Technical FAQs 4

Are solar panels more efficient?

Highly efficient solar panels tend to cost more than their less efficient counterparts. But, the higher your panel's efficiency, the more electricity you'll produce, and the more you'll save on your electric bills.

What's the difference between an average and a highly efficient solar panel?

The difference between an average panel and a highly efficient one can mean fitting a complete solar energy system on a smaller roof—or generating substantially more power from the space you have. Today, most panels are at least 20% efficient, but the best ones convert over 22% of the sun's energy into electricity.

Are solar panels cost-effective?

To understand the cost-effectiveness of each panel option, calculate whether the increased savings you achieve by generating more electricity over the lifespan of your solar energy system with high-efficiency panels justifies the higher upfront cost. Let's consider two solar panel systems located in Massachusetts.

What are the best solar panels?

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: Maxeon, Qcells, Solarever USA, Canadian Solar, and REC. The catch? Higher efficiency usually comes with a higher price tag.
