"Having Sunpower install our Solar panels has been a great experience. Arvin helped explain the system, process the paperwork, and made sure the installation and inspections were all done on time. Sunpower system has saved us alot in electrical costs. We are so happy with how this has turned out. Our system is actually performing 25% more efficiently than expected!! A big thanks to Arvin for all his help throughout this process."

"Initially, I questioned the utility of solar panels: how much they reduce the cost of electricity, how quick & easy the installation goes, etc. So for years, I passed up every opportunity that arose to get solar panels done. Eventually solar panel systems began popping up everywhere and I knew the benefits were no longer a fantasy. I called a few places and ended up with SunLux who offered the most competitive prices. My sales representative Trang Phung explained a structure that was easy to understand and made me so much more comfortable with the process. Installation was brief and my energy bill has been drastically reduced! If you're on the fence about solar panels - don't be. SunLux will take care of you! -Kim Nguyen"

"" Reyes Leyba Review from San Ysidro, CA " I went with solar because I wanted to save money on electricity and also raise up the house value. Reece came over to my house and explained the benefits of going solar. He looked at my bill and went over everything I needed to get the project started. Installers were 10 out of 10. They were really nice guys and did a really nice clean install. My black on black solar panels look wonderful on my roof. Tiffany was a great coordinator and always kept my informed on what to do. Took care of the project and made sure I was satisfied. Also great job for Robert who helped look over the solar with me. Great help from him and everybody else because it is my first time getting solar, and now I feel more comfortable using my system."

"I brought to the attention the 1 panel that had a sagging corner, my comment was ignored. Just this month I received an e-mail asking if I could use any additional services to me, in response I asked about the sagging corner and an unrelated technical question. They addressed my question but not my sagging corner. This is the reason I did not give them all 5 stars."

Solar Panels questions, answered by experts

The best way to save money on solar panels is to take advantage of federal and state solar incentives. For example, the solar investment tax credit (ITC) offered by the federal government can save 30% of your total—if you can take the entire credit, which is based on income taxes owed—or an average of around $9,000. You can check the Database of State Incentives for Renewables and Efficiency (DSIRE) for state and local incentives that could save you even more.

Yes, solar panel installation will require permits. The required permits will depend on where you live, as some states and cities have solar-specific permits, while others only require electrical permits to connect to the grid. In either case, it’s best to hire a reputable solar installer in your area, as a representative should handle all of the necessary permitting for you and will include the cost of the permits in your initial solar estimate.

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.

Although solar panels harness the sun's power, they come at an environmental cost. The manufacturing process requires large amounts of water and involves hazardous materials like cadmium, silicon, and gallium arsenide. These materials don’t pose safety hazards while the panels are in use but can pose a problem when left in landfills. Over time, hazardous materials can leach into the environment. This is why recycling solar panels whenever possible is better than taking them to landfills.

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.
