How to read and use the data
Piła solar forecast: daily weather versus long-term PV yield
The daily and annual figures answer different questions. Use the dated forecast to plan tomorrow, and the PVGIS specific yield to compare locations or estimate a typical year.
Multi-year climate baseline
PVGIS specific yield
Piła's PVGIS specific yield is about 1,003 kWh/kWp per year. It is a multi-year climate benchmark, not a prediction for tomorrow or for this calendar year. In the PVGIS profile, June is typically the strongest month and December the weakest.

Linear reference scaling only: south-facing, 35° tilt and 14% system losses. It does not resize inverter clipping, shade or local roof constraints.
From forecast to a household plan
Battery, EV, heat pump and flexible loads
Treat the forecast as a gross solar-energy budget before household base load and conversion losses. The numbers support scheduling; they do not guarantee surplus.
Battery
Keep room for the solar window
Use 12:00-16:00 as the first candidate charging window. Battery state of charge, reserve settings and inverter limits still decide how much can be stored.
EV
Compare the charge with the 5 kWp budget
The scaled 5 kWp estimate is 15.2 kWh before household use. Compare the remainder after base load with the planned EV charge and stagger charging if needed.
Heat pump
Shift only flexible thermal demand
If comfort controls allow it, place discretionary hot-water heating or pre-heating inside 12:00-16:00. Never override frost protection, hygiene cycles or manufacturer limits.
Large loads
Avoid stacking appliances
A 3 kWp system scales to about 9.1 kWh for the day before household use. Run flexible loads sequentially during the strongest hours rather than assuming all forecast energy is simultaneous power.
Local questions
Solar forecast FAQ
How much could a 5 kWp solar system produce tomorrow in Piła?
Using the same south-facing, 35-degree and 14% loss assumptions, the 5 kWp estimate is 15.2 kWh for Monday, October 5, 2026, with a scaled likely range of 10.7 kWh–19.0 kWh. This is a linear reference-system estimate, not a site survey.
What does 1,003 kWh/kWp mean for Piła?
It means the PVGIS multi-year profile produces about 1,003 kWh in a typical year for each installed kWp under the reference assumptions. A 5 kWp system therefore scales to about 5,015 kWh in a typical year before site-specific adjustments.
Is the Piła forecast the same as the PVGIS annual estimate?
No. Tomorrow's forecast uses dated weather and an uncertainty band for one day. The PVGIS figure is a multi-year climate-based specific yield used for typical monthly and annual comparisons.
When should a battery, EV or heat pump use solar in Piła?
Start with 12:00-16:00, then check household base load, battery headroom, EV energy required and heat-pump safety or comfort constraints. The forecast estimates daily energy, not guaranteed instantaneous surplus.
Typical year
Solar production month by month in Piła
A standard 10 kWp system produces about 10,030 kWh in a typical year at this location. Monthly averages show seasonality; they are not a forecast for a specific year.

Method and data
Every city uses a 10 kWp system facing south at 35 degrees with 14% system losses. Tomorrow's figure combines hourly weather with GridPassport's PV production and uncertainty model. The monthly profile uses the European Commission JRC PVGIS multi-year climate series. Roof direction, shade, snow, dirt, inverter clipping and local weather can change real output.
