Solar PV Analysis of Wilnis, Netherlands
Wilnis, Utrecht, a town in the Netherlands, presents a mixed picture for solar energy generation throughout the year. Located at latitude 52.1961 and longitude 4.8914 in the Northern Temperate Zone, Wilnis experiences significant seasonal variations in solar energy production.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Wilnis, Utrecht, with an average daily output of 5.42 kWh per kW of installed solar capacity. Spring follows closely, yielding 4.36 kWh/day. However, the performance drops considerably during autumn, producing only 2.14 kWh/day, and reaches its lowest point in winter with a mere 1.01 kWh/day.
These figures highlight the stark contrast between the warm and cold seasons, with summer generating more than five times the energy of winter. The extended daylight hours and higher sun angles during summer contribute significantly to this peak performance.
Optimal Panel Positioning
To maximize year-round solar energy production in Wilnis, Utrecht, fixed solar panels should be installed at a tilt angle of 44 degrees facing south. This angle is calculated to optimize energy capture across all seasons, considering the location's latitude and the Earth's elliptical orbit.
Environmental Considerations
While Wilnis's location is generally favorable for solar energy, there are some environmental factors that could impact production:
- Cloud cover: The Netherlands is known for its frequent cloudy weather, which can reduce solar efficiency.
- Rain and humidity: High levels of precipitation and humidity can affect panel performance and require more frequent cleaning.
To mitigate these issues, consider using high-efficiency panels designed for low-light conditions and implementing a regular cleaning schedule. Additionally, installing a robust mounting system can help panels withstand strong winds, which are common in the region.
In conclusion, while Wilnis experiences significant seasonal variations in solar energy production, proper panel positioning and maintenance can help maximize energy output throughout the year. The location is particularly well-suited for solar energy generation during spring and summer months, making it a viable option for supplementing energy needs, especially during these peak periods.

Solar output per kW of installed solar PV by season in Wilnis
Seasonal solar PV output for Latitude: 52.1961, Longitude: 4.8914 (Wilnis, Netherlands), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 44° South in Wilnis, Netherlands
To maximize your solar PV system's energy output in Wilnis, Netherlands (Lat/Long 52.1961, 4.8914) throughout the year, you should tilt your panels at an angle of 44° 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 Wilnis, Netherlands
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 Wilnis, Netherlands. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 44° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 36° South in Summer | 55° South in Autumn | 65° South in Winter | 44° 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.
Calculate solar panel row spacing in Wilnis, Netherlands
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 Wilnis, Netherlands.
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 Wilnis, Netherlands
The area around Wilnis, Netherlands, is characterized by a predominantly flat landscape typical of the western Netherlands. This region is part of the Dutch lowlands, which are known for their low elevation and minimal topographical variation. The terrain in and around Wilnis is largely comprised of polders, which are areas of reclaimed land that sit below sea level and are protected by dikes and drainage systems.
The topography of Wilnis and its surroundings features:
- Extensive areas of flat, open grassland used for agriculture and grazing
- Numerous drainage canals and small rivers crisscrossing the landscape
- Scattered patches of woodland and small forested areas
- Low-lying peat meadows, which are common in this part of the Netherlands
As for areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, several factors need to be considered:
1. Open, unobstructed land: The flat, open fields surrounding Wilnis could potentially be suitable for solar farms, as they receive ample sunlight without natural obstructions like hills or mountains.
2. Agricultural areas: Some of the less productive agricultural land in the region might be candidates for solar installations, though this would need to be balanced with the need to preserve farmland.
3. Industrial zones: Any nearby industrial areas or business parks with large, flat rooftops could be ideal for solar panel installation.
4. Reclaimed land: Some of the polders in the area, if not crucial for flood control or agriculture, might be considered for solar energy projects.
However, it's important to note that the Netherlands faces challenges in implementing large-scale solar projects due to its high population density and the competing demands for land use. Any solar PV development would need to be carefully planned and integrated with existing land uses, taking into account environmental concerns, local regulations, and the need to preserve the unique Dutch landscape.
