"I initially had reservations about the concept of installing solar panels, but I was keen on getting an estimate and seeking professional advice. That's when I met Arvin. He provided me with a comprehensive walkthrough, clearly outlining the advantages of having solar panels. The entire process was straightforward, with each step being well-explained, leaving no room for surprises or unexpected outcomes. Now, a little over 5 months since the installation, I'm enjoying the benefits just as he promised. I want to extend my gratitude to Arvin for his professionalism and responsiveness. He was always there to address any questions I had, both during and after the installation process. Thank you, Arvin!"

"They did excellent job and were professional from beginning to end! I had another solar panel company come before SunPro. They told me I was not allowed to get solar panels because my bill did not reach a certain amount. Which Sunpro did not tell me. They put the panels were I wanted them to go, and were extremely professional. I have the service representative, Cara, in my phone and any time that I need something or have a question she is there. Very knowledgeable and they answer at all hours."

"Roberto Sanchez Solar System, I interviewed 4 solar panel companies and I chose NRG because Will was able to explain everything well. He answered all my questions to my complete satisfaction. Friendly and honest, Will made the sales process very smooth and personable. Tiffany helped and coordinated the project to make sure everything goes well. She always got back to my emails and phone calls promptly. Installers completed the solar panels when I was at work. Came home and he solar panels were on the roof. Definitely a nice install and quality work was delivered. Lisa helped out with the financing on the HVAC. She was patient and I believe got me a lower amount that before. Solar edge app is great to use and straight forward. Highly recommended company thanks NRG. I am excited to use my new solar system!"

"Jovan is arguably one of the best salesman that has ever came to my doorstep. My fiancé & I were first skeptical about getting solar panels but he was very informative about the benefits solar panels have for homes now a days. He was respectful when it came to making my decision but also very attentive and checking up on me throughout the process of getting an installation date for my home. He was very responsive when it came to any questions I had about the installation, he also came to my house the day before and day off to make sure everything would run smooth, he gave me a call after the installation was complete as well. I would recommend Jovan to any of my neighbors who have not gone Solar yet. If you need solar, Jovan is your guy. By far any means necessary get with Jovan to get your solar needs taken care of."

"Exceptional customer service. Superb quality of systems available and very esthetically pleasing. They were quiet and very clean being respectful of my home, property and neighbors. Bobby took the time to educate me on the system and followed up to ensure I understood everything I needed to know. Sales people to the technician were extraordinary. Pro Solar really cares about their customers. I absolutely recommend this company without hesitation."

"It turned out good. It took them a long time to get the gift card to me but other than that everything went fine. Every time I talked to somebody I would tell them it's an Angie's List Big Deal and I think that some place along the line somebody didn't  pay attention to that. I don't know if there's a commission involved on the other end or something, so I had to call back two or three times to get it all finished up and get the gift card and I think they even had to have a refund. It was a little bit of a hustle. It took a lot of time for the right person to get what I needed."

Solar Panels questions, answered by experts

Learn about common solar blockers in your area to determine how often you should wash solar panels and the best cleaning method:

  • Soot: If you have a fireplace, soot can disperse and accumulate on the solar panels.

  • Debris, dirt, and leaves: These natural elements require light cleaning. Being close to trees or living in a desert area can cause more of these to accumulate.

  • Pollen: Areas with a high pollen count require more frequent solar panel cleaning, and sticky plant material requires a deeper cleaning.

  • Bird droppings: Bird droppings are binding and more difficult to remove. Keep this in mind if you live near a lot of surrounding trees. 

Rooftop solar panels supply energy to a single household, where a solar farm can power multiple homes at once with clean energy. Residential rooftop solar panels cost more per watt with a lower project total, and those panels only service the residence they are installed on (in most circumstances). With a solar farm, multiple households can buy into the project and share the overall cost.

Yes, a solar panel can power a TV without a battery, but only if the sun is shining and the panel is generating enough energy. Your solar panel and TV must have the same voltage, and you should install a charge controller and inverter between them so power surges don’t destroy your TV. To watch TV at night, in the early morning and late afternoon, and on cloudy days, your home must be tied to the power grid.

The best way to know if your roof can support solar panels is to hire a structural engineer. They’ll look at your roof and approve the design of your solar panel system or suggest changes. The best roofing for solar panels is made from strong materials like asphalt shingles and metal, but tile and gravel will work. Softer materials like thatch or temporary structures are not a good fit.

It’s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation—such as roof leaks and mounts that aren’t sealed properly—can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.
