Not all solar panels produce the same amount of electricity from sunlight. 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.
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.
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.
From the materials used to the design and technology, a solar panel's efficiency depends on several factors. Some panels can squeeze more energy out of the same amount of sunlight, saving money and space in the long run. Let's dive into what sets the high performers apart and why it matters for anyone considering solar power.
