Efficiency Rating Solar Panels

In other words the efficiency value that we can find on the datasheet of a solar panel represents the ability of the module to convert sunlight into electricity according to its size.

Efficiency rating solar panels.

Most solar panels are between 15 and 20 efficient with outliers on either side of the range. The graphic below shows how dramatically solar panel performance has improved over time. 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 most efficient solar panels commercially available today have solar panel efficiency just under 23.

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 average efficiency of solar panels falls between the 17 to 19 percent efficiency range. A higher solar panel efficiency rating means a panel will produce more kilowatt hours of energy per watt of power capacity. 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.

Simply put solar panel efficiency is referred to the ratio of peak power compared to the amount of sunlight that arrives at the solar cells of the module. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency.
