Solar PV Analysis of Rochefort, Belgium
The location at Rochefort, Wallonia, Belgium is a decent spot for generating energy through solar PV, but it's not the most ideal. This is because the amount of electricity you can produce from solar varies throughout the year. During summer and spring, you can expect to generate more energy - about 5.25kWh/day and 4.63kWh/day respectively per kW of installed solar power. However, during autumn and winter, this falls significantly to around 2.46kWh/day and 1.18kWh/day respectively.
This means that if you're planning on using solar power in Rochefort all year round, you'll need to plan for these fluctuations in energy generation - perhaps by using batteries to store excess energy produced in summer or by having a backup source of power for the darker months.
For maximum efficiency at this location with fixed panel installation, your panels should be tilted at an angle of 43 degrees facing South.
In terms of environmental or weather factors that could affect your solar production at this location - Rochefort does experience some cloud cover which could reduce the amount of sunlight reaching your panels especially during autumn and winter months when sunlight hours are already reduced due to shorter days.
Furthermore, snowfall during winter might cover up your panels reducing their effectiveness even further unless cleared regularly.
In terms of local factors that might impede on production - topography doesn't seem particularly relevant here as long as there are no significant obstructions like tall buildings or trees blocking sunshine from reaching your panels directly.
To mitigate these potential challenges:
1) You may want to consider installing a system that allows you to adjust the tilt angle seasonally so as to capture maximum sunlight throughout different times in a year.
2) Regular cleaning/maintenance would also help ensure better performance especially after snowfall or heavy rain.
3) If possible install additional capacity (more panels) so that even with lower efficiency due to weather conditions, you still generate enough power.
Remember, while solar power can be a great way to generate electricity, it's important to consider all these factors before deciding on an installation.
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 Rochefort
Seasonal solar PV output for Latitude: 50.1627, Longitude: 5.2215 (Rochefort, 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 Rochefort, Belgium
To maximize your solar PV system's energy output in Rochefort, Belgium (Lat/Long 50.1627, 5.2215) 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 Rochefort, 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 Rochefort, 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 | 63° South in Winter | 42° 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 Rochefort, 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 Rochefort, 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 Rochefort, Belgium
Rochefort, Belgium is located in the region of Wallonia and is characterized by a hilly landscape with forests, rivers, and valleys. The area is part of the Ardennes mountain range which extends into neighboring Luxembourg and France. The topography includes plateaus, ridges, and low-lying areas.
In terms of solar PV installation, flat or gently sloping areas are generally best suited as they can maximize sun exposure throughout the day. Considering this and the local topography, potential suitable locations could include:
1. Open fields or meadows: These areas often have good sun exposure and minimal shading from trees or buildings.
2. Rooftops: In urbanized parts of Rochefort or nearby towns such as Marche-en-Famenne or Ciney, rooftops can provide ample space for solar panels.
3. Brownfield sites: These are previously developed lands that are not currently in use. If there are any such sites in the vicinity that have been cleared for redevelopment but remain unused due to economic reasons might be worth considering.
However, it's important to note that successful large-scale solar PV installation also depends on other factors such as local climate (amount of sunlight), land availability/ownership issues, proximity to power grids for easy transmission etc., apart from just topographical suitability.
A detailed feasibility study using satellite imagery combined with ground-level surveys would be required to identify exact locations best suited for large-scale solar PV installations in this region.
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.
