Solar PV Analysis of Ixelles-Elsene, Belgium
Ixelles-Elsene, Brussels Capital, Belgium, situated at latitude 50.8344 and longitude 4.368, presents a mixed picture for solar PV energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which impacts the overall efficiency of solar installations.
Seasonal Solar Performance
The solar energy production in Ixelles-Elsene varies considerably across seasons. Summer stands out as the most productive period, with an average daily output of 5.25 kWh per kW of installed solar capacity. Spring follows closely, generating 4.63 kWh/day. However, there's a sharp decline in autumn, with only 2.46 kWh/day, and winter sees the lowest production at a mere 1.18 kWh/day.
These figures highlight that the location is most ideal for solar energy generation from late spring through early autumn. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency.
Optimizing Solar Panel Installation
To maximize year-round solar energy production in Ixelles-Elsene, Brussels Capital, fixed solar panels should be installed at a tilt angle of 43 degrees facing south. This optimal angle helps capture the most sunlight throughout the year, balancing the lower winter sun with the higher summer sun.
Environmental and Weather Factors
Several factors can impede solar production in this location:
- Cloud cover: Belgium's climate is known for frequent cloudy days, especially in autumn and winter, which can significantly reduce solar output.
- Rain and snow: Precipitation can temporarily decrease panel efficiency, with snow potentially covering panels in winter.
To mitigate these issues, consider the following preventative measures:
- Install high-efficiency panels that perform better in low-light conditions
- Use micro-inverters or power optimizers to minimize the impact of partial shading
- Implement a tilted installation to help snow slide off panels
- Regular cleaning and maintenance to ensure optimal performance
While Ixelles-Elsene may not be ideal for year-round solar production due to its northern latitude and weather patterns, proper installation and maintenance can still make solar PV a viable renewable energy option, especially during the more productive 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 Ixelles-Elsene
Seasonal solar PV output for Latitude: 50.8344, Longitude: 4.368 (Ixelles-Elsene, 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 Ixelles-Elsene, Belgium
To maximize your solar PV system's energy output in Ixelles-Elsene, Belgium (Lat/Long 50.8344, 4.368) 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 Ixelles-Elsene, 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 Ixelles-Elsene, 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 Ixelles-Elsene, 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 Ixelles-Elsene, 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 Ixelles-Elsene, Belgium
Ixelles-Elsene is a municipality located in the Brussels-Capital Region of Belgium. The topography of the area around Ixelles-Elsene is generally characterized by gentle slopes and low-lying terrain. The region is part of the broader Brussels Basin, which is a relatively flat area with some subtle variations in elevation.
The landscape in and around Ixelles-Elsene features a mix of urban development and green spaces. The terrain gradually rises from the lower-lying areas in the north and west towards the southeast. This gentle incline is most noticeable in the southern part of Ixelles-Elsene, where you can find slightly higher elevations.
One of the most prominent topographical features in the area is the Ixelles Ponds, a series of small lakes that were formed in a natural valley. These ponds are situated in a slight depression, surrounded by gently sloping banks. The surrounding streets and neighborhoods follow the contours of this depression, creating a subtle bowl-like shape in the local topography.
Regarding areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, it's important to note that the Brussels-Capital Region is highly urbanized, which limits the available space for such projects. However, some potential areas to consider might include:
1. Industrial zones on the outskirts of Brussels, particularly to the south and west of Ixelles-Elsene, where there might be large roof spaces or unused land parcels.
2. Former agricultural lands in the more rural areas surrounding Brussels, especially towards the south and southeast, where the terrain is slightly more elevated and open.
3. Repurposed brownfield sites or abandoned industrial areas within the broader Brussels region, which could offer large, flat surfaces ideal for solar installations.
4. Large public buildings or institutions with extensive roof space, such as universities, hospitals, or government complexes in and around Ixelles-Elsene.
It's worth noting that while the topography around Ixelles-Elsene is generally favorable for solar PV due to its relatively flat nature, the high density of urban development and limited open spaces pose challenges for large-scale installations. Any significant solar projects in this area would likely need to focus on integrating PV systems into existing structures or utilizing innovative approaches to maximize limited available space.
