Solar PV Analysis of Massy, France
The location at Massy, France is somewhat suitable for generating energy via solar photovoltaic (PV) systems year-round. However, the amount of electricity that can be generated varies significantly depending on the season.
In summer and spring, you can expect to generate a good amount of electricity - 5.56 kilowatt-hours per day in summer and 4.97 kilowatt-hours per day in spring for every kilowatt of solar panels installed. This makes these seasons ideal times to generate solar power at this location.
However, during autumn and winter, the output drops quite a bit due to shorter daylight hours and less intense sunlight - down to 2.89 kWh/day in autumn and just 1.34 kWh/day in winter per kW of installed solar.
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 southwards as it will maximise total year-round production from your setup.
Local factors that could affect solar production include weather conditions such as cloud cover or fog which reduce sunlight exposure on the panels; also snowfall during winter months could cover up your panels reducing their efficiency drastically until cleared off.
Preventative measures that can be taken when installing solar systems include setting up automatic or manual panel cleaning mechanisms that help clear off snow or dust from time-to-time ensuring greater energy production throughout the year irrespective of weather conditions; also consider using tracking mounts which adjust panel positions according to sun’s path during different seasons thereby maximizing their exposure towards direct sunlight all through the year.
Remember though while considering investing into Solar Panels: The higher initial costs should be offset by long-term savings from producing free renewable energy over many years ahead!
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 Massy
Seasonal solar PV output for Latitude: 48.7283, Longitude: 2.2815 (Massy, 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 Massy, France
To maximize your solar PV system's energy output in Massy, France (Lat/Long 48.7283, 2.2815) 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 Massy, 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 Massy, 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 |
|---|---|---|---|
| 32° 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 Massy, 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 Massy, 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 Massy, France
Massy, France is located in the Île-de-France region, which is mostly flat with gentle rolling hills. The topography does not have significant elevation changes or mountainous terrain that could potentially obstruct sunlight.
The most suitable areas for large-scale solar PV installations would be open and flat spaces that receive a lot of sunlight throughout the year. These could include agricultural lands, rooftops of large buildings, or unused industrial sites.
However, it's important to note that while topography and sun exposure are key factors in determining suitability for solar PV installations, other factors such as land use regulations, proximity to electrical grids for power transmission, and local climate conditions (like average cloud cover) also play a crucial role.
In terms of specific nearby locations with potential for large scale solar PV installations - Saclay plateau to the west of Massy could be considered due to its relatively flat terrain and abundance of open space. Additionally areas like Parc de Vilgénis or along highways A10/A6 where there are wide-open spaces might also be suitable.
But any decision about installing solar panels should involve careful site-specific analysis including environmental impact assessments.
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.
