Solar Panel Efficiency Rating

Because one high efficiency panel can generate more electricity than a similarly sized panel with a standard efficiency rating efficiency is particularly important if you have limited roof space and large energy bills.

Solar panel efficiency rating.

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. 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. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency.

The best solar panels available on the market today are sunpower s a series residential solar panels which are 22 8 efficient at their maximum. 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. Factors that affect solar panel efficiency. 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.

Solar panels have been consistently increasing in efficiency at about 5 annually since 2010. 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. The higher the efficiency rating the more sunlight your. A higher efficiency rating is better because it means that your solar panel is able to convert more of the sunlight it captures into electricity.

It s possible that certain information such as solar panel efficiency may not ever leave the warehouse. A higher solar panel efficiency rating means a panel will produce more kilowatt hours of energy per watt of power capacity. What you need to know. These days the average efficiency of a solar panel is about 18 7 percent.

Of course one obvious answer is that not all companies can necessarily boast a 22 efficiency rating let alone a 21 5. The efficiency of a solar panel simply describes how well it turns sunlight into usable electricity. They know but don t want to tell.
