Solar production through the year
Kilowatt-hours a 1 kWp system produces each month at the optimal angle.
Here the best month produces more than twenty times what the worst one does, which is why a system sized to cover a year's use still leaves you buying electricity in winter.
Where these numbers come from
Each bar is what PVGIS models a 1 kWp system producing in that month at this city's exact coordinates, tilted at the angle that suits the location best. Nothing is interpolated between cities: every city here is queried separately and the twelve monthly figures are stored as they arrive.
twelve months added together = 898 kWh per kWp a year
To get the output of a real array, multiply by its size in kWp. A typical domestic system is 4 to 6 kWp. The figure already allows for losses in the cabling and the inverter, and losses from heat, and it assumes nothing shades the roof, which no model can know.

Both calculators start from this city's figures, so you only have to describe yourself: how far you drive, how much electricity you use, and what a system would cost you.
Solar figures are long-term averages from PVGIS and will not match any single year.
