Banna is a 13.7 MW solar power plant in Piedmont, Italy. Based on its capacity (estimated), it can supply roughly 5.8k homes (estimated). It ranks #301 of 489 Italy power plants by installed capacity. Commissioned in 2017, it is around 9 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 16.9% of Italy's electricity; the national grid averages 285 gCO₂/kWh (48.8% low-carbon) (2025).

Capacity provenance
The public capacity above is the current source-record value. A 2026 tracker candidate lists 14 MW for Banna solar project, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

In context: how this plant compares
At 13.7 MW, Banna is well above the median solar plant in Italy (6 MW). Technically it is described as Assumed PV. Solar PV converts sunlight directly into electricity with no moving parts or fuel; output varies by time of day and weather, so it pairs with storage or flexible backup.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.
Key facts
- Share of Italy solar capacity
- 0.7% of 1,975 MW across 223 plants in this dataset

Local climate & thermal context
This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 44.9°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 6% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.
Climate heat-demand index: 48/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 0.0% at warm-season highs here (estimate).
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
Site climate & environmental severity
This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
How it compares & nearby plants
The #37 largest solar power plant of 223 in Italy by capacity.
