Homeowners do save money and help the environment when they use the sun's energy to power their homes. These aren't the only benefits of solar, though. Below is an in-depth look at the advantages of installing solar panels.

What are the benefits of rooftop solar panels?

Typically roofs are exposed to the elements day in and day out, be it harsh sunlight or heavy rains, or snow. As rooftop solar panels take on the brunt of the weather conditions and won't allow them to reach the rooftops, the roofs stay protected. Moreover, the gap between the roof and the solar panels prevents the roofs from getting too hot.

Do solar panels need a slanted roof?

You have to position solar panels properly to achieve the highest energy production. The optimal orientation and angle usually require a slanted roof that faces the sun. Some roofs have a unique shape that might not accommodate rigid, flat panels. For those homes, flexible solar panels can be a good workaround.
