Solar PV Analysis of Hamm, Germany
The location in Hamm, Germany is decent for generating solar energy year-round, but it's not the best. The amount of energy you can get from a solar panel depends on how much sunlight it gets. In Hamm, the amount of sunlight varies quite a bit throughout the year.
In summer, each kilowatt (kW) of installed solar can generate about 5.22 kilowatt-hours (kWh) per day. This is pretty good and would be an ideal time to generate solar power at this location.
In autumn, each kW of installed solar generates about 2.31 kWh per day which is less than half compared to summer.
Winter is the least ideal time with only 1.14 kWh per day generated from each kW of installed solar due to shorter days and less intense sunlight.
Spring sees an improvement with around 4.34 kWh/day generated for each kW of installed solar as days start getting longer and sunnier again.
To maximize total year-round production from your panels at this location, you should tilt them at an angle of 44 degrees facing South if they are fixed installations i.e., not moving or adjustable ones.
As for local factors that could affect your panels' performance in Hamm - like anywhere else - weather conditions such as heavy snowfall or hail could damage your panels or block sunlight reaching them. Buildings or trees might also cast shadows on your panels reducing their productivity if they are nearby and tall enough to do so.
To prevent these issues:
- Install durable panels that can withstand harsh weather.
- Regularly clean snow off your panels in winter.
- Make sure there aren't any obstructions like buildings or trees blocking sunlight when choosing where to install them.
Remember though: Even though some seasons are better than others for generating solar power in Hamm; it's still worth having because over the course of a year it adds up nicely!
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 919 locations across Germany. 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 Hamm
Seasonal solar PV output for Latitude: 51.6452, Longitude: 7.7351 (Hamm, Germany), 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 Hamm, Germany
To maximize your solar PV system's energy output in Hamm, Germany (Lat/Long 51.6452, 7.7351) 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 Hamm, Germany
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 Hamm, Germany. 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 | 54° 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 Hamm, Germany
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 Hamm, Germany.
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 Hamm, Germany
Hamm, Germany is located in the North Rhine-Westphalia region and features mostly flat to slightly hilly terrain. The city is surrounded by agricultural land and forests, with the River Lippe flowing through it.
For large-scale solar PV installations, flat or gently sloping areas are typically most suitable as they provide maximum exposure to sunlight and require less structural support for panel installation. Therefore, the vast agricultural lands around Hamm would be ideal for this purpose.
However, other factors such as local climate conditions (amount of annual sunshine), land use regulations, proximity to electrical grids etc., should also be considered when planning a large-scale solar PV project.
It's worth noting that North Rhine-Westphalia has been one of Germany's leading regions in terms of renewable energy production including solar power. So there may already be established systems or guidelines in place for such projects which could facilitate their implementation.
Germany solar PV Stats as a country
Germany ranks 4th in the world for cumulative solar PV capacity, with 58,461 total MW's of solar PV installed. This means that 9.70% of Germany's total energy as a country comes from solar PV (that's 3rd in the world). Each year Germany is generating 702 Watts from solar PV per capita (Germany ranks 3rd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Germany?
Yes, there are a few incentives for businesses wanting to install solar energy in Germany. These include feed-in tariffs, which guarantee businesses a price per kilowatt hour of electricity produced from their solar system; tax incentives such as the reduction of corporate income taxes; and subsidies from regional governments or utilities. Additionally, Germany's Renewable Energy Sources Act (EEG) provides additional support for projects that involve renewable energies.
