Would highly recommend RENU Energy Solutions to anyone looking to go solar!

True professionals from start to finish

I was completely satisfied with Renu Energy Solutions. From the salesperson, the entire operations team and the crews who did the electrical and panel install, they were all professional, knowledgeable and extremely helpful every step of the way. I especially like the fact that they are all company employees, no outside contractors. Quality work, through and through. I highly recommend this company.

Great experience

Very happy with choosing Renu energy. They are very experienced and on top of my project. They took care of all the details.

Best Solar company by far

I shopped around with 5 different companies. Renee was the best in terms of covering questions, having the best materials and equipment and their pricing was great. The install went perfectly and we’ve been saving ever since. Highly recommend Renew Energy!

We had a good experience with the first visit with Cooper. Then the person who came out to look at the roof trusses was also good. Install crew very good too. Then it went downhill fast dealing with Calli. I was asked to sign the HOA application and I did. Then I get a call from the HOA for the $5000 security deposit. I gave them the check to start the process and save time. Then Calli said that I had to wait for the engineer packet for the county inspector to review. (Two weeks lost.) The inspector said he did not need to see it or go into the attic to inspect anything. I asked that the conduit from the soffit to the disconnect box needs to be covered. Calli said the inspector needs to see it. Wrong again. On Oct 19th got a text that the week of Nov 7 was the earliest opening to finish up. Well, that week came and gone - no calls. Then on the next date we had no one showed up or called again, I actually went out and spent $65 on needed materials to move this along. That didn't help so I covered the lower half section of the pipe waiting for someone to show up. Finally on Jan 25, 2023 the job was complete. So I will give everyone 5 stars except for Calli. Also we had to ask Calli 3 times to get the app for our phone to monitor the production and usage.

Outstanding Performance

Renu’s staff was outstanding from start to finish for our 42 (10kW) roof-top solar panels. Responsiveness and execution were excellent, including questions that I had following installation and connection to the grid. I fully recommend Renu to anyone considering a solar energy system.

Excellent Company, Employees and Experience

I am extremely happy with my experience with Renu. This is a fairly complicated project, and Renu made it easy from beginning to end. I started the process of purchasing solar and two Tesla PowerWalls in March of 2022, the 25 solar panels were installed over a two day period at the end of May, and we finally received approval from Duke to energize the solar system in early July. The PowerWalls were installed over one day in the beginning of October(there is quite a long wait time for those right now - that has nothing to do with Renu). The overall installation is clean and professional looking, and they listened to my questions and requests regarding routing of conduit and placement of equipment, and did everything possible to make me happy. They handled all of the permitting, inspections, and coordinations with Duke, while keeping me in the loop the entire time. The first thing that made Renu different was the sales process - they were not pushy. Instead of trying to push me into whatever configuration and loan they decided was right for me, they started by asking “What do you want to achieve with solar?” Every other installer I spoke with were mainly interested in throwing just enough panels on my roof to cover my current usage and getting me into a 25 year loan, and then maybe giving me more attic insulation, or a “free” Nest thermostat. I even had a salesperson tell me(regarding batteries) “oh you don’t want or need those, we’ll just put a natural gas generator next to your house, it will be cheaper and better”. Renu listened to me, geeked out with me, and then worked WITH me to design a system that does exactly what I want. They were extremely communicative through the entire process - their project managers are second to none in my opinion and other industries could take a lesson from them. I was in near constant contact via email and text message with their team over the entire 7 month process, and I enjoyed talking with them. Every employee I dealt with seemed to love their job and the field of renewable energy. From the sales people and project managers, to designers electricians and installers on the roof - every single person seemed to love what they do, and loved where they work - many of them had worked there for several years, which to me says something about the company. Also very important - they did not contract out any of the work to sub contractors - everyone I dealt with worked FOR Renu. Finally - the system itself works. I have not paid Duke for electricity since July 2022 - we produce roughly twice what we consume. Additionally, the two PowerWalls can power our home for over 24 hours, including air conditioning - on a sunny day they are fully charged by noon. Your experience may vary of course, but I can tell you that it can and does work! If you are considering going with solar, there are not many companies like Renu(trust me, I spoke with six others). Don’t waste your time or money talking to anyone else - you will be happy with Renu.
