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.

The physical characteristics of a solar panel have an impact on the product’s performance. For example, metrics like efficiency and wattage are based on the type, size, and number of solar cells used in a panel.
Solar panels are made all around the world. While the bulk of solar panel manufacturers are based in Asia, companies in the United States, Canada, and other countries also produce high-quality photovoltaics.
