Average Solar Panel Efficiency 2015

This large jump in efficiency resulted in the power output of a standard size panel to increase from 250w up to 340w.

Average solar panel efficiency 2015.

Efficiency of a typical solar panel is around 15. Solar panels have been consistently increasing in efficiency at about 5 annually since 2010. If the efficiency of solar panels is high you will need less space to produce enough energy. 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.

The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. Some laboratory prototypes have reached efficiency values over 40 but they are still very expensive and not viable for commercial use. The average efficiency of solar panels is typically determined by measuring the amount of energy that individual solar cells are able to convert into usable power. For example an average silicon solar cell has an optimal efficiency rating of about 15.

Factors that affect solar panel efficiency. Typical solar panel efficiency ranges from 15 to 20 and the most efficient solar panels commercially availableare slightly above 22. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. In simple terms solar panel efficiency can be described as the conversion rate from sunlight to electric power.
