Heerlen, Limburg, Netherlands, situated at latitude 50.8756 and longitude 5.9718, presents a mixed picture for solar energy generation throughout the year. Located in the Northern Temperate Zone, this city experiences significant seasonal variations in solar output.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Heerlen, Limburg, with an average daily output of 5.25 kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.63 kWh/day. These seasons offer the best conditions for solar energy production, with longer days and higher sun angles.
Autumn sees a considerable drop in solar output, producing 2.46 kWh/day. Winter presents the greatest challenge, with a meager 1.18 kWh/day, due to shorter days, lower sun angles, and typically overcast conditions.
Optimizing Solar Panel Installation
To maximize year-round solar energy production in Heerlen, Limburg, fixed solar panels should be tilted at a 43-degree angle facing south. This optimal angle takes into account the city's latitude and seasonal sun positions, ensuring the best overall performance throughout the year.
Environmental and Weather Considerations
Heerlen's climate poses some challenges for solar energy production. The region experiences frequent cloud cover, especially during autumn and winter months, which can significantly reduce solar panel efficiency. Additionally, the area is prone to occasional hail storms, which could potentially damage solar panels.
To mitigate these issues, consider the following preventative measures:
- Install hail-resistant solar panels or protective covers to safeguard against potential storm damage.
- Implement a regular cleaning schedule to remove dust and debris, which can accumulate more readily in humid conditions.
Despite these challenges, with proper installation and maintenance, solar energy remains a viable option for Heerlen, Limburg, particularly during the spring and summer months when production potential is at its highest.
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 364 locations across Netherlands. 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 Heerlen
Seasonal solar PV output for Latitude: 50.8756, Longitude: 5.9718 (Heerlen, Netherlands), 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 Heerlen, Netherlands
To maximize your solar PV system's energy output in Heerlen, Netherlands (Lat/Long 50.8756, 5.9718) 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 Heerlen, Netherlands
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 Heerlen, Netherlands. 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 Heerlen, Netherlands
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 Heerlen, Netherlands.
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 Heerlen, Netherlands
The area around Heerlen, Netherlands, is characterized by a gently rolling landscape typical of the southern Limburg region. This part of the Netherlands is known for its unique topography compared to the rest of the country, which is predominantly flat. The terrain around Heerlen features low hills and shallow valleys, creating a picturesque and varied landscape.
The elevation in and around Heerlen ranges from about 100 to 200 meters above sea level. This undulating terrain is part of the larger South Limburg hill country, which extends into neighboring Belgium and Germany. The area is crisscrossed by small streams and rivers, contributing to the formation of subtle valleys between the hills.
Despite the hilly nature of the region, there are still areas that could be suitable for large-scale solar PV installations. The most promising locations for solar farms would likely be found on the broader, flatter hilltops or in the more expansive valley floors. These areas would offer the advantage of relatively level ground, which is preferable for the installation and maintenance of solar panels.
Ideal sites for solar PV projects would be open fields or former agricultural lands that are not heavily forested or urbanized. Areas to the north and east of Heerlen, where the landscape begins to flatten out towards the Meuse River valley, might offer more extensive tracts of suitable land. These locations would potentially provide the space needed for large-scale solar installations while minimizing the need for significant land alterations.
It's important to note that while the topography around Heerlen is favorable in many areas, other factors such as local zoning regulations, proximity to electrical infrastructure, and environmental considerations would also play crucial roles in determining the most suitable locations for large-scale solar PV projects. Any potential development would need to balance these factors with the topographical advantages of the chosen site.
Netherlands solar PV Stats as a country
Netherlands ranks 12th in the world for cumulative solar PV capacity, with 14,249 total MW's of solar PV installed. This means that 8.90% of Netherlands's total energy as a country comes from solar PV (that's 7th in the world). Each year Netherlands is generating 817 Watts from solar PV per capita (Netherlands ranks 1st in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Netherlands?
Yes, there are several incentives for businesses wanting to install solar energy in the Netherlands. The Dutch government offers a number of financial incentives and subsidies for businesses that invest in renewable energy sources such as solar power. These include grants, tax credits, and low-interest loans. Additionally, businesses can benefit from net metering policies which allow them to sell excess electricity back to the grid at a premium rate. Finally, businesses may also be eligible for additional funding through the European Union's Horizon 2020 program.
