Very happy with the install

Renu team did a great job from the sales to install. I had engaged with them almost a year prior to the house construction completed. Renu involved in the solar panels and battery planning from the beginning working with the builder and included necessary steps as part of the construction. In the end everything was very smooth, wires hidden in the walls (no outside runs).. I am very happy with everything.

Deceptive sales- disappointing experience

They quoted incentives that didn’t exist (not expired, they just didn’t apply to the system they quoted me), so it felt very deceptive or extremely poor quality control. They also had to issue a change order to switch inverters which negatively impacted the expected production of the system. Overall really disappointing experience that I hope others don’t have to go through. I’d recommend selecting another vendor.

Happy Campers!

We are so happy with our solar project. Renu gave us a very competitive price. The coordination and communication was fantastic. They held our hand during planning, permitting, and construction. Every member of the team was professional, personable, and a delight to work with. I can’t recommend them highly enough.

Renu Energy 12KW Solar and FranklinWH Install

I worked with Renu Energy Solutions to install a 12kW solar system and two Franklin aPower2s. From initial sales to job completion, Renu was easy to work with and responsive to my questions and needs. The installation was finished early July 2025, and PTO was granted a few weeks later. I've been running the system without any issues since. While the up front cost might seem high to some, Renu provided the best price for the system I wanted after researching several quotes, and I appreciated that everything was managed in-house, eliminating concerns about dealing with difficult contractors.

Quality Organization

Daniel in sales, Megan the project management, and Anna with marketing team were great to communicate with prior to the install. Additionally, the installation technicians mostly from Columbia, SC and a couple others from the Charlotte office completed everything by midafternoon while the electricians had to work around some additional contractors inside the house. We’re optimistic that the system will perform as designed and deliver the long-term benefits we’ve planned for.

Stop door knocking

NO SOLICITING MEANS NO SOLICITING! stop knocking on our doors. I already have solar panels so I'm not sure why your dumb salesmen thought I would want more! Learn to read signs printed bold in plain english. NO SOLICITING
