4 FAQs about Solar panels generate electricity with high efficiency

How does solar panel efficiency work?

The more efficient your panels, the more power you can generate from every square metre of roof space. In this guide, we explain how solar panel efficiency works, how it's measured, and how much energy you can expect from today's systems. Use our comparison tool to get a range of quotes from leading solar panel installers across the UK.

What does'solar panel efficiency' mean?

What does 'solar panel efficiency' mean? 'Solar panel efficiency' refers to the amount of naturally occurring light a solar panel can convert into electricity in standard test conditions, which is a set of environmental factors used across the industry to measure efficiency.

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.
