As of 2024, the world record for solar cell efficiency is 47. 6%, set in May 2022 by Fraunhofer ISE, with a III-V four-junction concentrating photovoltaic (CPV) cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the. . Solar panel efficiency is the amount of sunlight (solar irradiance) that falls on the surface of a solar panel and is converted into electricity. Higher efficiency means more power from less space, which is crucial for businesses aiming to maximise energy production on limited roof areas. The difference between an average panel and a highly efficient one can mean fitting a complete solar energy system on a smaller roof—or generating substantially more power from the space you have.
