What is the net energy yield of solar energy?

The yield is the annual amount of energy that was generated per kWp installed.

Explanation:

Net energy yield is the amount of energy got during the process of collecting the energy source.

This process represents the total amount of energy that was gained while collecting the source after subtracting the amount of energy expended to utilize it.

The total amount of wattage on the panel divided by net number and multiplicated with 100 gives the efficiency rating.
