The conversion efficiency of a PV cell is the percentage of solar energy shining on a solar panel that is converted into usable electricity. The more efficient a solar panel is, the more energy output it will have per amount of light hitting the cell, which will, in turn, take up less surface area to meet your energy requirements.
The efficiency of photovoltaic solar panels is related to the quality of their photovoltaic (PV) cells. The conversion efficiency of a PV cell is the percentage of solar energy shining on a solar panel that is converted into usable electricity.
Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system.
As explained below, solar panel efficiency is determined by two main factors: the photovoltaic (PV) cell efficiency, based on the solar cell design and silicon type, and the total panel efficiency, based on the cell layout, configuration, and panel size.
Additionally, Progress in Photovoltaics publishes listings of the latest PV cell technologies twice a year - Version 64 of the efficiency tables was released in July 2024 and is free to read. The latest version 65 of Solar cell efficiency tables, released in November 2024, is now available but requires a login or payment.
Solar panel conversion efficiency, typically in the 20% range, is reduced by the accumulation of dust, grime, pollen, and other particulates on the solar panels, collectively referred to as soiling.
