The location at Vilvoorde, Flanders, Belgium is moderately suitable for generating energy via solar photovoltaic (PV) systems year-round. The amount of electricity that can be produced depends on the season, with the highest output occurring in summer and spring.
In simple terms, for every kilowatt of solar power installed at this location, you can expect to generate about 5.25 units of electricity each day during the summer. This decreases to about 4.63 units per day in the spring, drops further to around 2.46 units per day in autumn and falls to its lowest at about 1.18 units per day during winter.
So if you're planning on using solar energy here, it's best to rely more heavily on it during the sunnier months of spring and especially summer when production will be highest.
It's also important how you install your panels - they should ideally be tilted at an angle facing southwards by around 43 degrees as this will help capture maximum sunlight throughout the year.
However there are some factors that might affect how much energy you can produce from a solar PV system in Vilvoorde.
Belgium has a temperate maritime climate with significant rainfall throughout the year which could reduce sunlight exposure for your panels - particularly during wetter seasons or stormy weather periods when cloud cover is heavier.
Winter days are also shorter meaning less sunshine hours for solar production - coupled with potential snowfall which could cover your panels reducing their effectiveness temporarily until cleared off again.
To counteract these issues where possible; consider installing a tracking system so your panels follow the sun across its path through sky maximizing exposure time; ensure regular maintenance checks including clearing any debris like leaves or snow off panel surfaces promptly; consider investing in high-efficiency modules designed better perform under lower light conditions typical of places like Belgium compared standard ones suited better towards sunnier climates instead.
Also remember while local environmental conditions may pose challenges, they are not insurmountable and with proper planning and maintenance, solar PV systems can still be a viable option for sustainable energy production in Vilvoorde.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 201 locations across Belgium. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Vilvoorde
Seasonal solar PV output for Latitude: 50.9251, Longitude: 4.4282 (Vilvoorde, 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 Vilvoorde, Belgium
To maximize your solar PV system's energy output in Vilvoorde, Belgium (Lat/Long 50.9251, 4.4282) 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 Vilvoorde, 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 Vilvoorde, 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 Vilvoorde, 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 Vilvoorde, 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 Vilvoorde, Belgium
Vilvoorde, Belgium is located in the central part of the country and is characterized by a relatively flat topography. The region is part of the Belgian coastal plain which extends inland from the North Sea. It has an average elevation of around 20 meters above sea level.
The areas most suited for large-scale solar PV installations would be open, flat areas with minimal shading and good sun exposure. Considering Vilvoorde's location in a largely urbanized area, it might be difficult to find large tracts of unused land suitable for such developments. However, there are opportunities for rooftop solar installations on commercial or industrial buildings.
Additionally, agricultural lands could also potentially host solar panels without significantly impacting their primary use – this practice is known as agrivoltaics or dual-use farming. Unused lands near transportation infrastructure like highways or railroads may also be potential sites for solar farms.
However, any plan to install large-scale solar PV would need to take into account local planning regulations and environmental considerations such as impact on local wildlife and habitats. Furthermore, Belgium's climate isn't the sunniest so that could affect efficiency and energy production levels of solar panels.
Belgium solar PV Stats as a country
Belgium ranks 19th in the world for cumulative solar PV capacity, with 6,585 total MW's of solar PV installed. This means that 6.60% of Belgium's total energy as a country comes from solar PV (that's 10th in the world). Each year Belgium is generating 569 Watts from solar PV per capita (Belgium ranks 5th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Belgium?
Yes, there are several incentives for businesses wanting to install solar energy in Belgium. The Belgian government offers a range of financial support measures for businesses that invest in renewable energy sources such as solar power. These include tax deductions, grants and subsidies, as well as access to low-interest loans. Additionally, the Flemish Energy Agency (VEA) provides free advice and guidance on how to make the most of these incentives.
