Get matched with top solar panel pros in Warren, RI

You can install solar panels on a flat or pitched roof, but keep in mind that they will need to rest at a 30- to 50-degree tilt for optimal sun absorption. It costs more to install solar panels on a flat roof because you will need to install a framing system and likely hire a structural engineer. If your roof has a pitch of more than 40 degrees, it may not be a good candidate for solar panels.

No, you cannot turn on a new solar system before inspection. The inspector checks that the system is correctly connected to the grid and that safety components and features are in place. This process prevents problems on the electrical grid and offers protection against fire in your home. 

Your local utility company may also require inspection documentation before you can connect to the grid. An inspection can ensure solar power efficiency and determine how you might increase it.

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. 

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.
