Solar PV Analysis of Moirans, France
The location at Moirans, France is somewhat ideal for generating solar energy year-round. The amount of electricity that can be produced from solar panels varies throughout the seasons due to changes in sunlight exposure.
In summer, you can expect to generate about 6.24 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of solar panels installed. This is the most productive season for solar energy generation because there are more hours of daylight and the sun is usually out longer.
During autumn, production drops a bit to around 3.17 kWh/day per kW installed due to shorter days and less intense sunlight as compared to summer.
Winter sees the lowest productivity with about 1.68 kWh/day per kW installed, mainly because of shorter days and often cloudier weather which reduces the amount of sunlight hitting your panels.
Spring sees an increase again with around 5.37 kWh/day per kW installed as days start getting longer again and there's more sunshine.
If you're installing fixed panel installations at this location, tilting them at an angle of 39 degrees facing South would maximize your total year-round production from these solar panels.
As far as local factors that could impede solar production in Moirans go, it's important to consider things like shading from buildings or trees which could block sunlight reaching your panels especially during winter when the sun is lower in the sky; also heavy snowfall or ice accumulation on your panels would reduce their efficiency so regular cleaning might be necessary during winter months.
To prevent these issues affecting your energy production significantly, ensure that any large obstacles casting shadows over where you plan on installing your system are removed if possible before installation; also consider setting up a maintenance schedule for cleaning off any snow or ice buildup during winter months - this will help ensure maximum productivity from your system all year round.
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 Moirans
Seasonal solar PV output for Latitude: 45.3203, Longitude: 5.5547 (Moirans, 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 39° South in Moirans, France
To maximize your solar PV system's energy output in Moirans, France (Lat/Long 45.3203, 5.5547) throughout the year, you should tilt your panels at an angle of 39° 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 Moirans, 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 Moirans, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 29° South in Summer | 49° South in Autumn | 59° South in Winter | 38° 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 Moirans, 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 Moirans, 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 Moirans, France
Moirans, France is situated in the region of Auvergne-Rhône-Alpes. The topography around the area is mostly flat with some gently rolling hills. It is part of the Isère department which lies in a valley between mountain ranges: Chartreuse Mountains to the north and Vercors Massif to the south.
The Rhone River flows near Moirans providing fertile land for agriculture. There are also forests in certain parts, especially towards the mountains.
In terms of suitability for large-scale solar PV installations, areas with flat or gently sloping land that receive good sunlight exposure would be ideal. Given this criteria, agricultural fields or open spaces around Moirans could potentially be suitable for such developments.
However, it's important to note that any solar project should take into account various factors including local regulations and policies, environmental impact assessments and grid connectivity among others.
Moreover, while southern France generally receives more sunlight than northern regions making it more attractive for solar power generation; local microclimatic conditions can significantly influence solar irradiance levels and thus potential energy yield from PV systems. Therefore site-specific assessment would be necessary to determine most suitable 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.
