The average efficiency of solar panels falls between the 17 to 19 percent efficiency range.
Efficiency of photovoltaic solar panels.
It is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell.
It is true that solar cell efficiency directly affects the solar panel efficiency.
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 highest efficiency solar panels on the market today can reach almost 23 percent efficiency.
Most solar panels are between 15 and 20 efficient with outliers on either side of the range.
High quality solar panels can exceed 22 efficiency in some cases and almost reach 23 but the majority of photovoltaic panels available are not above 20 efficiency.
