The average efficiency of solar panels falls between the 17 to 19 percent efficiency range.
High efficiency light solar panels.
Stion is a leading producer of high efficiency thin film solar panels based on state of the art materials advanced technology and high quality production processes.
Most solar panels sold in 2020 have efficiencies between 15 and 20 according to the national renewable energy laboratory nrel.
Some solar panels in the market have efficiencies over 20 these are known as high efficiency 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.
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.
Their panels provide up to 50 better performance in shaded conditions compared to mono and polycrystalline silicon pv panels.
The highest efficiency solar panels on the market today can reach almost 23 percent efficiency.
