Agen, France, situated at 44.2001° N latitude and 0.6216° E longitude, presents a moderate opportunity 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

Solar energy production in Agen peaks during the summer months, with an average daily output of 6.22 kWh per kW of installed capacity. Spring follows closely behind, generating 5.38 kWh/day. However, there's a notable decline in autumn, with 3.17 kWh/day, and a significant drop in winter, producing only 1.77 kWh/day.

The substantial difference between summer and winter production highlights the importance of proper system sizing to meet year-round energy needs. While summer offers excellent generation potential, winter months may require supplementary energy sources or increased storage capacity to maintain consistent power supply.

Optimal Panel Installation

For fixed-panel installations in Agen, the ideal tilt angle to maximize year-round solar production is 38 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun positions across seasons.

Environmental and Weather Considerations

Agen's climate presents a few challenges for solar energy production:

• Cloud cover: The region experiences cloudy days, particularly in autumn and winter, which can reduce solar output.
• Fog: Morning fog, common in the Garonne Valley where Agen is located, may delay peak production hours.

To mitigate these factors, consider the following preventative measures:

• Use high-efficiency panels that perform well in low-light conditions
• Implement a robust cleaning schedule to prevent dust and pollen accumulation
• Install micro-inverters or power optimizers to minimize the impact of partial shading

While Agen may not be an ideal location for year-round solar production compared to sunnier regions, it still offers substantial potential, especially during spring and summer. With proper system design and maintenance, solar PV can be a valuable component of the local energy mix, contributing significantly to renewable energy goals.

Solar output per kW of installed solar PV by season in Agen

Seasonal solar PV output for Latitude: 44.2001, Longitude: 0.6216 (Agen, 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 38° South in Agen, France

To maximize your solar PV system's energy output in Agen, France (Lat/Long 44.2001, 0.6216) throughout the year, you should tilt your panels at an angle of 38° 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 Agen, 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 Agen, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
28° South in Summer	48° South in Autumn	59° South in Winter	37° 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 Agen, 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 Agen, 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 Agen, France

The topography around Agen, France, is characterized by a diverse landscape that combines gentle hills, fertile plains, and river valleys. Located in the southwestern part of the country, Agen sits along the banks of the Garonne River, which has played a significant role in shaping the surrounding terrain over millennia. To the north and east of Agen, the land gradually rises into rolling hills and plateaus. These areas are part of the larger Aquitaine Basin, featuring a mix of agricultural fields, orchards, and patches of woodland. The hills are generally modest in elevation, rarely exceeding 200 meters above sea level, creating a picturesque countryside dotted with small villages and farms. South of Agen, the landscape flattens out into the expansive Garonne Valley. This wide, fertile plain is renowned for its agricultural productivity, with vast stretches of farmland dedicated to various crops, including the famous Agen prunes. The valley floor is relatively flat, making it ideal for agriculture and infrastructure development. To the west, the terrain becomes more varied, with a series of low ridges and valleys running roughly parallel to the Garonne River. These features create a patchwork of microclimates and soil types, contributing to the region's diverse agricultural output.

Suitability for Large-Scale Solar PV

When considering areas nearby Agen for large-scale solar photovoltaic (PV) installations, several factors come into play. The most suitable locations would typically be: The Garonne Valley: The expansive, flat areas of the valley floor south of Agen offer excellent potential for solar PV farms. These locations benefit from minimal shading, good sun exposure, and easy access for construction and maintenance. However, care must be taken to balance solar development with the preservation of prime agricultural land. Elevated Plateaus: Some of the higher, flatter areas on the plateaus north and east of Agen could be well-suited for solar installations. These locations often have good sun exposure and may be less valuable for agriculture, making them attractive for renewable energy development. Gently Sloping Hillsides: South-facing slopes in the hilly areas surrounding Agen could be ideal for solar PV, as they naturally maximize exposure to sunlight throughout the day. These locations might be particularly suitable if they are currently underutilized or not prime agricultural land. It's important to note that while the topography around Agen offers several promising areas for solar PV development, any large-scale projects would need to carefully consider environmental impacts, land use regulations, and the region's strong agricultural heritage. Balancing renewable energy goals with the preservation of the area's natural beauty and economic traditions would be crucial for successful implementation.
