"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."

"Extremely Happy!! I live in Northern CA. I obtained 4 bids from local solar installers and 7 from the EnergySage website. I had done extensive research regarding the ratings for solar panels, inverters, monitoring, etc. SunLux was the first to respond from EnergySage. Their bid was an unbelievably low price for the top of the line Panasonic 320 solar panels, Optimizer inverter and SolarEdge monitoring system. The price was 2/3 ($11K less) than what I had been quoted from 3 of the local companies. When those 3 companies contacted me to see if I wanted to sign a contract with them, they asked why my answer was no. When I told them the price and equipment included, they each said something was wrong and I wasnâ t getting what SunLux quotedâ ¦ it wasnâ t possible. SunLux also beat every other company from the EnergySage website. Because the price was so good, I increased the amount of panels I purchased from 25 to 27. I researched SunLuxâ s reviews and stability and felt comfortable to proceed. They traveled a very long way to install my system; Iâ m the furthest north they have ever been. The crew was great. All were very hard workers and got the job done. I just went online with my energy company towards the end of May 2019. Each of my June and July 2019 energy bills were only $23, which is mostly for the natural gas for the hot water heater. My heating/air is all electric. I am producing more than I using at this time. June and July of 2018 bills were $253 and $435 respectively, including the natural gas. My winter energy bills are very high also. I canâ t wait to see what the net result will be after a year."

"We are so excited that NRG helped us to install Solar Panels on our house in San Francisco! Their entire team was wonderful from their first presentation providing us with all the information to the completion of the installation. Their installation staff was wonderful and completed the project without a hitch. Nicole Greenwood our customer service rep kept us informed of each step along the way and made everything easy. We had gotten estimates from two other companies and are glad we went with NRG. No worries and a wonderful experience. We will recommend NRG without reservation. Thanks to your whole team! Marge B."

"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 average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you’ll need fewer panels if you use below-average amounts of electricity, or more than 22 if you use above-average amounts of electricity. The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment. Since there are so many variables, you should have a professional size your system.

Insurance companies aren’t against solar panels, but they may have concerns about the risks and costs of insuring solar. The type of policy, where you live, and the insurance company itself matter. Extreme weather can damage solar panels, and faulty installation or electrical malfunctions pose a fire risk—this, in turn, can increase insurance company liability and payouts. However, you’re likely to keep coverage as long as you have a pro install the solar system, keep it maintained, can pass a solar panel inspection, and update your homeowners policy to include solar.

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.

While you can minimally overshoot the number of solar panels you need for your home, it's not smart to go too far. Not only is the extra cost unnecessary, but your state may put caps on how much energy your home can produce and send back to the grid. It is always best to work with a solar energy professional to determine the best system size for you.

Solar panels can protect your roof from hail, as they can withstand hail up to 1 inch in diameter that falls up to 50 mph. Your solar panels may experience damage if the hailstones are bigger and travel faster. Your roof can still suffer hail damage, and it’s essential to look for signs and repair issues right away. Roof damage can lead to leaks and water damage inside your home.
