"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."

"Target Electric Enterprises Inc replaced and upgraded my 50 year old main electric panel and I’m so glad I selected them for the job! Sean was responsive from day 1 and kept me fully informed throughout the process. My job required installing a new underground cable also, which involved several interactions with SDGE and City of San Diego, and Sean and Steve very capably handled every step with skill and efficiency. In the field, Steve has extensive expertise and obviously takes great pride in getting the job done right. Their pricing was also very reasonable, and I totally recommend them for any electric job, small or large!"

"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!"

"We decided to upgrade to solar/battery. After extensive research we selected McKay (now Nuonenergy) for both re-roofing and solar/battery install. Reason for choosing them was due to competitive price, single source for both re-roofing and solar/battery install as well as a very helpful and friendly sales team. The install went smoothly. Explained workflow in advance the completed work in a timely fashion. Work was completed by different teams all of whom were professional and friendly. They left worksite clean and communicated next steps in advance so we could plan our day. System install now completed, including all inspections by city and electrical provider. Very satisfied with the service we received from McKay/Nuonenergy."

"i could not be happier with OC Solar, they deserve all of the hype! i have worked with Vinnie and the oc solar team for over 5 years and done many projects with their team. they are always on time, priced well, easy to work with, and the communication is excellent. itâ s hard to find good contractors, so when you find one, you have to tell people, and OC Solar is worth putting my name on the line for. we have had them install Tesla power walls for us, specifically the tesla power wall 3. they have installed Panasonic and q cell panels for us and the installation quality is top of the line. highly recommend, 10/10. choose ur installer wisely, los Angeles is not easy to work with, so i recommend a proven company like OC Solar"

"They scheduled appointment thru phone and text and even. Once they arrived they repaired what was needed, let me borrow a hose to top off my pool, and even gave me an education on how the pool equipment operated. Even then they came in under what they orginally estimated. Would suggest to anyone who need solar panel repairs."

Solar Panels FAQs, answered by experts

Professionals use the same methods to install solar shingles that they do for asphalt shingles, so you’ll often see a similar installation timeline of one to two days. The amount of time required will depend on the size and slope of your roof and the number of shingles installed. Weather conditions can delay installation, as working on a roof is unsafe during high winds or heavy rain.

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.

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.

DIY solar panel installations are hard to manage by yourself. You’ll likely need some help or prior experience to make the project worth the effort.

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.
