Choosing between becoming a solar installer or a lineworker means choosing between two different paths within the growing energy industry. Although both careers involve electricity and renewable energy, their daily responsibilities, work environments, technical skills, and career progression are very different.
Solar installers, also called solar photovoltaic (PV) installers, design, assemble, install, and maintain solar energy systems on residential, commercial, and utility-scale properties. Their work focuses on converting sunlight into usable electricity through solar panels, inverters, batteries, and related electrical components.
Lineworkers, officially classified by the U.S. Bureau of Labor Statistics as electrical power-line installers and repairers, build, maintain, and repair the electrical infrastructure that delivers electricity from power plants and substations to homes, businesses, and communities.
The difference between these careers is the difference between installing distributed energy systems and maintaining the electric grid infrastructure.
Solar installers help expand renewable energy generation.
Lineworkers keep the power network operating safely and reliably.
