Most home solar panels are between 21% and 22% efficient, but many manufacturers are achieving efficiencies of 23% and higher. The most efficient residential solar panels come from Maxeon, with a 24% efficiency rating. Other high-efficiency solar panels on the market come from JA Solar, REC Group, VSUN, and Canadian Solar.
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.
In June 2024, researchers at Chinese solar company LONGi created a perovskite-silicon cell with a record-breaking 34.6% efficiency. In June 2025, China's GCL broke the record for a whole panel, achieving a 29.51% efficiency rating – and just a few days later, rival firm Trina Solar went one better with a panel that's 30.6% efficient.
Let's explore the key advantages of using high-efficiency solar panels. Efficient solar panels convert more sunlight into usable electricity which results in higher energy output. This means you get more power from the same amount of sunlight compared to less efficient types.
Other high-efficiency solar panels on the market come from JA Solar, REC Group, VSUN, and Canadian Solar. The efficiency of solar panels is impacted by the type of solar cells used, the direction and
