Solar panel efficiency determines how much electricity a solar panel installation will produce. Energy efficiency of solar cells and panels refers to how much of the sunlight that hits the surface of the panel is converted into usable electricity.
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 best solar panel on the market at the moment in terms of efficiency is the Maxeon 7, which is 24.1% efficient. The chart below is based on a report from the US government-funded National Renewable Energy Laboratory, who have recorded all major breakthroughs in solar cell efficiency since the mid-1970s.
Different solar panel technologies perform differently in low-light conditions: High efficiency, better performance in low light. Moderate efficiency, decent performance in low light. Best in low-light environments, less affected by shading. Location and climate play a critical role in determining the effectiveness of a solar panel installation.
For example, if a solar panel has an efficiency of 20%, it means that if 100 units of solar energy are incident on the solar panel, 20 units of solar energy are converted into solar electricity. A higher solar efficiency offers several advantages such as it can generate more energy.
Solar panels have rapidly increased in efficiency over the past few decades. Progress has slowed in recent times, but having reached a top efficiency rating of 24%, domestic panels are effective enough to make the most of any space you have on your roof.
