Solar panels in Kraków
A 6 kWp home system in Kraków is modelled to produce about 6,268 kWh a year, or 1,045 kWh per installed kWp, from PVGIS climate data at the city's coordinates. Kraków's municipal renewable energy programme funds up to 60 percent of eligible costs for residential buildings and dwellings, capped at 15,000 PLN for a PV installation and 9,000 PLN for electricity storage. Using 70% of the power at home instead of 30% moves payback from 16.0 to 8.8 years. No other city we cover in Poland has a higher yield than Kraków. Gdańsk gets 1,028 kWh per kWp. On our model, the system saves about PLN 3,165 in year one and pays back in 16.0 years.
Month by month in Kraków
Modelled output of a 6 kWp system at 35° facing south (towards the equator), from PVGIS climate data (PVGIS-SARAH3, 2005 to 2023).
| Month | kWh | Share of year |
|---|---|---|
| January | 251 | 4.0% |
| February | 329 | 5.2% |
| March | 556 | 8.9% |
| April | 669 | 10.7% |
| May | 712 | 11.4% |
| June | 734 | 11.7% |
| July | 762 | 12.2% |
| August | 714 | 11.4% |
| September | 591 | 9.4% |
| October | 464 | 7.4% |
| November | 263 | 4.2% |
| December | 222 | 3.5% |
- Best month: July (762 kWh). Weakest: December (222 kWh), a 3.4x difference.
- June, July, August produce 35.3% of the year; January, November, December produce 11.7%.
- Year-to-year variation: about 293 kWh (4.7%, one standard deviation).
- Sunlight reaching the panels: 1,354 kWh per m² a year.

Kraków renewable energy grant (PV and storage)
Kraków's municipal renewable energy programme funds up to 60 percent of eligible costs for residential buildings and dwellings, capped at 15,000 PLN for a PV installation and 9,000 PLN for electricity storage. The 2026 call ran from 23 March to 24 April 2026, and applications outside that window are rejected.

How Kraków compares
Kraków ranks 1 of 3 for yield among the cities we model in Poland, and 27 of 41 across every country on Solar Figures. Within one country the prices are the same, so a payback gap between these cities comes from sunshine alone.
| City | kWh per kWp / yr | Payback (PLN) |
|---|---|---|
| Kraków | 1,045 | 16.0 yrs |
| Gdańsk | 1,028 | 16.2 yrs |
| Warsaw | 1,014 | 16.5 yrs |
| National reference point (country page) | 1,014 | 16.5 yrs |
Closest yield abroad: Berlin (1,022 kWh per kWp), Brussels (1,009 kWh per kWp), Antwerp (1,005 kWh per kWp).
What moves the payback in Kraków
Power you use yourself is worth the retail price (PLN 1.00 per kWh); power you export earns PLN 0.30. So the share you use at home, by running appliances in daylight or adding a battery, changes the payback. The system cost stays the same in every row (a battery would add to it).
| Used at home | Year-1 savings | Payback |
|---|---|---|
| 20% | PLN 2,730 | 19.2 yrs |
| 30% (our default) | PLN 3,165 | 16.0 yrs |
| 50% | PLN 4,033 | 10.9 yrs |
| 70% | PLN 4,902 | 8.8 yrs |
- Net system cost after incentives: PLN 42,000 for 6 kWp.
- Incentive modelled: No reliable standalone PV grant in 2026 -- Moj Prad closed Sept 2025; KPO replacement funds PV only when BUNDLED with a battery, in short budget-limited rounds..
- 25-year net savings at our default: PLN 72,135.
Best panel angle in Kraków
At latitude 50.06°N, PVGIS finds the fixed tilt and direction that maximise yearly output. Our figures use a common 35° roof; the table shows what the optimum adds.
| Setup | Tilt | Facing | kWh per kWp / yr |
|---|---|---|---|
| Standard roof (used on this page) | 35° | south | 1,045 |
| PVGIS optimum | 39° | south (179°) | 1,047 |
The optimum adds 0.2% a year over the standard roof in Kraków. Most of a roof's value comes from its direction: a roof facing away from the equator loses far more than a few degrees of tilt.
