Solar PV Analysis of Mainz, Germany
The location at Mainz, Rheinland-Pfalz, Germany is fairly good for generating energy via solar panels year-round. The amount of electricity you can expect to generate from each kilowatt (kW) of solar panels installed varies by season. In the summer, you can expect about 5.55 kilowatt-hours (kWh) per day for each kW of solar panel installed. This drops to 2.59 kWh/day in the autumn and 1.24 kWh/day in winter before rising again to 4.57 kWh/day in spring.
This means that the best time of year for generating solar energy at this location is during the summer and spring when sunlight levels are highest. However, even during autumn and winter, some energy generation is still possible.
For a fixed panel installation at this location, tilting your panels at an angle of 42 degrees towards the south will maximize your total yearly production from solar photovoltaic (PV), which turns sunlight directly into electricity.
There may be certain local factors that could affect how much energy you're able to generate with your solar panels in Mainz, Rheinland-Pfalz though these would need further investigation specific to the site's surroundings such as tall buildings or trees that might cast shadows on your panels; weather patterns like frequent cloud cover or fog; or high levels of dust or pollution that could settle on your panels' surfaces and reduce their efficiency.
To counteract these potential issues:
- Regular cleaning: Keeping your panels clean will help ensure they're working as efficiently as possible.
- Proper placement: If there are tall structures nearby that could cast shadows on your panels throughout parts of the day/year it would be ideal if placement options were explored so shadow impact would be minimized.
- Weather protection: Solar PV systems are generally designed to withstand normal weather conditions but if extreme weather events like hailstorms are common in this area then additional protective measures could be considered.
In conclusion, while there are some seasonal and potential environmental factors to consider, Mainz is a solid location for solar energy production.
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 Mainz
Seasonal solar PV output for Latitude: 49.9879, Longitude: 8.297 (Mainz, 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 Mainz, Germany
To maximize your solar PV system's energy output in Mainz, Germany (Lat/Long 49.9879, 8.297) 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 Mainz, 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 Mainz, 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 Mainz, 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 Mainz, 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 Mainz, Germany
Mainz, Germany is located in the Rhineland-Palatinate region and is situated on the western (left) bank of the Rhine river. The topography around Mainz consists of a mix of flat plains along the river and low-lying hills further away from it.
The area is known for its vineyards, particularly those on south-facing slopes which are exposed to plenty of sunlight - these could potentially be suitable for solar PV installations. However, this would need to be balanced against preserving agricultural land use and potential landscape impact.
In terms of urban areas, large buildings with flat rooftops such as warehouses or factories could also provide space for solar panels. In addition, Mainz has numerous open spaces like parks that might be suitable as well.
However, it's important to note that assessing suitability for large-scale solar PV involves many factors including not just topography but also local climate (amount and intensity of sunlight), land availability and use restrictions, environmental impacts, grid connectivity etc. Therefore a comprehensive feasibility study would need to be conducted before any specific sites could be identified as most suited for large scale solar PV installations.
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.
