How we worked this out
We used daily shortwave radiation data for Armagh from Open-Meteo and applied the standard PV yield model:
energy = radiation × system kWp × performance ratio.
The performance ratio is 0.78 (accounts for inverter and temperature losses, orientation and soiling).
Electricity is valued at 33.5p/kWh, the Power NI standard credit tariff.
Figures are an estimate based on forecast conditions and a representative install. Actual generation varies with roof orientation, shading and hardware.
