Solar PV Analysis of Wetteren, Belgium
Wetteren, Flanders, Belgium is a fairly good location for generating solar energy throughout the year, but it's not perfect. The amount of electricity that can be produced from solar panels varies depending on the time of year. During the summer and spring, when days are longer and there's more sunlight, you can expect to generate quite a bit of power - around 5.56 kWh per day in the summer and 4.91 kWh per day in spring for each kW installed.
However, during autumn and winter when days are shorter with less sunlight available, your solar panels will produce less electricity - about 2.30 kWh per day in autumn and only about 1.04 kWh per day in winter for each kW installed.
The best times to generate solar energy at this location would therefore be during spring and summer months when there's plenty of sunlight.
If you're installing fixed panel installations here, it's ideal to tilt them at an angle of 43 degrees facing South so they can catch as much sun as possible all year round.
There may be some local factors that could affect how much power your solar panels produce though. For example:
- Weather: Belgium has a temperate maritime climate which means it often has cloudy or overcast skies which could reduce the amount of sunlight reaching your panels.
- Environmental Factors: Any nearby buildings or trees that cast shadows over your panels will also reduce their efficiency.
To get around these issues:
- You might want to consider installing tracking systems which allow your panels to follow the sun across the sky maximizing their exposure.
- Also ensure that where you place your panels isn't overshadowed by any obstructions like buildings or trees especially during peak hours (between 9 am – 3 pm).
Overall though Wetteren is quite suitable for setting up a photovoltaic system just keep these considerations in mind while planning out installation details!
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 Wetteren
Seasonal solar PV output for Latitude: 51.0086, Longitude: 3.883 (Wetteren, 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 Wetteren, Belgium
To maximize your solar PV system's energy output in Wetteren, Belgium (Lat/Long 51.0086, 3.883) 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 Wetteren, 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 Wetteren, 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 |
|---|---|---|---|
| 35° 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 Wetteren, 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 Wetteren, 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 Wetteren, Belgium
Wetteren, Belgium is located in the Flemish region of the country. The topography of this area is generally flat to gently rolling, characteristic of much of Northern Belgium. It lies within the Scheldt river basin and has a mix of urban areas, farmland and forests.
For large-scale solar PV installations, open and relatively flat areas are most suitable as they allow for easier installation and maintenance, as well as more efficient collection of sunlight. In Wetteren's case, unused farmlands or industrial zones could be potential locations for such an installation. However, specific site selection would require more detailed analysis including aspects like land availability and ownership, local planning regulations among others.
It's important to note that while Belgium doesn't have high levels of sunshine comparable to countries closer to the equator; it still has a growing solar energy sector due its commitment towards renewable energy sources. The efficiency improvements in modern solar panels also make them viable even in less sunny climates.
Lastly while selecting sites for large scale Solar PV projects factors such as proximity to grid connection points (to minimize transmission losses) and environmental impact assessments should also be considered.
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.
