Effcieny design solar panels.

The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. Solar panel efficiency is a measure of the amount of solar energy irradiation which falls on a panel surface and is converted into electricity. Sunpower panels are known for being the most efficient solar panel brand available on the market. Due to the many recent advances in solar cell technology over the last 5 years average panel conversion efficiency has increased from 15 to 20.

If a solar panel has 20 percent efficiency that means it s capable of converting 20 percent of the sunshine hitting it into electricity. Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity. Solar panels are slightly less efficient at energy conversion per surface area than individual cells because of inevitable inactive areas in the assembly and cell to cell variations in performance. So if a solar panel has an efficiency rating of 15 that means 15 of the sunlight that hits the solar panels will be converted into electricity.

The highest efficiency solar panels on the market today can reach almost 23 percent efficiency.
