Average Solar Panel Efficiency 2015

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

Average solar panel efficiency 2015.

Efficiency of a typical solar panel is around 15. Some laboratory prototypes have reached efficiency values over 40 but they are still very expensive and not viable for commercial use. In simple terms solar panel efficiency can be described as the conversion rate from sunlight to electric power. For example an average silicon solar cell has an optimal efficiency rating of about 15.

The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. Sunpower nasdaq spwr currently makes the most efficient solar panel at 21 5 efficient versus 14 to 16 efficiency for a commodity panel. 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. Not surprisingly more efficient panels cost more money.

The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. Average efficiency of solar panels generally the output of solar cells is measured by the amount of electricity they generate from sunlight. If the efficiency of solar panels is high you will need less space to produce enough energy. Typical solar panel efficiency ranges from 15 to 20 and the most efficient solar panels commercially availableare slightly above 22.
