What is the average efficiency of photovoltaic panels

Solar Panel Efficiency (2026) | ConsumerAffairs®

A good residential solar panel today typically has an efficiency rating between 20% and 22%, meaning it converts about one-fifth of the sunlight it receives into electricity.

Solar Performance and Efficiency

Factors Affecting Conversion EfficiencyDetermining Conversion EfficiencyAdditional InformationResearchers measure the performance of a PV device to predict the power the cell will produce. Electrical power is the product of current and voltage. Current-voltage relationships measure the electrical characteristics of PV devices. If a certain "load" resistance is connected to the two terminals of a cell or module, the current and voltage being...See more on energy.govnrel.gov[PDF]
