Solar PV Analysis of Herve, Belgium
The location of Herve, Wallonia, Belgium, situated at latitude 50.64 and longitude 5.7888, presents both opportunities and challenges for solar PV energy generation throughout the year. This Northern Temperate Zone location experiences significant seasonal variations in solar energy production.
Seasonal Solar Output
Solar energy generation in Herve follows a predictable pattern aligned with the changing seasons. Summer stands out as the most productive period, with an impressive daily output of 5.25 kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.63 kWh/day. However, the colder months see a substantial decrease in energy production, with autumn yielding 2.46 kWh/day and winter dropping to a mere 1.18 kWh/day.
Optimal Times for Solar Generation
The most favorable period for solar energy production in Herve spans from late spring through early autumn. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. The peak generation typically occurs around the summer solstice in June, gradually tapering off as autumn approaches.
Panel Installation Considerations
To maximize year-round solar energy production in Herve, Wallonia, fixed solar panels should be installed at a tilt angle of 43 degrees facing south. This optimal angle helps balance energy capture across seasons, compensating for the sun's varying positions throughout the year.
Environmental and Weather Factors
Several factors can impact solar energy production in Herve:
- Cloud cover: The region experiences frequent overcast conditions, particularly in autumn and winter, which can significantly reduce solar output.
- Precipitation: Rain and snow, common in the area, can temporarily decrease panel efficiency.
- Short winter days: The limited daylight hours during winter months contribute to reduced energy generation.
Mitigation Strategies
To address these challenges and optimize solar energy production in Herve, Wallonia, consider implementing the following measures:
- Use high-efficiency solar panels designed to perform well in low-light conditions.
- Install a robust cleaning system to remove snow and debris, maintaining panel efficiency.
- Implement micro-inverters or power optimizers to minimize the impact of partial shading on overall system performance.
- Consider a hybrid system combining solar with other renewable energy sources to ensure consistent power supply throughout the year.
By taking these factors into account and implementing appropriate strategies, residents of Herve can make the most of their solar PV installations despite the seasonal variations and environmental challenges.

Solar output per kW of installed solar PV by season in Herve
Seasonal solar PV output for Latitude: 50.64, Longitude: 5.7888 (Herve, 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 Herve, Belgium
To maximize your solar PV system's energy output in Herve, Belgium (Lat/Long 50.64, 5.7888) 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 Herve, 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 Herve, 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 | 53° 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 Herve, 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 Herve, 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 Herve, Belgium
The area around Herve, Belgium, is characterized by a gently rolling landscape typical of the Pays de Herve region. This picturesque countryside features a mix of open pastures, small woodlands, and scattered farmsteads. The terrain is generally undulating, with low hills and shallow valleys creating a patchwork of fields and meadows.
The elevation in this area varies, but it's generally between 200 to 300 meters above sea level. The topography is not particularly steep or mountainous, which makes it suitable for various land uses, including agriculture and potentially solar energy installations.
To the north and west of Herve, the land gradually slopes down towards the Meuse Valley, while to the east and southeast, the terrain becomes slightly more elevated as it approaches the fringes of the Ardennes region. Small streams and brooks crisscross the landscape, contributing to the area's lush, green appearance.
Regarding areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, several factors need to be considered. The ideal locations would be:
- Open, relatively flat areas with minimal shading from trees or buildings. These could include larger agricultural fields or former industrial sites.
- South-facing slopes, which would receive more direct sunlight throughout the day and potentially increase the efficiency of solar panels.
- Areas close to existing electrical infrastructure to facilitate grid connection.
- Locations that are not prime agricultural land or ecologically sensitive areas.
Some potential areas that might meet these criteria could be found in the more open, agricultural landscapes to the north and west of Herve. Additionally, any brownfield sites or former industrial areas in the broader region around Liège might be suitable for solar PV development, as they often provide large, open spaces with existing infrastructure connections.
However, it's important to note that specific site selection for large-scale solar PV would require detailed local studies, including solar irradiance measurements, environmental impact assessments, and consultation with local authorities and communities. The relatively high latitude of Belgium means that careful planning is needed to maximize the effectiveness of solar installations in this region.
