The location in Evere, Brussels Capital, Belgium (50.8729° N, 4.4038° E) presents varying conditions for solar PV energy generation throughout the year. Situated in the Northern Temperate Zone, this area experiences distinct seasonal changes that significantly impact solar energy production.

Seasonal Solar Output

Solar energy generation at this location fluctuates considerably across seasons. Summer proves to be the most productive period, with an average daily output of 5.25 kWh per kW of installed solar capacity. Spring follows closely, yielding 4.63 kWh/day. Autumn sees a notable decrease to 2.46 kWh/day, while winter experiences the lowest output at 1.18 kWh/day.

The substantial difference between summer and winter production highlights the challenges of relying solely on solar energy in this region year-round. However, the relatively high output during spring and summer months makes these seasons ideal for maximizing solar energy generation.

Optimal Panel Installation

To maximize year-round solar energy production at this location, fixed solar panels should be tilted at a 43-degree angle facing south. This optimal angle accounts for the location's latitude and seasonal variations in sun position, ensuring the best possible energy capture throughout the year.

Environmental Factors and Mitigation

Several environmental factors in Evere can impact solar energy production:

1. Cloud cover: Belgium's climate is known for frequent overcast conditions, particularly in autumn and winter. This can significantly reduce solar panel efficiency.
2. Rainfall: The region experiences considerable rainfall, which can temporarily decrease panel output and necessitate more frequent cleaning.
3. Short winter days: The location's northern latitude results in fewer daylight hours during winter months, limiting solar energy production.

To mitigate these challenges, consider the following measures:

• Use high-efficiency panels designed to perform well in low-light conditions
• Implement a regular cleaning schedule to maintain optimal panel performance
• Consider incorporating energy storage solutions to balance seasonal variations in production
• Explore the use of dual-axis tracking systems to maximize energy capture, especially during shorter winter days

While Evere's location presents some challenges for year-round solar energy production, proper system design and maintenance can still yield significant benefits, particularly during the more favorable spring and summer months.

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 Evere

Seasonal solar PV output for Latitude: 50.8729, Longitude: 4.4038 (Evere, 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 Evere, Belgium

To maximize your solar PV system's energy output in Evere, Belgium (Lat/Long 50.8729, 4.4038) 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 Evere, 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 Evere, 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 Evere, 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 Evere, Belgium.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Evere, Belgium

Evere, a municipality in the Brussels-Capital Region of Belgium, is situated in a relatively flat area with subtle topographical variations. The terrain around Evere is characterized by gentle slopes and low-lying plains, typical of the broader Brussels region. The elevation gradually increases from west to east, with the western part of Evere being slightly lower than its eastern counterpart. The landscape surrounding Evere is primarily urban and suburban, with a mix of residential areas, parks, and some remaining agricultural land. To the north and east of Evere, the topography becomes slightly more undulating, with small hills and valleys creating a gently rolling landscape. However, these elevation changes are modest, rarely exceeding a few dozen meters in difference.

Nearby Areas Suitable for Large-Scale Solar PV

When considering areas near Evere for large-scale solar photovoltaic (PV) installations, several factors come into play. The relatively flat terrain in and around Evere is generally favorable for solar PV projects, as it minimizes shading issues and simplifies installation processes. The areas to the east and northeast of Evere, extending towards the municipalities of Zaventem and Machelen, offer potential for large-scale solar PV development. These regions have more open spaces and less dense urban development, providing larger contiguous areas for solar panel arrays. The gentle slopes in these directions can also be advantageous, as they can be oriented to maximize sun exposure throughout the day. Another promising area for solar PV installations lies to the northwest of Evere, in the direction of Vilvoorde. This region features a mix of industrial zones and open spaces that could be repurposed for renewable energy production. The relatively flat terrain in this area would facilitate the installation of large solar arrays with minimal site preparation. It's important to note that while these areas show potential for solar PV development, any large-scale project would need to consider various factors beyond topography. These include local zoning regulations, environmental impact assessments, grid connection capabilities, and the interests of local communities. Additionally, the high population density and urbanization of the Brussels region may limit the availability of extensive open areas for very large solar farms, making it more likely that multiple smaller to medium-sized installations would be more feasible in the vicinity of Evere.
