Solar PV System Energy Production Calculator
This calculator estimates the annual electricity generation of a grid-connected photovoltaic system. It accounts for efficiency losses to provide a realistic energy yield estimate.
Enter the System Power, Peak Sun Hours, and Performance Ratio to determine the solar energy produced by the PV System

This calculator provides estimated energy production values based on installed system capacity, solar data, and typical system performance, which can be intended for planning, feasibility assessment, and preliminary analysis purposes.
Example:
For a 5 kW PV system receiving 4.5 hours of peak sunlight and a performance ratio of 0.75 (75%),
Annual Energy Production = 5 x 4.5 x 0.75 x 365 = 6159.375 kWh
Annual Specific Yield = 6159.375 / 5 = 1231.875 kWh/kWp/year
Capacity Factor = (1231.875/ (365 x 24)) x 100 = 14.06 %
Total System Loss = (1-0.75) x 100 = 25 %
