If you have looked into going solar this year, you have undoubtedly wondered which components will yield the best results. In the solar industry, however, cost isn’t always indicative of quality. Our solar experts looked at a range of criteria and determined the top 5 solar panels in 2021.
We determined the specific solar models you will find below not only get you some of the best power and efficiency ratings, they are the highest rating panels at their price points.
Keep in mind, you may see different pricing for the same system depending on the installer with whom you speak.
Top Solar Panels Evaluation Criteria
How did we determine the top 5 solar panels for 2021?
Above all, the two of the main criteria our experts evaluated were panel power (measured in watts) and efficiency (how well panels convert sunlight to electricity), as they are some of the most common metrics used to compare home solar panel products. While they are not the only means of comparison, they are arguably some of the most important determinants of quality. Metrics like power tolerance and temperature coefficient also play a role in analyzing the potential performance of solar panels.
Ranking 2021’s Top 5 Solar Panels
The following solar panels rated the highest. They have been presented in no particular order other than the top 5. Our solar experts not only provided the list of top panels, but also provided key takeaways and efficiency information that can help you as you explore solar.
