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. 1%, set in 2019 by multi-junction concentrator solar cells developed at. . For example, a solar panel with 20% efficiency and an area of 1 m 2 produces 200 kWh/yr at Standard Test Conditions if exposed to the Standard Test Condition solar irradiance value of 1000 W/m 2 for 2. Usually solar panels are exposed to sunlight for longer than this in a given day. . Solar panel efficiency is a measurement of how much of the sun's energy a certain panel can convert into usable electricity. . Progress has slowed in recent times, but having reached a top efficiency rating of 25%, domestic panels are effective enough to make the most of any space you have on your roof.
