Zgorzelec, Lower Silesia, Poland, situated at latitude 51.1449 and longitude 15.0125, presents a mixed scenario for solar PV energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar energy production.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 5.21 kWh per day for each kW of installed solar capacity. Spring follows as the second-best season, generating 3.93 kWh daily. Autumn sees a considerable drop to 2.20 kWh per day, while winter performance plummets to a mere 0.94 kWh daily.
These figures highlight the stark contrast between summer and winter production, with summer yielding over five times more energy than winter. The shoulder seasons of spring and autumn offer moderate production levels, bridging the gap between the extremes.
Optimal Panel Positioning
To maximize year-round solar energy production in Zgorzelec, Lower Silesia, fixed solar panels should be tilted at a 43-degree angle facing south. This optimal angle takes into account the location's latitude and seasonal sun positions, ensuring the best possible energy capture across all seasons.
Environmental and Weather Considerations
Zgorzelec's climate presents some challenges for solar energy production. The region experiences cloudy weather, particularly during autumn and winter, which can significantly reduce solar panel efficiency. Additionally, snowfall in winter may cover panels, further diminishing their output.
To mitigate these issues, consider the following preventative measures:
- Install panels at the recommended 43-degree tilt to promote snow sliding off and maximize sun exposure.
- Use high-efficiency panels designed to perform well in low-light conditions.
- Implement a regular cleaning schedule, especially after snowfall or during periods of high air pollution.
Despite these challenges, Zgorzelec's location can still be viable for solar energy production, particularly from late spring through early autumn. The long summer days and high sun angle during this period provide excellent conditions for solar power generation, making it an attractive option for supplementing energy needs, especially when combined with other renewable sources or energy storage solutions.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 43° South in Zgorzelec, Poland
To maximize your solar PV system's energy output in Zgorzelec, Poland (Lat/Long 51.1449, 15.0125) throughout the year, you should tilt your panels at an angle of 43° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Zgorzelec, Poland
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Zgorzelec, Poland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 43° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 34° South in Summer | 53° South in Autumn | 64° South in Winter | 43° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.

We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Zgorzelec, Poland.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Zgorzelec, Poland
The landscape surrounding Zgorzelec, Poland, is characterized by a diverse and gently undulating topography. Located in the southwestern part of the country, near the border with Germany, this area sits within the North European Plain. The terrain is primarily composed of rolling hills, shallow valleys, and expansive flatlands, creating a picturesque blend of natural features. To the south and southwest of Zgorzelec, the land gradually rises towards the foothills of the Izerskie Mountains, part of the larger Sudetes mountain range. This transition from lowlands to highlands creates a varied landscape with subtle elevation changes. The nearby Nysa Łużycka River, which forms the border between Poland and Germany, has carved a shallow valley through the region, adding to its topographical diversity.
Potential Areas for Large-Scale Solar PV
When considering suitable locations for large-scale solar photovoltaic (PV) installations near Zgorzelec, several factors come into play. The most promising areas would be those with relatively flat or gently sloping terrain, minimal shading from natural or man-made structures, and good access to existing infrastructure. The expansive agricultural lands to the north and northeast of Zgorzelec present favorable conditions for solar PV development. These areas often feature open fields with few obstructions, allowing for maximum sun exposure throughout the day. The gentle slopes in this region can also be advantageous, as they can be oriented to optimize solar panel placement for increased efficiency. Another potentially suitable area lies to the east and southeast of Zgorzelec, where the landscape transitions into more open, plateau-like terrain. These elevated flatlands could provide ideal conditions for solar farms, with their unobstructed views of the sky and minimal risk of flooding. It's important to note that while the topography around Zgorzelec offers several promising locations for solar PV installations, other factors such as local zoning regulations, environmental considerations, and grid connection capabilities would need to be carefully evaluated before embarking on any large-scale solar projects in the region.Poland solar PV Stats as a country
