Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
Solar panels installed on rooftops take advantage of the sun''s energy and convert it into a usable energy source. Solar panels are sometimes called PV (photovoltaic) solar power systems. Home installations of high-quality solar systems can drastically cut or eliminate dependence on the electric company by powering most of your household needs.
5 · He served as the Vice-Chair of the Photovoltaic and Solar Electric Technical Division at the American Solar Energy Society from 2020 to 2021 and currently curates their Solar@Work biweekly newsletter.
Many solar panel systems have two disconnect switches: a DC disconnect (disconnecting the DC current between the solar panels and the inverter) and an AC disconnect (disconnecting your inverter from the grid with grid-tied systems).
