Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via into electricity by the. The efficiency of the solar cells used in a, in combination with latitude and climate, determines the annual energy output of the system. For example, a solar panel with 20% efficiency and an area of 1 m produces 200 kWh/yr at Standa.
