Average Solar Panel Efficiency 2015

Solar panels have been consistently increasing in efficiency at about 5 annually since 2010.

Average solar panel efficiency 2015.

Average efficiency of solar panels generally the output of solar cells is measured by the amount of electricity they generate from sunlight. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. Typical solar panel efficiency ranges from 15 to 20 and the most efficient solar panels commercially availableare slightly above 22. 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.

Factors that affect solar panel efficiency. Sunpower nasdaq spwr currently makes the most efficient solar panel at 21 5 efficient versus 14 to 16 efficiency for a commodity panel. Not surprisingly more efficient panels cost more money. In simple terms solar panel efficiency can be described as the conversion rate from sunlight to electric power.

The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. Efficiency of a typical solar panel is around 15. This large jump in efficiency resulted in the power output of a standard size panel to increase from 250w up to 340w. For example an average silicon solar cell has an optimal efficiency rating of about 15.
