Disappointed :-(
Extremely disappointed with Renu Solar and its customer service We purchased our solar system from Renu Solar in 2020 for approximately $40,000, and we paid the system off this year. The system had been working well until the inverter stopped working more than a month ago. Since then, our electric bill has nearly tripled. We immediately contacted Renu Solar and were told that it would take approximately a week to obtain a replacement inverter, after which service would be scheduled. Three weeks passed with no update. We finally contacted Sun Service, the company Renu contracts with to handle these repairs. We were told that the replacement inverter had not yet arrived. Because we were getting nowhere, I asked to speak with a manager. When the manager finally returned my call, I was told that, amazingly, the replacement part had suddenly arrived at their office. However, I was then told that they could not schedule the repair until their service team had other repairs in our area. Another week has now passed. I also contacted Renu’s corporate office directly, yet the only communication we have received is a text message saying that we are still not scheduled. This is extremely disappointing. We spent a lot on this solar system, have now paid it off, and reasonably expect the company to stand behind the system and provide timely service when a major component fails. Instead we have a non functioning system and are being held hostage by a contracted repair company Sum Service - Renu needs to do better. Renu Solar promotes itself as a solar company that has remained in business while other solar companies have closed. Staying in business is not enough, though. Customers also deserve responsive communication and reasonable service when something goes wrong. More than a month without a functioning inverter, with our electric bill nearly tripling, and still no scheduled repair is unacceptable to us. Based on this experience, I cannot recommend Renu Solar

Frustrating experience with a lack of follow through
Communicating with Renu is exceptionally challenging. Every employee I interacted with aside from sales was difficult to contact and didn’t follow up. The design of my solar installation went poorly. I raised issues. They ignored them. My system was undersized because they took poor measurements. They promised to help correct it, but they have failed to do so after 8 months. Additionally, they pulled me into a payment dispute with one of their subcontractors. That refused to pay them and I have a lien on my home as a result. After months of asking them to resolve it, they haven’t.

My experience has been very disappointing.
I began the process of expanding my solar system nearly a year ago. During that time, I was sold equipment that I did not actually need, which resulted in unnecessary expenses and wasted time. As someone who trusted their expertise, I expected honest recommendations that were in my best interest. The situation became even more frustrating when I needed an additional AC/DC converter to support the new panels I purchased from Renu. I reached out to the company approximately one month ago and have yet to receive a response. Multiple follow-up attempts have gone unanswered. The lack of communication and customer support has been unacceptable. When customers invest thousands of dollars in solar equipment, they deserve timely responses and ongoing support. Instead, I have been left with an incomplete solution and no assistance from the company that sold and installed the system. I chose Renu because I expected professionalism and expertise. Unfortunately, my experience has been characterized by unnecessary equipment purchases, long delays, and poor customer service. I hope the company improves its communication and customer support so future customers do not experience the same frustrations.

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!

Awful. Just awful.
If you want salesmen who make promises the company won’t keep, condescending project managers, cost overruns (currently at 33% over original quote, and the project isn't done yet), design errors, and incessant delays (7 months and counting!) then this is the company for you. City inspection was supposed to be today but was canceled, apparently because Renu lost their electrician's license. I can't imagine how *that* happened. Cons: see above. Pros: none. I would not recommend Renu to anyone. Ever. For any reason.

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.

Buyer beware - Contract not Fulfilled
My first year solar production was 57% less than contracted rates. I received 43% of what I paid nearly $40,000 for. I have a contract that states my solar would produce 9602kWh (after change order) for a system that was installed and turned on in October 2024. In July, we knew we were never going to meet that number and something was wrong with the system. We attempted to call several times before I finally emailed multiple leaders at Renu Energy Solutions asking for help on 7/23. What I got was a response from Ariel proving my system was under production and constant disregard of my requests to have someone fix it. We are now 3 months into asking for help and not a single person from Renu has agreed to fix the solar, step foot on my property to look at the solar, or even speak with me on the phone. I believe they have no intent on delivering the production values they quote and use their “we’ll pay your Duke bills” guarantee to profit on over charging for an outcome they don’t intend to deliver on.This was my experience, which may be a one-off or a change in how the company is run. I can’t speak to that, but I can speak to what is currently happening to my household as we speak.

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!

Will not replace the LEMON battery system that they recommended
After 4 months of dutifully coming out to check the batteries (Home 8 ESS by LG), perform multiple fixes and patchwork repairs, the batteries still perform erratically. The fixes either don’t last or don’t work at all. All I get from them and LG is “we don’t see any problems from our remote computer monitoring” They did a great job on the solar panel installation, but the ESS has been a nightmare that has me constantly stressed out. LG took forever to recall and replace a prior model ESS— but only after a bunch of them burned up, so I’m pretty worried they’re going to ignore me over this system too, and Renu backs up whatever LG says. I want Renu to have MY back, and tell LG to send out a new system…. one that works…. SMH Renu: you highly recommended this system, even convinced me to go with it instead of Powerwall— so now back up your words with a Home 8 system that actually works like it should!!!!

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!

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.

I had my system installed in 2018 by Renu. The installation process went smoothly, though I missed out on some of the expected rebate from Duke Energy due to the specific equipment that was selected. My experience of customer service after installation has been extremely poor. I have encountered bounced emails, unreturned voicemails, and a lack of follow-ups. I had an inverter failure under warranty and had to handle the warranty claim myself because I could not get a response from Renu. I have not had system monitoring now for several years because Renu has not updated the monitoring information and I can not restore monitoring myself since Renu is the administrator of my system.
