Dated, weather-based
Tomorrow's forecast
For Friday, November 6, 2026, the 10 kWp city estimates average 30.9 kWh and span 8.8 kWh–37.6 kWh. That span is geographic variation between modelled cities, not an uncertainty interval or national forecast.
Slovakia Solar Forecast
Across 25 modelled locations in Slovakia, a standard 10 kWp south-facing system produces about 11,603 kWh in a typical year on average. Tomorrow's weather-based city forecasts range from 8.8 to 37.6 kWh for the same reference setup.

How to read and use the data
Slovakia solar outlook: tomorrow's city forecasts versus PVGIS yield
This page compares 25 modelled locations on one reference system. It is a city comparison tool, not a measurement or forecast of national solar generation.
Multi-year climate baseline
PVGIS specific yield
The modelled cities average about 1,160 kWh/kWp in the PVGIS typical-year profile. Across the 10 kWp reference systems, typical annual output ranges from 10,817 to 12,345 kWh. July 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 8.8 kWh–37.6 kWh country spread shows why one national schedule would be unreliable.
EV
Size the charge against local energy
The 5 kWp country-average reference is 15.5 kWh before household use, but select a city because local estimates span 4.4 kWh–18.8 kWh.
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 Slovakia?
Across the 25 modelled locations, the 5 kWp estimates average 15.5 kWh for Friday, November 6, 2026 and span 4.4 kWh–18.8 kWh between cities. The spread is geographic, not a national uncertainty range.
Which modelled Slovakia location has the highest typical PV output?
Nové Zámky has the highest and Bardejov the lowest typical annual output among the 25 locations in this dataset. The comparison uses the same 10 kWp reference system and PVGIS climate profile.
Is the Slovakia city range a national solar forecast?
No. It is the minimum-to-maximum spread across 25 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 Slovakia 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.
Typical year
Monthly solar production across Slovakia
The bars average the 25 city reference points. Typical annual output ranges from about 10,817 to 12,345 kWh for the 10 kWp setup. Of the locations modelled, Nové Zámky has the highest typical annual output and Bardejov the lowest.
