Average Solar Panel Efficiency 2015
The average efficiency of solar panels falls between the 17 to 19 percent efficiency range.
Average solar panel efficiency 2015. Sunpower nasdaq spwr currently makes the most efficient solar panel at 21 5 efficient versus 14 to 16 efficiency for a commodity panel. If the efficiency of solar panels is high you will need less space to produce enough energy. In simple terms solar panel efficiency can be described as the conversion rate from sunlight to electric power. 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.
Solar panels have been consistently increasing in efficiency at about 5 annually since 2010. Average efficiency of solar panels generally the output of solar cells is measured by the amount of electricity they generate from sunlight. Not surprisingly more efficient panels cost more money. Efficiency of a typical solar panel is around 15.
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. Typical solar panel efficiency ranges from 15 to 20 and the most efficient solar panels commercially availableare slightly above 22. Factors that affect solar panel efficiency. For example an average silicon solar cell has an optimal efficiency rating of about 15.
