The location at Mulhouse, Grand Est, France is fairly good for generating energy via solar photovoltaic (PV) systems year-round. The amount of electricity that can be generated from each kilowatt of installed solar changes with the seasons. During the summer months, you can expect to generate about 5.74 kWh/day per kW of installed solar power, which is quite high due to longer daylight hours and more direct sunlight. In spring and autumn, the output drops slightly to 4.89 kWh/day and 3.02 kWh/day respectively as days become shorter and the sun's position in the sky changes.
However, during winter months when days are shortest and there's less sunlight due to cloud cover or foggy conditions common in this region, you can only expect about 1.45 kWh/day per kW of installed solar power - significantly lower than other seasons but still a source of energy generation.
To get the most out of your solar PV system in Mulhouse throughout the year, it would be ideal to tilt your panels at an angle facing towards south by approximately 41 degrees - this helps maximize exposure to sunlight over different times of day across all seasons.
While Mulhouse has generally favourable conditions for solar energy production, there could be some local factors that might affect its efficiency such as heavy snowfall during winter which could block sunlight from reaching your panels or accumulation on them reducing their effectiveness; also occasional foggy conditions might reduce visibility thereby affecting light penetration.
To mitigate these potential issues:
1) It's advisable that snow guards be installed above panels preventing accumulation on them.
2) Regular maintenance checks should also ensure they're clean & clear for maximum light absorption.
3) If possible consider installing automated tracking systems which adjust panel angles throughout day maximizing exposure even under less optimal weather conditions like fog etc.
4) Also consider investing in high-quality PV modules known for better performance under low-light situations.
Remember while these measures may increase initial setup costs, they could significantly improve your system's overall efficiency and payback period.
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 627 locations across France. 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 Mulhouse
Seasonal solar PV output for Latitude: 47.7452, Longitude: 7.3379 (Mulhouse, France), 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 41° South in Mulhouse, France
To maximize your solar PV system's energy output in Mulhouse, France (Lat/Long 47.7452, 7.3379) throughout the year, you should tilt your panels at an angle of 41° 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 Mulhouse, France
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 Mulhouse, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 41° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 31° South in Summer | 51° South in Autumn | 61° South in Winter | 40° 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 Mulhouse, France
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 Mulhouse, France.
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 Mulhouse, France
Mulhouse is located in the eastern part of France, near the borders with Germany and Switzerland. The topography around Mulhouse is diverse, with a mix of flat plains and hilly areas. The city itself lies on the plain between the Vosges mountains to the west and the Rhine River to the east.
To determine which areas would be most suited for large-scale solar PV installations, several factors need to be taken into account such as:
1) Sunlight: Solar panels require direct sunlight for maximum efficiency.
2) Land Availability: Large-scale solar PV projects require substantial land area that isn't shaded or obstructed.
3) Proximity to Grid Infrastructure: Locations close to existing power grid infrastructure are preferable since it reduces costs related to transporting electricity.
Considering these factors, flat open spaces with good sun exposure would be ideal for large scale solar PV installations. In this context, areas on the plains towards east of Mulhouse closer to Rhine river may offer suitable locations given their relatively flat terrain and openness. Also potentially suitable could be cleared or low-value agricultural lands where such an installation wouldn't interfere significantly with local ecology or productivity.
However, any decision should also take into account local regulations about land use and renewable energy projects as well as potential social impacts (like visual impact). A thorough feasibility study including site inspection should precede any decisions about specific locations for large-scale solar PV installations.
France solar PV Stats as a country
France ranks 11th in the world for cumulative solar PV capacity, with 14,718 total MW's of solar PV installed. This means that 2.80% of France's total energy as a country comes from solar PV (that's 30th in the world). Each year France is generating 218 Watts from solar PV per capita (France ranks 23rd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in France?
Yes, there are several incentives for businesses wanting to install solar energy in France. The French government offers a range of financial incentives and tax credits to encourage businesses to invest in renewable energy sources such as solar power. These include the Feed-in Tariff (FiT), which pays businesses for the electricity they generate from their solar panels, and the Investment Tax Credit (ITC), which provides a 30% tax credit on investments made in renewable energy systems. Additionally, businesses may be eligible for grants or loans from local authorities or regional development agencies.
