How efficient solar panel.

Solar panels have been consistently increasing in efficiency at about 5 annually since 2010. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. 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. 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.

Factors that affect solar panel efficiency. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity. Solar panel efficiency is one of the most important parameters when you are considering to install a pv system.

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. This large jump in efficiency resulted in the power output of a standard size. 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.
