Solar Generation Calculator

Solar Panels generate electricity based on the amount of sunlight that strikes them. There are seasonal fluctuations as daylight hours change.

Calculate your estimated solar energy production per month with this simple tool.

Enter your annual generation figure or estimated figure from your MCS certificate into the box below and click "Calculate". You will see a breakdown of estimated generation across the year. If you don't already have Solar PV, you could enter the UK average generation for a 4kW system, 3500kWh.

This tool is provided as a guide based on seasonal averages and your actual generation may differ.


You could optimise the amount of solar energy you generate by upgrading to a SolarEdge inverter with Power Optimisers.
