Solar PV Analysis of Hanau, Germany
Hanau, Hesse, Germany is a suitable location for generating solar power throughout the year. The average energy production per kW of installed solar capacity in each season is as follows: 5.25 kWh/day in Summer, 2.34 kWh/day in Autumn, 1.11 kWh/day in Winter, and 4.29 kWh/day in Spring. These values indicate that Hanau experiences higher levels of sunlight during the summer and spring months compared to autumn and winter.
For optimal energy generation from a fixed panel installation at this location (latitude: 50.1367, longitude: 8.9243), it is recommended to tilt the panels at an angle of 42 degrees facing south.
Although there are no significant environmental or topographical factors that would impede solar production in Hanau, Hesse, occasional cloudy days or periods of rain could temporarily reduce the amount of power generated by solar panels due to limited direct sunlight exposure on such days.
To ensure greater energy production despite these weather conditions, it may be beneficial to install high-quality solar panels with better low-light performance and maintain regular cleaning schedules to keep the panels free from dirt or debris that could further obstruct sunlight absorption.
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 Hanau
Seasonal solar PV output for Latitude: 50.1367, Longitude: 8.9243 (Hanau, 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 Hanau, Germany
To maximize your solar PV system's energy output in Hanau, Germany (Lat/Long 50.1367, 8.9243) 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 Hanau, 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 Hanau, 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 Hanau, 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 Hanau, 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 Hanau, Germany
The topography around Hanau, Germany is generally flat. The area is mostly comprised of farmland and low hills. Areas to the south, east and west of Hanau are relatively flat with few obstructions, making them ideal for large-scale solar PV installations. These areas would receive direct sunlight most of the day and have minimal shading from trees or other structures.
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.
