How to read and use the data
Gothenburg 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
Gothenburg's PVGIS specific yield is about 951 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, May 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 14:00-18:00 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 13.8 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 14:00-18:00. Never override frost protection, hygiene cycles or manufacturer limits.
Large loads
Avoid stacking appliances
A 3 kWp system scales to about 8.3 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 Gothenburg?
Using the same south-facing, 35-degree and 14% loss assumptions, the 5 kWp estimate is 13.8 kWh for Tuesday, September 1, 2026, with a scaled likely range of 9.0 kWh–17.4 kWh. This is a linear reference-system estimate, not a site survey.
What does 951 kWh/kWp mean for Gothenburg?
It means the PVGIS multi-year profile produces about 951 kWh in a typical year for each installed kWp under the reference assumptions. A 5 kWp system therefore scales to about 4,755 kWh in a typical year before site-specific adjustments.
Is the Gothenburg 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 Gothenburg?
Start with 14:00-18:00, 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.

What makes Gothenburg's solar profile different?The typical annual yield is about 951 kWh per installed kWp, ranking Gothenburg #5 of 7 modelled locations in Sweden. That is close to the median of the 7 Sweden locations in this dataset. May is typically the strongest month and December the weakest; the stronger month produces about 9.7 times as much.

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.
