"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

Installing solar panels involves drilling small holes in your roof to secure the solar panel mounting brackets. These brackets hold the solar panels in place and must withstand strong weather conditions so they’re secured into your roof. However, holes and screws are sealed to prevent leaking and further damage.

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.

Solar shingles and solar panels are not the same. While solar shingles use the same technology as traditional solar panels, they integrate with your existing roof. That means they are used to build your roof instead of simply resting on top of it. When comparing solar shingles and solar panels, it's helpful to know that solar shingles are more aesthetically pleasing than solar roof panels. They also do better in harsh weather due to limited uplift from strong winds.

Yes, it is possible to install solar panels on a tar and gravel roof, but it is not the ideal roofing material for a solar installation. The process requires roof penetrations to install the solar racking system. While installers will seal these penetrations, they still increase the risk of leaks. This risk is higher on tar and gravel roofs, which are often flat. Flat roofs are more prone to leaks than sloped roofs because they can pool water during heavy rain and hold snow for longer periods, exposing the roof to more moisture.

Ideally, you want to place them facing true south. This is different from what a compass shows, which is called the magnetic south. You can find true south by using an online calculator as long as you know the longitude and latitude of your property. Solar panel placement is key to maximizing the energy you generate, so this is an important step.
