Solar PV Analysis of Worms, Germany
The city of Worms, located in Rheinland-Pfalz, Germany is in a decent position for generating energy through solar panels throughout the year. However, some seasons are better than others.
During summer and spring, the solar panels can generate a good amount of electricity. Specifically, you can expect around 5.55 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar in summer and 4.57 kWh/day per kW in spring. This means that these are the best times to generate solar power at this location.
However, during autumn and winter months the output drops significantly due to less sunlight hours and lower sun angle. In autumn it drops to 2.59 kWh/day per kW and even further down to just 1.24 kWh/day per kW during winter.
To make sure you're getting as much energy as possible from your solar panels all year round at this location, it's recommended that they be installed at an angle facing 42 degrees South for maximum sun exposure.
Now let's talk about potential obstacles that could reduce your overall energy production from these panels in Worms:
Firstly, environmental factors such as cloudy weather or heavy snowfall during winter might decrease the efficiency of your solar panel system because they block sunlight from reaching the panels.
Secondly, local topography could also play a role if there are hills or tall buildings casting shadows on your installation site during certain parts of the day or year.
Lastly other factors like dust deposition on panel surface may also affect its performance over time by blocking sunlight absorption.
To counteract these issues:
- You can install a snow guard or use heating elements so heavy snow doesn't accumulate on your panels.
- Regular cleaning will help remove dust which might have settled on them.
- If shadows are an issue due to nearby structures or natural features like hills/trees etc., you might want to consider installing your panels on a higher structure or pole to avoid this.
In conclusion, while Worms isn't the most ideal location for year-round solar energy production due to its seasonal variations in sunlight, with proper installation and maintenance you can still generate a substantial amount of power.
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 Worms
Seasonal solar PV output for Latitude: 49.6603, Longitude: 8.3438 (Worms, 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 42° South in Worms, Germany
To maximize your solar PV system's energy output in Worms, Germany (Lat/Long 49.6603, 8.3438) throughout the year, you should tilt your panels at an angle of 42° 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 Worms, 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 Worms, Germany. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 42° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 33° South in Summer | 52° 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 Worms, 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 Worms, 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 Worms, Germany
Worms, Germany is located in the Rhine Valley with relatively flat terrain. The city is situated on the west bank of the Rhine River and is surrounded by a mix of agricultural land, vineyards, and forests.
For large-scale solar PV installations, areas with flat or gently sloping terrains are most suitable as they require less groundwork and are easier for installation. Therefore, the agricultural lands around Worms could potentially be suitable for such installations. However, this would need to be balanced against any potential impact on farming activities.
In addition to topography, factors like local climate (amount of sunlight), land use regulations, proximity to power grids (for ease of connecting the generated power), and potential environmental impacts should also be considered when identifying suitable sites for large-scale solar PV projects.
It's also worth noting that Germany has been a global leader in solar energy production so there may already be established infrastructure and regulatory frameworks in place that could facilitate such projects.
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.
