Find prices for solar panels and compare technical specifications of various brands and models of modules in our regularly updated solar panel comparison table. . Solar panel efficiency is the amount of sunlight (solar irradiance) that falls on the surface of a solar panel and is converted into electricity. Due to the many advances in photovoltaic technology over the last decade, the average panel conversion efficiency has increased from 15% to over 24%. I have to note however that the data listed in the specification sheets are normally measured at an optimum load of the module under some ideal conditions called Standard Test Conditions (STC). Access our research-cell efficiency data. Compare panels to see which may be best suited to your home. . How many high-efficiency solar panels do you need? Most home solar panels are between 21% and 22% efficient, but many manufacturers are achieving efficiencies of 23% and higher.
