The most efficient solar panel 2018.

What is solar panel efficiency. When it hit the market in 2017 sunpower s x 22 series solar panel dethroned all competitors in the residential market for the title of the most efficient solar panel. On average a solar cell will convert about 15 percent of the sunlight that hits it into usable electricity. Right now sunpower manufactures the most efficient panels on the market the series x which boast a whopping 22 8 efficiency rating.

A 5 kilowatt solar rooftop system using sunpower s most efficient panels would need 15 of sunpower s 41 inch by 61 inch panels. Though they will come with a higher price tag sunpower will often be the consumer. By that metric the lg panel could produce the most power per panel. What are the most efficient solar panels in 2020.

The price premium for solar panel efficiency sunpower panasonic and lg currently manufacture the most energy efficient solar panels available on the market with an average efficiency rating of 22 2. Two of its monocrystalline x series panels rank as both the most efficient solar panels on the market with a peak efficiency of 22 1 and 21 5 respectively and were also the most installed residential solar panels in america in 2018. Sunpower offer the longest product warranty of 25 years to go with their 25 year power output warranty. Kyocera spec sheets do not have efficiency numbers but they claim cell efficiencies over 16.

With a record breaking 22 8 efficiency sunpower s panels convert more sunlight into usable electricity than almost any other commercially available panel. For example a solar panel that is 18 percent efficient will generate 50 percent more electricity than a panel that is 12 percent efficient. There are a few other solar panel manufacturers that produce premium efficiency panels which all clock in with efficiencies above 20.
