Solar Panels questions, answered by experts

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 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.

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.

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.

The cost to install solar panels is around $27,000 on average, but you could pay between $4,500 and $54,000 or more, depending on a few factors. Some of the most influential cost factors for installing solar panels include the following:

  • Size of the system you need to offset your energy consumption

  • Amount of sunlight 

  • Brand of solar panels 

  • Add-on products, like solar batteries or electric vehicle (EV) chargers

  • Labor costs of the company 

  • Home’s geographical location
