Beaufays, Wallonia, Belgium, situated at latitude 50.5593 and longitude 5.6353, offers varied solar energy generation potential throughout the year. Located in the Northern Temperate Zone, this location experiences significant seasonal fluctuations in solar PV output.
Seasonal Solar Production
Solar panels in Beaufays produce their highest output during summer months, generating approximately 5.20 kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 4.57 kWh/day per kW installed. Production decreases substantially during autumn to 2.40 kWh/day, while winter sees the lowest generation at just 1.13 kWh/day per kW installed.
This pattern creates a significant contrast between summer and winter production, with summer yielding nearly five times the energy of winter months. The shoulder seasons of spring and autumn serve as transition periods, with spring performance approaching summer levels.
Optimal Panel Installation
For fixed solar panel installations in Beaufays, Wallonia, the ideal tilt angle to maximize year-round energy production is 43 degrees facing south. This specific angle has been calculated by weighting daily optimal angles according to solar potential throughout the year, accounting for Earth's elliptical orbit and the location's latitude.
Environmental and Weather Considerations
Several factors may impact solar production in this Belgian location:
- Cloud cover and precipitation are significant in Belgium's climate, particularly during autumn and winter months, contributing to the lower production figures during these seasons.
- Snow accumulation can temporarily reduce panel efficiency during winter months if not cleared.
- Morning fog, common in this region, may delay peak production during early hours.
- Tree coverage and surrounding buildings could create shading issues at this specific location.
Recommended Preventative Measures
To maximize solar energy production in Beaufays, Wallonia, consider implementing these strategies:
- Install panels with anti-reflective coatings to improve light absorption during cloudy conditions.
- Consider self-cleaning panel technologies or implement a regular cleaning schedule to address snow, dust, and pollen accumulation.
- Conduct a thorough shade analysis before installation to avoid potential obstructions.
- For larger installations, snow sensors and removal systems may be worthwhile investments given the winter conditions.
- Consider microinverters or power optimizers to minimize production losses when some panels are partially shaded or covered.
While Beaufays isn't ideal for year-round consistent solar production due to its significant seasonal variations, proper system design can still make solar PV a viable energy source, particularly when optimized to capture the substantial spring and summer production potential.

Ideally tilt fixed solar panels 43° South in Beaufays, Belgium
To maximize your solar PV system's energy output in Beaufays, Belgium (Lat/Long 50.5593, 5.6353) 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 Beaufays, 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 Beaufays, 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 | 53° South in Autumn | 63° 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 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 Beaufays, Belgium
Topography of Beaufays
Beaufays is situated in the eastern part of Belgium, nestled within the picturesque region of Wallonia. The topography around Beaufays is characterized by rolling hills, gentle valleys, and modest elevations that form part of the Ardennes foothills. This area features a varied landscape with elevations generally ranging between 200 and 300 meters above sea level. The terrain around Beaufays displays a mix of forested areas and open agricultural land. The region is marked by numerous small streams and rivers that have carved shallow valleys throughout the landscape over millennia. The Vesdre River valley lies to the north, while the Ourthe River flows to the west, both contributing to the undulating nature of the topography.Surrounding Landscape Features
Moving outward from Beaufays, the landscape becomes more pronounced in its relief, particularly toward the southeast where the true Ardennes begin. This transition is marked by increasingly steep slopes and deeper valleys. To the north and west, the terrain gradually flattens as it approaches the Meuse Valley and the city of Liège. The area features a mosaic of land uses, with deciduous forests covering many of the steeper slopes and hilltops. Between these wooded areas lie agricultural fields and meadows, creating a patchwork appearance typical of the Belgian countryside. Small villages and hamlets dot the landscape, often situated in valley bottoms or along ridgelines.Solar PV Suitability in the Region
When considering locations for large-scale solar photovoltaic installations near Beaufays, several factors related to the topography come into play. The most suitable areas would be: The relatively flat agricultural plateaus to the north and northwest of Beaufays offer promising potential for solar PV development. These areas provide larger continuous spaces with minimal shading effects from topographical features. The gentle slopes in these directions, particularly those with southern exposures, could maximize solar energy capture throughout the day. The agricultural lands between Beaufays and Liège present opportunities for solar development due to their more moderate relief and existing infrastructure connections. These areas tend to have fewer steep slopes that would complicate installation and maintenance of large-scale solar arrays.Topographical Challenges
The more rugged terrain to the south and east of Beaufays presents significant challenges for large-scale solar development. The steeper valleys and heavily forested hillsides in these directions would require substantial clearing and grading, raising both environmental concerns and installation costs. The numerous small valleys throughout the region can create localized shading effects, particularly during morning and evening when the sun angle is low. This factor necessitates careful site selection to avoid areas where surrounding hills might cast shadows on potential solar installations for substantial portions of the day. Water features, including the network of streams and small rivers crossing the landscape, also introduce constraints for development. These areas often have associated flood plains and riparian zones that would be unsuitable for solar infrastructure and may be protected by environmental regulations. In summary, the varied topography around Beaufays presents both opportunities and challenges for solar PV development, with the more gently rolling agricultural lands to the north and northwest offering the most promising conditions for large-scale installations.Belgium solar PV Stats as a country
