Poland Solar Forecast

Across 70 modelled locations in Poland, a standard 10 kWp south-facing system produces about 10,550 kWh in a typical year on average. Tomorrow's weather-based city forecasts range from 3.5 to 29.5 kWh for the same reference setup.

Poland solar outlook: tomorrow's city forecasts versus PVGIS yield

This page compares 70 modelled locations on one reference system. It is a city comparison tool, not a measurement or forecast of national solar generation.

Dated, weather-based

Tomorrow's forecast

For Friday, November 6, 2026, the 10 kWp city estimates average 15.0 kWh and span 3.5 kWh–29.5 kWh. That span is geographic variation between modelled cities, not an uncertainty interval or national forecast.

Multi-year climate baseline

PVGIS specific yield

The modelled cities average about 1,055 kWh/kWp in the PVGIS typical-year profile. Across the 10 kWp reference systems, typical annual output ranges from 10,030 to 11,035 kWh. June has the highest modelled average monthly output and December the lowest.

From forecast to a household plan

Battery, EV, heat pump and flexible loads

Choose the nearest representative city before scheduling equipment. A country average can frame the day, but a local forecast and the home's own demand determine usable surplus.

Battery

Use the nearest city, not the country mean

Open the closest city profile and preserve battery headroom around its strongest forecast window. The 3.5 kWh–29.5 kWh country spread shows why one national schedule would be unreliable.

Heat pump

Follow the local production window

Shift only discretionary water heating or pre-heating after checking the nearest city's strongest hours. Comfort, frost protection and hygiene controls take priority.

Large loads

Stagger flexible appliances

Country figures are daily energy, not simultaneous power. Use a city forecast and run flexible loads sequentially after allowing for base household consumption.

Local questions

Solar forecast FAQ

How much could a 5 kWp solar system produce tomorrow in Poland?

Across the 70 modelled locations, the 5 kWp estimates average 7.5 kWh for Friday, November 6, 2026 and span 1.8 kWh–14.8 kWh between cities. The spread is geographic, not a national uncertainty range.

Which modelled Poland location has the highest typical PV output?

Świdnica has the highest and Piła the lowest typical annual output among the 70 locations in this dataset. The comparison uses the same 10 kWp reference system and PVGIS climate profile.

Is the Poland city range a national solar forecast?

No. It is the minimum-to-maximum spread across 70 modelled city reference points. It does not aggregate installed solar systems, represent every local weather condition or provide a national generation total.

How should I use the Poland forecast for a battery, EV or heat pump?

Select the nearest city and use its strongest forecast hours, then subtract household base load and respect battery, charger and heat-pump operating limits. Use the country page to compare locations, not to control equipment directly.
