Solar installation companies in the US constantly introduce innovations, helping homeowners and businesses to reduce costs while adopting reliable, renewable power. A typical solar photovoltaic (PV) system consists of panels with photovoltaic cells that convert sunlight into electricity, supporting clean energy production. With the growing demand for solar panel installation in the USA, the industry has witnessed growth over the years.

From residential rooftops to large commercial projects, the top solar installers in the US play a pivotal role in long-term energy security. 

Read on to learn more about the top 10 U.S. solar panel installers turning sunlight into savings and sustainable energy.

Who is a Solar Panel Installer?

A PV installation professional or a solar panel installer assembles, installs, and maintains a wide range of solar photovoltaic systems on roofs and other structures with adherence to site assessment and schematics.

The person should be comfortable working on roofs for extended periods of time and have carpentry, electrical work, and other required skills along with solar installation experience. Most installers have a solar PV certification from the North American Board of Certified Energy Practitioners® (NABCEP®).
