Over the last decade, there has been a significant increase in the number of homeowners installing solar panels on their homes. An analysis by Vote Solar reveals that more than 2.5 million American homes had solar panels installed as of 2019 - up from just 1.2 million homes as of 2018. This level of growth is largely due to recent legislation by state governments to require utilities to source their electricity from renewable sources like solar, wind, and geothermal power.
Solar energy is a sustainable, renewable power supply that produces no toxic byproducts, and requires little maintenance. However, the upfront costs of installation can be quite high. In addition to installing solar panels on roofs of buildings, many people are opting for solar panel installations on their siding for a more cost-effective option. The solar panels can be made from a variety of materials including metal and plastic to match the color of a home.
