Solar PV Analysis of Overijse, Belgium
Overijse, Flanders, Belgium (50.7688, 4.5383) offers a favorable environment for solar PV power generation throughout the year. The average energy production per kilowatt of installed solar capacity is as follows: 5.25 kWh/day during summer, 2.46 kWh/day in autumn, 1.18 kWh/day in winter and 4.63 kWh/day in spring.
The sun-drenched summer months are particularly conducive to high levels of solar energy generation due to longer daylight hours and elevated temperatures that enhance the efficiency of the panels.
However, seasonal weather variations may impact this efficiency negatively at times - heavy rain or snow can obscure sunlight from reaching the panels thereby reducing their output potential significantly.
To mitigate these effects and ensure consistent energy production year-round, it would be beneficial to install the panels at an optimal angle - specifically a tilt of approximately 43 degrees towards South would be ideal for a fixed panel installation at this location.
This tilt angle will ensure maximum exposure to sunlight across different seasons while also aiding natural cleaning process by allowing rainwater to wash away any accumulated debris on the surface of the panels which could otherwise impede their performance.
It's worth noting that Overijse's geographical location and local topography do not present any significant barriers to solar power generation although regular maintenance checks should still be carried out especially after periods of severe weather conditions such as heavy snowfall or storms - these could potentially damage the equipment or cause misalignment issues affecting overall system performance.
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 Overijse
Seasonal solar PV output for Latitude: 50.7688, Longitude: 4.5383 (Overijse, 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 Overijse, Belgium
To maximize your solar PV system's energy output in Overijse, Belgium (Lat/Long 50.7688, 4.5383) 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 Overijse, 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 Overijse, 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 Overijse, 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 Overijse, 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 Overijse, Belgium
The topography around Overijse, Belgium is mostly flat with some rolling hills. Areas nearby that would be most suitable for large-scale solar PV installations are the open fields and farmland in the surrounding area. These areas provide plenty of space for large solar arrays and have minimal obstructions from trees or buildings that could shade the panels. Additionally, these areas tend to get good amounts of sunlight throughout the year, making them ideal locations for solar energy production.
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.
