The location in Genk, Flanders, Belgium, situated at latitude 50.9671 and longitude 5.5003, presents a mixed picture for year-round solar PV energy generation. This Northern Temperate Zone location experiences significant seasonal variations in solar output, which impacts the overall efficiency of solar installations.
Seasonal Solar Performance
Solar energy production in Genk varies considerably throughout the year. Summer stands out as the most productive season, with an average daily output of 5.25 kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.63 kWh per day. However, the output drops significantly in autumn to 2.46 kWh per day, and winter sees the lowest production at just 1.18 kWh per day.
These figures indicate that Genk's location is most ideal for solar energy generation during the spring and summer months, typically from April to September. During this period, longer daylight hours and higher sun angles contribute to increased solar panel efficiency.
Optimal Panel Installation
To maximize year-round solar production at this location, fixed solar panels should be installed at a tilt angle of 43 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun positions across seasons.
Environmental and Weather Factors
Several factors in Genk may impact solar energy production:
- Cloud cover: Belgium's climate is known for frequent cloud cover, which can reduce solar radiation reaching the panels.
- Rainfall: The region experiences significant rainfall, which may temporarily reduce panel efficiency.
- Snow: Winter snowfall can cover panels, impeding energy production.
To mitigate these factors, consider the following preventative measures:
- Install panels at the optimal angle to promote natural cleaning by rain and snow sliding off.
- Use self-cleaning panel technologies or schedule regular cleaning.
- Implement snow removal strategies for winter months.
- Consider microinverters or power optimizers to minimize the impact of partial shading.
While Genk's location presents challenges for year-round solar energy production, particularly in winter, proper installation techniques and maintenance can help maximize output during the more favorable months, making solar PV a viable renewable energy option for the area.

Solar output per kW of installed solar PV by season in Genk
Seasonal solar PV output for Latitude: 50.9671, Longitude: 5.5003 (Genk, Belgium), 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 43° South in Genk, Belgium
To maximize your solar PV system's energy output in Genk, Belgium (Lat/Long 50.9671, 5.5003) 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 Genk, Belgium
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 Genk, Belgium. 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 | 54° 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.
Calculate solar panel row spacing in Genk, Belgium
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 Genk, Belgium.
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 Genk, Belgium
The topography around Genk, Belgium, situated at latitude 50.9671 and longitude 5.5003, is characterized by a relatively flat landscape with gentle undulations. This area is part of the Campine region, known for its sandy soil and heathlands. The terrain is generally low-lying, with elevations ranging from about 50 to 100 meters above sea level. The landscape is a mix of urban development, industrial areas, and patches of natural vegetation. To the north and east of Genk, the land is slightly more elevated, forming part of the Campine Plateau. This area features a mix of forests, agricultural lands, and some remnants of the original heathland ecosystem. To the south and west, the terrain gradually slopes down towards the Demer Valley, where the land becomes more marshy and prone to flooding. The region around Genk has been significantly altered by human activity, particularly due to coal mining in the past. This has resulted in some artificial hills, known as slag heaps, which are now mostly covered with vegetation and blend into the landscape. These former mining sites have been repurposed for various uses, including nature reserves and recreational areas.
Areas Suitable for Large-Scale Solar PV
When considering areas near Genk that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would have ample open space, minimal shading, and good access to existing infrastructure. One promising area for solar PV development would be the former mining sites and industrial areas around Genk. These brownfield sites often have large, open spaces that are already connected to the power grid. The relatively flat terrain of these areas would make installation and maintenance of solar panels easier and more cost-effective. Agricultural lands to the north and east of Genk could also be suitable for solar PV installations, particularly if implemented as part of agrivoltaic systems that combine solar energy production with crop cultivation. However, this would need to be balanced with the need to preserve productive farmland. The Campine Plateau area, with its slightly higher elevation and open landscapes, could potentially offer good conditions for solar energy production. However, care would need to be taken to avoid areas of ecological importance, such as protected heathlands and forests. It's worth noting that while the topography around Genk is generally favorable for solar PV, the region's climate, with its relatively high number of cloudy days, may impact the overall efficiency of solar installations. Therefore, careful site selection and system design would be crucial to maximize energy production in this area.Belgium solar PV Stats as a country
