Energy Efficiency Of Solar Panels

Solar panel efficiency is a measure of the amount of solar energy irradiation which falls on a panel surface and is converted into electricity.

Energy efficiency of solar panels. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity. So if a solar panel has an efficiency rating of 15 that means 15 of the sunlight that hits the solar panels will be converted into electricity. The conversion efficiency of a photovoltaic pv cell or solar cell is the percentage of the solar energy shining on a pv device that is converted into usable electricity.

Most solar panels are between 15 and 20 efficient with outliers on either side of the range. High quality solar panels can exceed 22 efficiency in some cases and almost reach 23 but the majority of photovoltaic panels available are not above 20 efficiency. Improving this conversion efficiency is a key goal of research and helps make pv technologies cost competitive with conventional sources of energy. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range.

For example a solar panel with 20 efficiency and an area of 1 m2 will produce 200 kwh yr at standard test conditions but it can produce more when the sun is high in the sky and will pro. What is solar panel efficiency. If a solar panel has 20 percent efficiency that means it s capable of converting 20 percent of the sunshine hitting it into electricity.
