How Efficient Solar Panel

Factors that affect solar panel efficiency.

How efficient solar panel.

Solar panel efficiency is a measure of the amount of solar energy irradiation which falls on a panel surface and is converted into electricity 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. Solar panel efficiency is a measurement of a solar panel s ability to convert sunlight into usable electricity. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. Solar panels have been consistently increasing in efficiency at about 5 annually since 2010.

This large jump in efficiency resulted in the power output of a standard size. Given the same amount of sunlight shining for the same duration of time on two solar panels with different efficiency ratings the more efficient panel will produce more electricity than the less efficient panel. The efficiency of the solar cells used in a photovoltaic system in combination with latitude and climate determines the annual energy output of the system for example a solar panel with 20 efficiency and an area of 1 m 2 will produce 200. Solar cell efficiency refers to the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell.

The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. This factor is not only a reference of quality between a premium solar panel and an average module but it is also a parameter that defines how much energy can be produced. Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity.
