"Awesome company, not only did i get the best financing, because i shopped all their competitors, but on top of going GREEN and reducing my SRP Bill, they also financed my new flooring and pool upgrade at the same rate. Saved me thousands in payments versus a traditional HELOC!!!"

Solar Panels FAQs, answered by experts

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

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. 

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.

In most cases, installing solar panels will not void your roof warranty. To keep roof warranties intact, check your written warranty or call the manufacturer to ask about clauses regarding roof penetrations. You can also protect yourself by getting written approval or a modified warranty that specifically allows the solar installation type you’re planning. Then, hire a professional solar installer that follows roofing manufacturer instructions and protects the roof during installation.

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.
