How efficient is a solar panel?
You’ll see this ability shown as a percentage – so if a solar panel is 22% efficient, that means it can turn 22% of the natural light that hits it into electricity for your home. To measure solar panel efficiency, manufacturers use standard test conditions (STC), a universally accepted controlled environment used by companies all over the world.
How efficient are solar panels in 2025?
Basically, the more efficient solar panels are, the more power they can generate. In 2025, its standard for residential solar panels to be between 21% and 22% efficient – but many brands are reaching ratings in the 23% range. Here are the most efficient solar panels that are currently available in 2025: Is solar panel efficiency important?
What is the maximum solar panel efficiency?
In the residential market, the most efficient solar panels come from Maxeon and are 24.1% efficient. Larger, utility-scale solar panels can be more efficient than residential panels and technology still in research phases has almost doubled that efficiency.
Which residential solar panels have the highest efficiency ratings?
Our CNET experts have found the market's top performers with the highest efficiency ratings. The most efficient residential solar panel right now is the Maxeon 7, which dethroned the older Maxeon and Canadian Solar panels when it launched in February 2024.
Which solar panels are most efficient?
Material: The most efficient solar panels use monocrystalline silicon, which is more efficient than polycrystalline or thin-film options. Temperature coefficient: Solar panels perform best in cooler conditions. The temperature coefficient tells you how well a panel maintains its efficiency as the temperature rises.
How efficient are Maxeon solar panels?
If you’re aiming for top-notch solar efficiency, Maxeon solar panels lead the way, boasting an impressive panel efficiency of up to 24.1% in real-world conditions. Why does that matter? Higher efficiency means better sunlight-to-energy conversion, which means more electricity production and bigger savings on your power bill.
