Solar PV Analysis of Grimma, Germany
Grimma, Saxony, Germany is a fairly decent location for generating solar energy year-round. However, it's not the most ideal due to its position in the Northern Temperate Zone and the varying amounts of sunlight received throughout different seasons.
In simple terms, during summer you can expect your solar panels to produce around 5.16 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of installed solar power. This is because there are more daylight hours and stronger sunlight intensity during this season.
Autumn sees a drop in production to about 2.20 kWh/day per kW due to shorter days and less intense sunlight as we move away from the summer months. Winter has even less output at only around 0.99 kWh/day per kW because it has the shortest days with weaker sunlight intensity.
However, spring shows improvement again with an average output of about 4.12 kWh/day per kW as daylight hours start increasing and we get closer to summer conditions again.
To maximize total year-round production from your solar panels at this location, they should be installed at an angle facing roughly 43 degrees towards the south since that direction gets maximum sun exposure throughout all seasons in Grimma.
As far as environmental or weather factors go that could potentially hinder solar production here; cloud cover during different times of year could possibly reduce productivity by blocking direct sunlight on some days but this would not have a significant impact overall if your system is designed properly.
Potential preventative measures include installing tracking systems that follow the sun’s path across the sky for better exposure or using advanced modules capable of producing power even under cloudy conditions which can further boost efficiency rates despite such local climatic challenges.
Lastly also consider regular maintenance like cleaning off any snowfall or debris build-up on your panels which could otherwise block incoming light and reduce energy generation capacity over time.
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 Grimma
Seasonal solar PV output for Latitude: 51.2317, Longitude: 12.7233 (Grimma, 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 43° South in Grimma, Germany
To maximize your solar PV system's energy output in Grimma, Germany (Lat/Long 51.2317, 12.7233) throughout the year, you should tilt your panels at an angle of 43° 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 Grimma, 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 Grimma, Germany. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 43° 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 | 43° 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 Grimma, 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 Grimma, 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 Grimma, Germany
Grimma, Germany is located in the Free State of Saxony and is surrounded by a mixed topography. The area features rolling hills, forests, and open fields with some flatlands. It is crossed by the Mulde River.
The ideal locations for large-scale solar PV installations would be areas that have relatively flat terrain and are not heavily shaded or obstructed by natural formations such as trees or hills. Open fields around Grimma could be suitable for this purpose as they receive ample sunlight throughout the year.
However, it's important to note that while geographical suitability is crucial, there are other factors to consider when determining the feasibility of a solar farm project such as local climate conditions (amount of sunshine), land availability and use restrictions, proximity to power grids for transmission purposes, etc. Therefore a detailed site-specific assessment would be necessary before making any decisions.
Also keep in mind that Germany has specific regulations about renewable energy projects which may also influence where you can place these 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.
