- The efficiency of solar panels is influenced by factors such as the type of solar cells, installation methods, and local climate and weather conditions.
What does solar panel efficiency mean?
Solar panel efficiency refers to how effectively solar panels convert sunlight into usable electricity. The higher the efficiency rating, the more electricity the panel can generate from the same amount of sunlight.
Most residential solar panels have efficiency ratings between 19% and 21%. However, with advances in solar technology, more manufacturers are reaching efficiency levels of 22% or higher. For comparison, data from the National Renewable Energy Laboratory shows that the average solar panel efficiency was only 14.1% in 2010. Solar panel efficiency has significantly improved over time.
While a 22% efficiency may not seem impressive, it’s important to remember that most systems don’t operate anywhere near 100%. For example, according to Penn State University, gasoline car engines are about 25% efficient, and power plants operate at around 36% efficiency.
