How to Improve Solar Panel Efficiency? You Must Know

What is Photovoltaic Efficiency?

If the output power is divided by the input power and multiplied by 100 it is called efficiency (output/input * 100). In short, the ratio of output power to input power multiplied by 100 is called efficiency. However, solar cell efficiency is considered as a low efficient device. It is because the solar panel output power is lower than the input power. But solar panel or PV panel efficiency can be increased by some special technique. However, let’s see how to improve solar panel efficiency to get more output.
