Solar power plant in Krakow, Poland: yield, tilt angle and row spacing
Krakow: 1,085 kWh per kWp a year at the optimal tilt of 39°, 1° east of south (PVGIS). 1.9% above the median of the main cities of Poland (1,065). #16 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 2.6% less here.
Krakow is in Lesser Poland Voivodeship. Population 816,614 (GeoNames). 219 m above sea level. 252 km away: Warsaw, the nearest bigger city, 1,053 kWh/kWp — 3.1% more here. 12.70 m between rows, pitch 16.42 m, GCR 0.29 (latitude 50.1°).

Yield by month
July: 130 kWh/kWp, December: 40 — 3.3 times less.
December: 40 against the median of 32 for the main cities of Poland, 25.0% more.

Fixed tilt facing south
What a table yields at another tilt than the optimal 39° — for roofs and frames with a standard slope.
| Tilt | A year | Against the optimum |

| 39° (optimum) | 1,085 | — |
| 15° | 1,012 | −6.7% |
| 30° | 1,074 | −1.1% |

Snow and wind loads
Snow and wind loads for a site in Poland follow PN-EN 1991-1-3 (snow) and PN-EN 1991-1-4 (wind) with the Polish National Annex (NA). Solispec computes loads by the Ukrainian DBN V.1.2-2 only, so this page shows no snow or wind values for Poland: enter the characteristic values from these documents in the designer’s «Own snow S0» and «Own wind W0» fields.
The frame calculation for such a site is preliminary: before installation it must be checked by an engineer who works to the country’s standards.
