The efficiency of solar panels has improved dramatically in recent years, from around 15% conversion of sunlight to usable energy, to around 20%. In fact, the current industry-average efficiency for a single residential solar PV panel is about 21%, with the top-performing units able to achieve up to 23%.
Solar panel efficiency ratings represent how effective a solar panel is at converting sunlight into electricity. The percentage indicates the efficiency level, with most residential solar panels ranging between 15-20%.
The best solar panel on the market at the moment in terms of efficiency is the Maxeon 7, which is 24.1% efficient. The chart below is based on a report from the US government-funded National Renewable Energy Laboratory, who have recorded all major breakthroughs in solar cell efficiency since the mid-1970s.
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.
Solar panels have rapidly increased in efficiency over the past few decades. Progress has slowed in recent times, but having reached a top efficiency rating of 24%, domestic panels are effective enough to make the most of any space you have on your roof.
Solar panel efficiency is determined by scientists in controlled laboratory conditions under the Standard Test Conditions (STC) of a sunny day with a temperature of 25°C and irradiance of 1000 W/m2. This measures how much solar energy the cells can convert to electricity.
