The location at Oudenaarde, Flanders, Belgium is somewhat suitable for generating solar energy throughout the year with some variations due to seasonal changes. The amount of electricity that can be produced from a kW of installed solar panels changes with each season.
During summer and spring, the potential output is quite high - 5.4kWh/day in summer and 4.98 kWh/day in spring per kW of installed solar. This means that these seasons are ideal times to generate solar power because there's more sunlight available.
In contrast, autumn and winter have lower outputs - 2.55kWh/day in autumn and only 1.19kWh/day in winter per kW of installed solar. This is because there's less sunlight during these seasons so you can't produce as much electricity from your solar panels.
For a fixed panel installation at this location, tilting the panels at an angle of 43 degrees towards the south would maximize total yearly production from your solar PV system.
As far as environmental or local factors that could affect production, weather conditions like heavy cloud cover or fog could potentially reduce the amount of sunlight reaching your panels thus lowering their output especially during autumn and winter months when sunlight is already limited.
To help ensure greater energy production despite these factors, consider installing a tracking system which allows your panels to follow the sun’s path across the sky thereby increasing their exposure to direct sunlight throughout the day regardless of season or weather condition; also regular cleaning/maintenance will keep them free from dirt or debris that could obstruct light absorption.
Additionally, investing in higher efficiency modules which perform better under low-light conditions might be beneficial considering Belgium's cloudy climate while also ensuring proper design/installation techniques are employed to optimize performance even under such challenging conditions.
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 Oudenaarde
Seasonal solar PV output for Latitude: 50.8498, Longitude: 3.6092 (Oudenaarde, 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 Oudenaarde, Belgium
To maximize your solar PV system's energy output in Oudenaarde, Belgium (Lat/Long 50.8498, 3.6092) 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 Oudenaarde, 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 Oudenaarde, 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 Oudenaarde, 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 Oudenaarde, 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 Oudenaarde, Belgium
Oudenaarde is located in the Flemish region of Belgium and its topography is characterized by a mix of flat plains and gentle hills. The area is part of the Scheldt river valley, which contributes to its relatively flat terrain. However, it also has some hilly areas due to its proximity to the Ardennes mountain range.
In terms of solar PV installation, large-scale projects would ideally require open and flat terrains for maximum exposure to sunlight. Given this requirement, the flatter regions around Oudenaarde could be suitable for such installations. These could include agricultural lands or other open spaces that are not heavily forested or built-up.
However, it's important to note that suitability for solar PV also depends on factors beyond just topography - including local climate conditions (like average hours of sunlight), legal regulations about land use, availability and cost of land among others.
Also worth noting is that modern solar technology can adapt quite well even in less than ideal conditions - like installing panels on slopes facing south (in Northern hemisphere) or using tracking systems that follow sun’s path across sky etc.
Lastly, before any large-scale project can be planned an in-depth feasibility study taking into account all these factors should be conducted with help from experts in field.
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.
