Temse, Flanders, Belgium, located in the Northern Temperate Zone at coordinates 51.122°N, 4.2144°E, presents a moderate solar energy generation potential that varies significantly throughout the year.
Seasonal Solar Performance
The solar energy output at this location shows typical Northern European patterns, with substantial seasonal variation. Summer provides the strongest performance at 5.29 kWh per day per kW of installed capacity, making it the peak season for solar generation. Spring follows as the second-best period with 4.49 kWh per day per kW, offering nearly comparable performance to summer months. Autumn production drops considerably to 2.26 kWh per day per kW, while winter presents the most challenging conditions with only 1.11 kWh per day per kW. This dramatic seasonal swing means that summer produces nearly five times more energy than winter, which is characteristic of higher latitude locations.Optimal Installation Configuration
For fixed panel installations at this location, the ideal tilt angle is 43 degrees facing south to maximize total year-round production. This angle is calculated by analyzing daily solar elevation angles throughout the year and weighting them according to solar irradiance potential, accounting for Earth's elliptical orbit.Local Factors Affecting Solar Production
Several environmental and weather factors in Temse could significantly impact solar energy generation:- Maritime climate influence: Belgium's coastal proximity creates frequent cloud cover and overcast conditions, particularly during autumn and winter months
- High humidity and fog: The location near the Scheldt River can generate morning fog and persistent moisture that reduces solar irradiance
- Frequent precipitation: Belgium experiences regular rainfall throughout the year, creating cloudy conditions that diminish solar output
- Industrial air quality: The Antwerp industrial region nearby may contribute to atmospheric particles that can accumulate on panels and reduce efficiency
Preventative Measures for Optimal Performance
To maximize solar energy production despite these challenges, several installation strategies should be considered:- Regular cleaning systems: Install automated cleaning mechanisms or schedule frequent manual cleaning to remove dust, pollen, and industrial residue that accumulates more readily in this humid environment
- Enhanced ventilation design: Ensure adequate air circulation behind panels to prevent moisture buildup and maintain optimal operating temperatures
- Quality mounting systems: Use corrosion-resistant materials designed for high-humidity coastal environments to ensure long-term structural integrity
- Micro-inverter technology: Consider individual panel optimization systems to minimize the impact when some panels are shaded by passing clouds or fog
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Temse
Seasonal solar PV output for Latitude: 51.122, Longitude: 4.2144 (Temse, 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 Temse, Belgium
To maximize your solar PV system's energy output in Temse, Belgium (Lat/Long 51.122, 4.2144) 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 Temse, 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 Temse, 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 Temse, 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 Temse, 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 Temse, Belgium
Topography Around Temse, Belgium
The landscape surrounding Temse in East Flanders presents a predominantly flat to gently rolling terrain characteristic of the Flemish lowlands. This region sits within the Scheldt River valley system, creating a naturally low-lying environment with elevations rarely exceeding 50 meters above sea level. The area features the typical polder landscape of northern Belgium, with extensive flat agricultural fields interspersed with small settlements and drainage canals.
The Scheldt River meanders through this region, creating fertile alluvial plains that have been shaped by centuries of agricultural use. The topography consists mainly of open farmland with minimal natural elevation changes, making it part of the broader North European Plain. Small ridges and gentle slopes occasionally break up the otherwise uniform landscape, but these variations are subtle and create only minor undulations across the terrain.
Urban development in the area tends to follow the river systems and historical trade routes, with Temse itself positioned strategically along the Scheldt. The surrounding countryside maintains its agricultural character, dominated by crop fields, pastures, and small woodlands. The flat nature of this region means that natural obstacles to development are minimal, though the presence of waterways, roads, and existing settlements creates a patchwork of available land.
Optimal Areas for Large-Scale Solar PV Development
The extensive agricultural plains south and southwest of Temse present excellent opportunities for large-scale solar installations. These areas offer vast expanses of relatively flat terrain with minimal shading from natural features. The gentle topography eliminates the need for significant site preparation or grading, reducing installation costs and complexity. Fields in this direction also benefit from optimal southern exposure without significant obstructions.
The agricultural zones extending eastward toward Dendermonde also show strong potential for solar development. This region features large, consolidated farm parcels that could accommodate substantial solar arrays while maintaining good access to existing electrical infrastructure. The flat terrain and open aspect ensure consistent solar exposure throughout the day without interference from topographical features.
Areas northwest of Temse, while also topographically suitable, may face more constraints due to higher population density and existing industrial development along the Scheldt corridor. However, brownfield sites and industrial zones in this direction could still offer opportunities for solar development, particularly on large industrial rooftops or remediated industrial land.
The region's proximity to major transportation networks and electrical grid infrastructure enhances the viability of large-scale solar projects. The flat topography minimizes drainage issues and allows for efficient panel layout designs that maximize energy capture. Agricultural areas that are less intensively farmed or those transitioning away from traditional crops could be particularly well-suited for agrivoltaic projects that combine solar generation with continued agricultural use.
