Best Solar Panels for Your Home in 2025:
Our reviewers have spent hours reading solar panel spec sheets and devising a scoring methodology that measures what matters most to solar
Of all of the companies that we researched, the average efficiency rating for solar panels was 21.33%. Efficiency ratings ranged from 17.45% to 26.6%, so check the specs on any panels you're considering to make sure your panels perform to the best of their ability. How long do solar panels last?
For example, say Panel A has an efficiency rating of 15% and Panel B has an efficiency rating of 20%. If both get exactly the same amount of sunlight in one day, Panel B will make more electricity because it converts more of that sunlight into power. Do shade and temperature affect solar panel efficiency?
As highlighted in our guide to choosing a quality and efficient solar panel, when selecting panels, higher-cost panels from the leading manufacturers generally offer better quality, higher efficiency and increased reliability. Solar panels from the manufacturers listed below have proven to outperform and outlast most cheaper panels.
