Solar potential in Milan
This estimate represents one coordinate near the city center, not every roof or neighborhood.

PV output is estimated electricity from 1 kWp of installed solar panels. Irradiation is sunlight energy received per square meter on the optimally tilted panel plane; it is not electricity.
For a 5 kWp system, multiply the electricity values by five. This simple scaling does not account for roof-specific shading or equipment constraints.
Compared with the sampled-city benchmark: -4.8% (1,425kWh/kWp/year). These figures are the unweighted mean of the city locations listed below, not a national average. Two urban points do not represent an entire country, its roofs or its solar installations.
Monthly solar irradiation and PV output
Highest-output month: July · 156kWh/kWp/month. Lowest-output month: December · 63.4kWh/kWp/month.

Data and methodology
PVGIS 5.3 (European Commission Joint Research Centre), crystalline silicon, fixed free-standing installation, 1 kWp, 14% system losses, equator-facing panels with optimized tilt and the terrain horizon. Long-term climate estimates are not a forecast or a roof survey. Nearby buildings, trees, roof constraints, snow and local conditions can change actual output.
