"Joel came out to our home in Grass Valley personally to meet with my husband and I to discuss our solar options. He was patient with our many questions and willing to explain exactly what he had to offer. He realized as we chatted that we could qualify, not only for the normal government rebates, but an extra one due to medical necessity, as we store medications in our refrigerator for our son. We just signed and are excited to work with Joel and his team and our project. It is going to be awesome to save money each year on our power bills!"

"Our phone lines were not working inside of our business. Joe was very helpful and fit me in on a time sensitive issue, he was out the next day! He arrived when he said he would and went the extra mile in making sure we had everything fixed and working that we needed. I would recommend him to anyone needing phone line/jack work. Very friendly and professional."

"His name is Andrew Johnson. He is going to be doing our carport next. He does all of our electrical but he also does incredible solar. It was around $17,000 for the solar. We have a big house. You can't beat his prices. He doesn't have a huge company. His guys are great. He shows up when he says. He does meticulous work. The city's came out and told him right in front us that he did better than perfect. He lives in our neighborhood. He told him to get on Angie's List"

"It went very well. Everyone was very informative. They kept me up to date with the process and whenever I had a question, they were really prompt with their answers whether by email or phone. They were on time when they say they will begin work and the guys that installed my solar panel and inverters were very clean. I mentioned that I'm very worried about leaks because my son is very sensitive to mold and they made sure to seal everything very well n show us the work they've done and ask if we see anything that needs to be addressed. I was very pleased with the whole process. And it was easy, they took care of everything."

Solar Panels questions, answered by experts

No, you cannot turn on a new solar system before inspection. The inspector checks that the system is correctly connected to the grid and that safety components and features are in place. This process prevents problems on the electrical grid and offers protection against fire in your home. 

Your local utility company may also require inspection documentation before you can connect to the grid. An inspection can ensure solar power efficiency and determine how you might increase it.

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.

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.

You can start narrowing your search for a reputable solar company by finding local, regional, and national companies that service your area and maintain positive reviews online. You should also check the Better Business Bureau’s (BBB) website to see if the company has complaints filed against them. Next, contact the remaining candidates and ask about installation timelines, warranty coverage, and financing options. Choose a company that offers a labor warranty that lasts at least 10 years and prioritizes cash purchases and solar loans.

Solar panels should get at least four to six hours of direct sunlight daily. It’s even better if sunlight reaches panels between the peak hours of 10 a.m. and 3 p.m. This is enough to power a home, depending on your solar system’s size and energy needs. Remember that panels will generate some power under cloudy skies or in the shade, and many systems compensate for lower sun exposure by drawing energy from the grid or battery storage.
