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%. Guidelines for inclusion reviewed. An appendix describing temporary electrical contacting of large-area solar cells approaches and terminology is also included.
