What is solar panel efficiency?

'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.

Why does solar panel efficiency matter in the UK?

If a panel is 20% efficient, it means 20% of the energy in the sunlight reaching that solar panel is turned into usable electricity. The more efficient your solar panels, the less reliant you’ll be on perfect conditions to generate electricity, and the fewer panels you might need. This is the reason solar panel efficiency matters in the UK.

Do solar panels generate more electricity?

As a measure of how well solar panels can convert sunlight into usable electricity, a more efficient solar panel will generate more electricity than a less efficient unit when exposed to the same amount of sunlight.

How efficient are solar panels in 2024?

In 2024, the average efficiency is about 21.4%, which translates to 10% more electricity produced per panel. Within those averages, you'll find solar panels with a range of efficiency ratings. It might not surprise you that you'll usually pay more for solar panels with greater efficiency.
