Solar PV Analysis of Harmelen, Netherlands
Harmelen, Utrecht, a town in the Netherlands, presents a mixed picture for solar energy generation throughout the year. Located in the Northern Temperate Zone, this site experiences significant seasonal variations in solar output.
Seasonal Solar Performance
Summer stands out as the most productive season, with solar panels generating an average of 5.42 kWh per day for each kilowatt of installed capacity. Spring follows closely, yielding 4.36 kWh/day. However, the output drops considerably during autumn to 2.14 kWh/day, and reaches its lowest point in winter at just 1.01 kWh/day.
These figures indicate that Harmelen's solar potential is heavily skewed towards the warmer months. The long summer days and higher sun angles contribute to peak performance from late spring through early autumn. Conversely, the short, often overcast winter days significantly limit solar production during the colder months.
Optimal Panel Installation
To maximize year-round energy production, fixed solar panels in Harmelen should be tilted at a 44-degree angle facing south. This optimal angle helps capture the most sunlight throughout the year, balancing the low winter sun with the high summer sun.
Environmental Factors and Mitigation
Several environmental factors can impact solar production in Harmelen:
- Cloud cover: The Netherlands is known for its frequent overcast conditions, particularly in autumn and winter. This can significantly reduce solar output.
- Rain and humidity: High levels of precipitation and humidity can decrease panel efficiency and may require more frequent cleaning.
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 remove dirt and grime that can accumulate due to rain and humidity.
- Consider a dual-axis tracking system for larger installations to maximize light capture throughout the day and year.
While Harmelen's location is not ideal for year-round solar production, proper system design and maintenance can still yield significant energy benefits, especially during the more favorable months.
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 Harmelen
Seasonal solar PV output for Latitude: 52.0927, Longitude: 4.9566 (Harmelen, 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 44° South in Harmelen, Netherlands
To maximize your solar PV system's energy output in Harmelen, Netherlands (Lat/Long 52.0927, 4.9566) throughout the year, you should tilt your panels at an angle of 44° 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 Harmelen, 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 Harmelen, Netherlands. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 44° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 35° South in Summer | 55° South in Autumn | 65° South in Winter | 44° 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 Harmelen, 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 Harmelen, 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 Harmelen, Netherlands
The area around Harmelen, Netherlands, is characterized by a predominantly flat landscape typical of much of the country. This region, located in the western part of the Netherlands, is part of the larger Rhine-Meuse-Scheldt river delta. The topography is marked by low-lying plains with very little variation in elevation.
The land surrounding Harmelen is largely reclaimed from former wetlands and is now primarily used for agriculture. You'll find a patchwork of fields, meadows, and pastures stretching out in all directions. Small streams and drainage canals crisscross the landscape, helping to manage water levels in this low-lying area.
To the north and east of Harmelen, you'll find the Oude Rijn (Old Rhine) river, which meanders through the landscape. This river, once a major branch of the Rhine, is now much smaller but still influences the local geography. The river's banks are slightly elevated compared to the surrounding land, creating subtle variations in the otherwise flat terrain.
Regarding areas suitable for large-scale solar PV (photovoltaic) installations, the flat nature of the landscape around Harmelen offers several potential opportunities. The most suitable locations would likely be found in the open agricultural areas surrounding the town. These areas benefit from minimal shading and obstruction, allowing for maximum sun exposure throughout the day.
Specifically, the fields to the south and southwest of Harmelen might be particularly well-suited for solar PV development. These areas tend to have larger, uninterrupted stretches of land that could accommodate extensive solar arrays. Additionally, being slightly further from the river, these locations may have a lower risk of flooding, which is an important consideration for long-term infrastructure projects in the Netherlands.
However, it's important to note that the use of agricultural land for solar installations is often a subject of debate, balancing the need for renewable energy against the preservation of farmland. Any large-scale solar development would need to carefully consider these factors, as well as local zoning regulations and environmental impact assessments.
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.
