Solar PV Analysis of Kortenberg, Belgium
The location at Kortenberg, Flanders, Belgium, is somewhat suitable for generating energy via solar PV panels year-round. However, the amount of energy that can be generated varies significantly with each season.
In summer and spring, when there is more sunlight available due to longer daylight hours and clearer skies, the panels can generate quite a bit of power - around 5.25kWh/day in summer and 4.63kWh/day in spring per kW of installed solar.
However, in autumn and winter when the days are shorter and there are potentially more clouds covering the sun, these figures drop to 2.46kWh/day in autumn and just 1.18kWh/day in winter per kW of installed solar.
To get the most out of your solar installation year-round at this location it's recommended to tilt your panels at an angle facing 43 degrees South as this will help capture more sunlight over the course of a day throughout all seasons.
There could be some local factors that might affect how much energy you can generate from your PV system here though such as buildings or trees blocking sunlight from reaching your panels or harsh weather conditions like snowfall which could cover up your panels making them less effective until cleared off again.
One way to mitigate against these potential issues would be by ensuring that you install your system somewhere where it won't be blocked by other structures or large trees if possible. Also consider setting up a maintenance plan for keeping them clean especially during months where snowfall may occur often so they continue working efficiently throughout those colder months too.
In summary: while not ideal due to varying seasonal changes affecting sunlight availability; with careful planning regarding installation location/angle plus regular maintenance/cleaning - you should still be able to produce a decent amount of power using solar PV here across all four seasons overall despite these challenges.
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 Kortenberg
Seasonal solar PV output for Latitude: 50.8837, Longitude: 4.549 (Kortenberg, 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 Kortenberg, Belgium
To maximize your solar PV system's energy output in Kortenberg, Belgium (Lat/Long 50.8837, 4.549) 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 Kortenberg, 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 Kortenberg, 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 Kortenberg, 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 Kortenberg, 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 Kortenberg, Belgium
Kortenberg, Belgium is located in the Flemish Region of Belgium, known for its relatively flat terrain. The topography is characterized by gentle slopes and plains with occasional small hills. The area has a mix of urban and rural landscapes including farmlands, forests, and residential areas.
Large-scale solar PV installations require large tracts of land that have good sun exposure. In the context of Kortenberg's topography, the following areas may be suitable:
1) Farmlands: Large farms could potentially host ground-mounted solar panels if they have sufficient unused or less productive land.
2) Industrial Areas: Industrial zones or warehouses with large rooftops can be ideal for rooftop solar installations.
3) Brownfield Sites: Unused or abandoned industrial lands (brownfield sites) are often suitable for large-scale solar projects due to their size and lack of competing uses.
4) Infrastructure-adjacent Lands: Land near highways or railway lines can also be considered as these areas are often underutilized.
However, it should be noted that feasibility for large scale PV will not only depend on topography but also on other factors such as local climate (solar irradiation), grid connectivity possibilities, environmental impact assessments, local regulations regarding land use and renewable energy projects etc. Detailed site-specific studies would need to be conducted to identify most suited locations.
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.
