A clear explanation of how solar photovoltaic systems convert sunlight into electricity — covering the photovoltaic effect, cell types, modules, string inverters vs. microinverters, and system efficiency factors.
Solar panels generate electricity through the photovoltaic (PV) effect, discovered by Alexandre-Edmond Becquerel in 1839. When photons (light particles) from the sun strike a semiconductor material, they can knock electrons loose, creating a flow of electric charge. Silicon — the same element used in computer chips — is the dominant semiconductor material in solar cells.
