Today, most panels are at least 20% efficient, but the best ones convert over 22% of the sun's energy into electricity. After reviewing hundreds of solar panel models, we found five brands that lead the pack: CW Energy, Maxeon, Qcells, SEG Solar, Silfab, and CertainTeed. Due to the many advances in photovoltaic technology over the last decade, the average panel conversion efficiency has increased from 15% to over 24%. High-efficiency panels tend to generate more power, making them more likely to maximize your energy savings over. . The company weighted its rankings based on performance, including panel efficiency, output per square foot and temperature coefficient. It also assessed product warranty, including power and product warranty lengths and additional criteria related to labor, shipping, and more.
