Solar PV Analysis of Antwerp, Belgium
Antwerp, Flanders, Belgium (latitude: 51.2192, longitude: 4.3917) is a suitable location for generating solar power through photovoltaic (PV) systems. The average energy production per day for each kilowatt of installed solar capacity varies across seasons: 5.35 kWh in summer, 2.33 kWh in autumn, 1.17 kWh in winter, and 4.56 kWh in spring.
The highest energy generation occurs during the summer months due to increased temperatures and longer daylight hours compared to other seasons. However, certain weather conditions such as cloud cover or rain can impact the efficiency of solar PV systems at this location by reducing sunlight exposure and increasing cooling from precipitation.
Moreover, strong winds may lead to dust accumulation on panels which can decrease their efficiency over time. During winter months, snowfall has the potential to obstruct sunlight entirely for extended periods if not cleared promptly.
To optimize energy production at this location, it is recommended that fixed-panel installations be tilted at an angle of 43 degrees facing southward. This orientation maximizes exposure to sunlight throughout the year without requiring panel tracking systems.
In order to mitigate potential issues related to weather conditions and environmental factors affecting solar power generation in Antwerp:
1) Regular maintenance should be performed on solar panels to remove dust or debris that could reduce their efficiency.
2) Snow removal measures should be implemented during winter months when necessary.
3) Consideration should be given to installing additional protective equipment such as wind barriers or anti-reflective coatings on panels if local conditions warrant it.
By taking these precautions into account during installation and ongoing maintenance processes, Antwerp's suitability for generating solar power year-round can be further enhanced despite any potential challenges posed by its local environment or weather patterns.
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 Antwerp
Seasonal solar PV output for Latitude: 51.2192, Longitude: 4.3917 (Antwerp, 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 Antwerp, Belgium
To maximize your solar PV system's energy output in Antwerp, Belgium (Lat/Long 51.2192, 4.3917) 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 Antwerp, 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 Antwerp, 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 Antwerp, 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 Antwerp, 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 Antwerp, Belgium
The topography around Antwerp, Belgium is mostly flat with some rolling hills. Areas that are most suitable for large-scale solar PV would be those with open spaces and exposure to direct sunlight such as rooftops, agricultural fields, and other available land. Areas that have a south or southwest facing orientation would also be ideal for optimal 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.
