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 average efficiency of solar panels in terms of real-world performance may be lower than under laboratory conditions due to various factors such as partial shading, dust, and bird droppings, which can obstruct sunlight. Weather conditions like cloud cover, humidity, and high temperatures can also affect efficiency.
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. Today, most panels are at least 20% efficient, but the best ones convert over 22% of the sun''s energy into electricity.
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.
