Solar Panel Efficiency explained. 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%.
The most efficient solar panel available for homes today is Maxeon’s 440-watt panel at 22.8% efficiency. Solar panel efficiency is the percentage of incoming sunlight that a single solar panel can convert into electricity. Maxeon, Qcells, Solarever USA, Canadian Solar, and REC currently offer the most efficient solar panels on EnergySage.
Given the same amount of sunlight shining simultaneously on two equal-sized solar panels with different efficiency ratings, the more efficient panel will produce more power than the less efficient panel. Solar panels comprise multiple silicon solar cells, which determine their overall efficiency rating.
Solar panel efficiency is measured under standard test conditions (STC) based on a cell temperature of 25 ° C, solar irradiance of 1000W/m2 and Air Mass of 1.5. A solar panel''s efficiency (%) is calculated by dividing the module power rating (W), or Pmax, by the total panel area in square meters at an irradiance level of 1000W/m2 (STC).
