Bressuire, France, situated at latitude 46.8446 and longitude -0.4965, presents a mixed landscape for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.

Seasonal Solar Performance

The solar energy potential in Bressuire fluctuates considerably across the seasons. Summer stands out as the most productive period, with an impressive daily output of 6.18 kWh per kW of installed solar capacity. Spring follows closely behind, generating 5.69 kWh/day. However, the performance drops noticeably in autumn, with 3.24 kWh/day, and plummets to a mere 1.57 kWh/day during the winter months.

These figures highlight that the most ideal times for solar energy generation in Bressuire are from late spring through early autumn. During this period, longer days and higher sun angles contribute to increased solar radiation, resulting in peak energy production.

Optimal Panel Installation

To maximize year-round solar energy production in Bressuire, fixed solar panels should be installed at a tilt angle of 40 degrees facing south. This angle has been calculated to optimize the capture of solar radiation throughout the year, taking into account the location's latitude and seasonal sun path variations.

Environmental Considerations

While Bressuire's climate is generally favorable for solar energy production, there are some factors that could potentially impact system performance:

1. Cloud cover: The region experiences cloudy conditions, particularly during autumn and winter, which can reduce solar irradiance.
2. Precipitation: Rainfall and occasional snow can temporarily decrease panel efficiency.

To mitigate these challenges, consider implementing the following measures:

• Use high-efficiency solar panels that perform well in low-light conditions
• Install a robust cleaning system to remove dirt and snow accumulation
• Implement micro-inverters or power optimizers to minimize the impact of partial shading

By addressing these factors, solar installations in Bressuire can achieve better year-round performance, capitalizing on the strong summer and spring production while minimizing losses during the less favorable seasons.

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 Bressuire

Seasonal solar PV output for Latitude: 46.8446, Longitude: -0.4965 (Bressuire, 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 40° South in Bressuire, France

To maximize your solar PV system's energy output in Bressuire, France (Lat/Long 46.8446, -0.4965) throughout the year, you should tilt your panels at an angle of 40° 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 Bressuire, 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 Bressuire, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° 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	50° South in Autumn	61° South in Winter	39° 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 Bressuire, 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 Bressuire, France.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Bressuire, France

The landscape surrounding Bressuire, a commune in western France, is characterized by gently rolling hills and expansive rural areas. This region, known as the Bocage Bressuirais, features a patchwork of fields, meadows, and small woodlands, creating a picturesque countryside typical of the Deux-Sèvres department. The topography around Bressuire is relatively mild, with elevations ranging from approximately 100 to 200 meters above sea level. The terrain is predominantly composed of low, undulating hills interspersed with shallow valleys. These gentle slopes are the result of centuries of erosion, shaping the landscape into its current form. Numerous small streams and rivers crisscross the area, contributing to the formation of minor valleys and creating a diverse ecosystem. The Argenton River, a tributary of the Thouet, flows near Bressuire, further enhancing the region's topographical variety.

Potential for Large-Scale Solar PV

When considering areas suitable for large-scale solar photovoltaic (PV) installations near Bressuire, several factors come into play. The most promising locations would be those that combine favorable topography with minimal environmental and agricultural impact. South-facing slopes in the vicinity of Bressuire could be particularly well-suited for solar PV projects. These areas receive more direct sunlight throughout the day, maximizing energy production potential. The gentle nature of the hills in this region means that many slopes are not too steep for solar panel installation, which is advantageous for construction and maintenance. Large, open fields that are currently underutilized or have poor agricultural yield might be prime candidates for solar farms. These areas often provide the necessary space for extensive arrays of solar panels without significantly disrupting valuable farmland or natural habitats. It's worth noting that the region's rural character means that there are likely to be fewer obstacles to solar energy production, such as tall buildings or industrial complexes that could cast shadows on solar panels. However, care should be taken to avoid areas of ecological importance or historical significance, which are common in this part of France. Proximity to existing electrical infrastructure should also be considered when identifying suitable locations for large-scale solar PV installations. Areas near power lines or substations could reduce the cost and complexity of connecting new solar farms to the grid. In conclusion, while the rolling landscape around Bressuire presents some challenges for large-scale solar PV development, there are certainly areas that could be well-suited for such projects. The key lies in carefully balancing the need for renewable energy with the preservation of the region's agricultural heritage and natural beauty.

France solar PV Stats as a country
