Solar Panel Efficiency explained. 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 23%.
Maxeon, formerly SunPower, remains the leader in residential solar panel efficiency, holding the top spot with its limited production 7 Series panels. However, Aiko Solar has taken the spotlight with its larger commercial-sized panels, achieving an impressive efficiency of 24.2%.
Solar panel efficiency tends to range between 13% to 25% but can be as high as 40% or 50% for some high-end and experimental systems. This guide explains what solar panels and cells are, what makes them more or less efficient, and some of the different types of solar panels on the market. What Are Solar Panels and Solar Cells?
The efficiency of a solar panel is affected by numerous factors. Some solar cell types are inherently more efficient than others. Construction techniques and the materials used also have an impact on the efficiency of a solar panel. The location and orientation of solar panels affects their efficiency.
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.
The location and orientation of solar panels affects their efficiency. For example, south-facing panels (in the northern hemisphere) will capture more sunlight and therefore be more efficient. The best solar panels are tilted. This makes them perpendicular to the sun’s rays, which also makes them more efficient.
