Efficiency is measured fairly simply. If a solar panel has 20 percent efficiency, that means it’s capable of converting 20 percent of the sunshine hitting it into electricity. The highest efficiency of solar panels can reach almost 23 percent, which is impressive considering the first solar modules were only 6% efficient.
What does ‘solar panel efficiency’ mean? ''Solar panel efficiency'' refers to the amount of naturally occurring light a solar panel can convert into electricity in standard test conditions, which is a set of environmental factors used across the industry to measure efficiency.
The difference between an average panel and a highly efficient one can mean fitting a complete solar energy system on a smaller roof—or generating substantially more power from the space you have. Today, most panels are at least 20% efficient, but the best ones convert over 22% of the sun''s energy into electricity.
The most efficient solar panel available for homes today is Maxeon’s 440-watt panel at 22.8% efficiency. Solar panel efficiency is the percentage of incoming sunlight that a single solar panel can convert into electricity. Maxeon, Qcells, Solarever USA, Canadian Solar, and REC currently offer the most efficient solar panels on EnergySage.
