Currently mass-produced solar panels have a power generation efficiency

Do solar panels produce more power?

Given the same amount of sunlight shining simultaneously on two equal-sized solar panels with different efficiency ratings, the more efficient panel will produce more power than the less efficient panel. Solar panels comprise multiple silicon solar cells, which determine their overall efficiency rating.

How efficient are solar panels?

For example, if a panel has 20% efficiency, it turns 20% of the sunlight it receives into usable energy. While that may sound modest, it’s a huge achievement given the complexity of the conversion process—and it’s steadily improving. Most residential and commercial solar panels available in 2025 achieve efficiencies between 18% and 23%.

What is the most efficient solar panel?

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.

What's the difference between an average and a highly efficient solar panel?

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.
