Question

How the module efficiency is calculated?

Answer 1

Explanation:

For example if you have a solar module that is 1 meter long by 1 meter wide and produces 1000 watts, this would be a 100% efficient solar module as all of the available sunlight (1000 watts per square meter (w/m2) is converted to electrical output. ...

Answer 2

Answer:

To calculate the efficiency of your panel, just multiply the amount of sunlight that hits the earth's surface in your area (known as the “incident radiation flux”) by the area of your panel (measured in square meters).
