Across 4 modelled locations in Estonia, a standard 10 kWp south-facing system produces about 9,472 kWh in a typical year on average. Tomorrow's weather-based city forecasts range from 20.0 to 23.1 kWh for the same reference setup.

Tomorrow in Estonia
Using the same installation in every location isolates the effect of weather and geography. Choose a nearby city below for its dated forecast and seasonal profile, then adjust the location, panel capacity and roof settings in the solar forecast calculator.
Representative locations
Start with a location near your home. These are reference systems, not measurements of your roof or estimates of spare energy for a battery or car.
How to read and use the data
This page compares 4 modelled locations on one reference system. It is a city comparison tool, not a measurement or forecast of national solar generation.
Dated, weather-based
For Friday, November 6, 2026, the 10 kWp city estimates average 21.8 kWh and span 20.0 kWh–23.1 kWh. That span is geographic variation between modelled cities, not an uncertainty interval or national forecast.
Multi-year climate baseline
The modelled cities average about 947 kWh/kWp in the PVGIS typical-year profile. Across the 10 kWp reference systems, typical annual output ranges from 9,270 to 9,654 kWh. May has the highest modelled average monthly output and December the lowest.
3, 5 and 10 kWp reference systems
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
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
Open the closest city profile and preserve battery headroom around its strongest forecast window. The 20.0 kWh–23.1 kWh country spread shows why one national schedule would be unreliable.
EV
The 5 kWp country-average reference is 10.9 kWh before household use, but select a city because local estimates span 10.0 kWh–11.6 kWh.
Heat pump
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
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
Across the 4 modelled locations, the 5 kWp estimates average 10.9 kWh for Friday, November 6, 2026 and span 10.0 kWh–11.6 kWh between cities. The spread is geographic, not a national uncertainty range.
Pärnu has the highest and Narva the lowest typical annual output among the 4 locations in this dataset. The comparison uses the same 10 kWp reference system and PVGIS climate profile.
No. It is the minimum-to-maximum spread across 4 modelled city reference points. It does not aggregate installed solar systems, represent every local weather condition or provide a national generation total.
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.
Typical year
The bars average the 4 city reference points. Typical annual output ranges from about 9,270 to 9,654 kWh for the 10 kWp setup. Of the locations modelled, Pärnu has the highest typical annual output and Narva the lowest.
Typical monthly profiles use the European Commission JRC PVGIS multi-year climate series.
