Efficiency Of Photovoltaic Solar Panels

It is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell.

Efficiency of photovoltaic solar panels.

Solar cell efficiency refers to the ratio of the power output of a solar cell to its power input while considering its surface area. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. If a solar panel has 20 percent efficiency that means it s capable of converting 20 percent of the sunshine hitting it into electricity. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency.

For example a solar panel with 20 efficiency and an area of 1 m 2 will produce 200 kwh yr at standard test conditions but it can produce more when the sun is high in the sky and will produce less in cloudy conditions or when the sun is low in the sky. Most solar panels are between 15 and 20 efficient with outliers on either side of the range.
