Solar PV Analysis of Metz, France
The location in Metz, Grand Est, France is decent for generating energy through solar photovoltaic (PV) panels year-round, but it's not the most ideal. The amount of electricity that can be produced from each kilowatt of installed solar panels varies throughout the year. In summer and spring, you can expect to generate more electricity (5.33kWh/day and 4.63kWh/day respectively), while in autumn and winter, the output drops significantly (2.60kWh/day and 1.22kWh/day respectively). This means that if you're planning on using solar power as your main source of energy at this location, you'll need to have a plan for storing excess energy during sunnier seasons or having an alternative source during less sunny ones.
To get the most out of your solar PV system throughout the year at this location, it's best to tilt your panels at an angle of 42 degrees facing South. This will maximize their exposure to sunlight over all four seasons.
As with any location, there are some environmental factors that might hinder solar production in Metz such as cloudy weather or heavy snowfall which could block sunlight from reaching the panels especially during autumn and winter months when sunshine hours are already reduced due to shorter days.
To ensure greater energy production despite these challenges:
1) Regular maintenance: Keep your panels clean so they can absorb as much light as possible - dust and debris can reduce efficiency.
2) Snow removal: If snow accumulates on the panel surface it should be removed carefully without damaging them; however remember safety first – if they’re mounted high up or difficult access then professional help may be needed.
3) Consider installing a tracking system: These systems allow your panels to follow the sun’s path across sky which increases their exposure time particularly useful in lower light conditions like autumn/winter months.
4) Energy storage solutions: Consider investing in battery storage system so you can store excess energy produced during summer/spring for use in autumn/winter.
Remember, while Metz may not be the most ideal location for solar energy production, with proper planning and preparation, it's still possible to harness a significant amount of power from the sun.
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 Metz
Seasonal solar PV output for Latitude: 49.1198, Longitude: 6.1522 (Metz, 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 42° South in Metz, France
To maximize your solar PV system's energy output in Metz, France (Lat/Long 49.1198, 6.1522) 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 Metz, 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 Metz, France. 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 | 62° South in Winter | 41° 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 Metz, 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 Metz, 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 Metz, France
Metz, France is located in the northeastern part of the country. The topography of this region is characterized by a mix of flat plains and gently rolling hills. There are also several rivers flowing through the area including Moselle River.
The region around Metz receives a moderate amount of sunlight throughout the year, making it suitable for solar PV installations. However, given that large-scale solar PV requires significant land space and optimal sun exposure, certain areas would be more suited than others.
1. Flat Plains: The flat plains surrounding Metz could potentially be ideal for large-scale solar PV installations as they provide vast open spaces with direct sunlight exposure.
2. Farmlands: With proper planning and design, farmlands can host dual-purpose solar farms that allow agriculture and energy production to coexist.
3. Industrial Zones: Areas designated for industrial use may have available land or rooftops suitable for installing large scale solar panels.
4. Brownfields/Unused Land: Any unused lands or brownfield sites (areas previously used for industrial purposes) can be repurposed into renewable energy sites without disturbing natural habitats or agricultural activities.
However, any decision on where to place these installations should take into account various factors such as local zoning regulations, potential environmental impacts, grid connectivity infrastructure and community acceptance towards such projects.
It's always recommended to carry out detailed site assessments including sun irradiance studies before deciding on specific locations for large-scale Solar PV projects.
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.
