"Smart Wave Solar did a superb job of every thing from start to finish with installing my solar panels. After comparing them to many other companies they were by far the least expensive for top quality panels. Even with Covid stuff going on that caused some pinch points they manged to get things done in a reasonable time frame. I am happy so far with my purchase, the service and the over all results of their work. Would highly recommend them to anyone looking to get into solar."

"The tech showed up a little early which I appreciated; nothing worse than being late for an appointment. He quickly diagnosed the issue with our solar system and is working to get a new inverter under warranty from the manufacturer. He also installed a critter guard to keep the birds from nesting under our panels."

"The solar electric system is now installed and functional 5.5 KW Grid tie system. Standard Relewable sub-contracted much of the work, and I had to deal with several Standard Renewable people over the course of the project. I paid in two payments by credit card. They were very slow to make arrengements to take the second payment. There were several times when it was difficult to get response by email. I emailed several times to make the final payment, and could not get them to do so. The conduit in the Attic is run so that it crosses open space at head knocking height. Over all the system is installed and working, but lacks fine touches"

Solar Panels FAQs, answered by experts

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.

Learn about common solar blockers in your area to determine how often you should wash solar panels and the best cleaning method:

  • Soot: If you have a fireplace, soot can disperse and accumulate on the solar panels.

  • Debris, dirt, and leaves: These natural elements require light cleaning. Being close to trees or living in a desert area can cause more of these to accumulate.

  • Pollen: Areas with a high pollen count require more frequent solar panel cleaning, and sticky plant material requires a deeper cleaning.

  • Bird droppings: Bird droppings are binding and more difficult to remove. Keep this in mind if you live near a lot of surrounding trees. 

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.

While solar panels can be a great investment, they aren’t ideal for every roof. For example, some roofs, especially older or structurally weak ones, may struggle to support the added weight, leading to potential damage. Roofs with complex designs, obstructions, or limited sunlight exposure might not provide optimal conditions for solar energy production. Consider these downsides when determining if solar panel installation costs are worth it.

In most states, solar installers need to be licensed and insured as solar professionals, although some states don’t have specific requirements for installers. You can use our state licensing tool to check if an installer you’re considering hiring holds the proper licensing. No matter where you live, a member of your solar panel installation company must be a certified electrician to connect your panels to your home and the electric grid.
