Power (measured in watts) and efficiency (how well panels convert sunlight to electricity) are some of the most common metrics used to compare solar panel products. While they are not the only means of comparison, they are important determinants in how much electricity you can produce with a solar panel system. Metrics like power tolerance and temperature coefficient are also important ways to analyze the potential performance of solar panels under the different conditions they will experience over their lifetime. Learn how panels from different manufacturers stack up against one another in our updated article about the best solar panels on the market.
