Solar PV Analysis of Asse, Belgium
Based on the data provided, Asse, Flanders, Belgium can generate a decent amount of energy via solar PV year-round. However, the amount of electricity produced varies greatly depending on the season.
During summer and spring, with longer daylight hours and more direct sunlight, solar panels in this location can generate quite a lot of power - 5.25kWh/day per kW installed in Summer and 4.63kWh/day per kW installed in Spring.
In contrast, during autumn and winter when days are shorter with less sunshine due to cloud cover or foggy conditions common in these seasons; energy production drops significantly to 2.46kWh/day per kW installed for Autumn and just 1.18kWh/day per kW installed for Winter.
So while you could produce some electricity all year round from solar PV at this location; it would be most effective during spring and summer months.
For fixed panel installations at this location, tilting them at an angle of 43 degrees South is ideal to maximise total year-round production from solar PV.
The weather is a major factor that could impede solar production at this location especially during autumn/winter months due to reduced sunlight caused by overcast skies or foggy conditions common in these seasons. Additionally environmental factors like dust or bird droppings can reduce efficiency by blocking light from reaching the cells within the panels.
To ensure greater energy production despite these challenges:
- Regular cleaning/maintenance of panels will help keep them free from dust/bird droppings.
- Using advanced technology like tracking systems which allow your solar panels to move with sun throughout day ensuring maximum exposure.
- Installing additional capacity (more panels) might also be considered as way to compensate for lower productivity during darker months.
However such decisions should take into account cost-effectiveness based on your specific needs/usage patterns as well as local regulations/support schemes available for renewable energy installations.
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 Asse
Seasonal solar PV output for Latitude: 50.9066, Longitude: 4.1987 (Asse, 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 Asse, Belgium
To maximize your solar PV system's energy output in Asse, Belgium (Lat/Long 50.9066, 4.1987) 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 Asse, 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 Asse, 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 Asse, 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 Asse, 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 Asse, Belgium
Asse, Belgium is located in the Flemish Brabant province of Belgium. The topography of this region is generally flat to gently rolling with a few hilly areas. It's characterized by farmland, forests, and urban areas.
For large-scale solar PV installations, you would typically want an area that gets plenty of sunlight throughout the year and has ample open space for installation. Flat or gently sloping terrain is also ideal as it makes installation easier and more cost-effective.
In the case of Asse, surrounding agricultural lands could be suitable for solar PV if they are not highly productive or necessary for local food production. However, this must be carefully assessed to avoid competition between food production and energy generation.
Another potential location could be rooftops in urban areas within or close to Asse town itself - particularly on large buildings such as warehouses or factories which often have extensive roof surface area that can be utilized for solar panels.
Moreover, brownfield sites (abandoned industrial land) can also serve as good locations for installing large-scale solar projects due to their lower environmental impact compared with greenfield sites (undeveloped land).
However, before any decisions are made about where to install a large scale solar project there should be detailed feasibility studies considering factors like sunlight exposure throughout the year (solar irradiance), grid connection possibilities, environmental impacts etc.
Keep in mind that local regulations and community acceptance will play a crucial role in deciding whether these places could actually host a large scale photovoltaic plant.
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.
