Which solar panels are most efficient?
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, Canadian Solar, REC, and Panasonic currently offer the most efficient solar panels on EnergySage.
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?
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.
What is a solar panel efficiency rating?
A solar panel's efficiency measures its ability to convert sunlight into usable electricity. If the sun shines on a solar panel with a 20% efficiency rating, 20% of the sun's energy will convert to solar energy in ideal conditions.
How efficient are large-format solar panels?
For example, LONGi’s Hi-MO X10 commercial-size module reaches up to 24.8% efficiency and 670W output, while several 700W+ utility-scale modules from Trina Solar, Risen, TW Solar, and Huasun now exceed 24.2–24.8% efficiency, highlighting how innovation at the large-format level continues to raise the bar for the entire industry.
How is solar panel efficiency measured?
Solar panel efficiency is measured under standard test conditions (STC) based on a cell temperature of 25 ° C, solar irradiance of 1000W/m2 and Air Mass of 1.5. A solar panel's efficiency (%) is calculated by dividing the module power rating (W), or Pmax, by the total panel area in square meters at an irradiance level of 1000W/m2 (STC).
