Francavilla Fontana, Apulia, Italy, located at 40.5249° N, 17.5823° E, presents a mixed picture for solar PV energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar energy production.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 7.69 kWh per day for each kW of installed solar capacity. Spring follows as the second-best season, generating 5.93 kWh/day. However, autumn and winter see a substantial drop in production, with 3.60 kWh/day and 2.45 kWh/day respectively.

These figures indicate that Francavilla Fontana is particularly well-suited for solar energy generation during the warmer months, from late spring through early autumn. The long, sunny days of summer provide ideal conditions for maximizing solar output.

Optimal Panel Installation

To maximize year-round solar production at this location, fixed solar panels should be installed at a tilt angle of 34 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun positions across seasons.

Environmental Considerations

While Francavilla Fontana generally offers favorable conditions for solar energy production, there are some environmental factors to consider:

1. Dust and pollen: The region's agricultural activities may lead to increased dust and pollen in the air, potentially reducing panel efficiency.
2. Coastal proximity: The town's relative closeness to the coast might expose panels to salt air, which can cause corrosion over time.

To mitigate these issues, regular cleaning of the panels is recommended. Additionally, using corrosion-resistant materials and protective coatings can help safeguard the solar installation against salt air damage.

In conclusion, while Francavilla Fontana experiences significant seasonal variations in solar energy production, its location still offers good potential for solar PV installations, especially during the warmer months. With proper installation techniques and maintenance, solar energy can be a viable and efficient power source in this Italian town.

Ideally tilt fixed solar panels 34° South in Francavilla Fontana, Italy

To maximize your solar PV system's energy output in Francavilla Fontana, Italy (Lat/Long 40.5249, 17.5823) throughout the year, you should tilt your panels at an angle of 34° 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 Francavilla Fontana, Italy

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 Francavilla Fontana, Italy. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
24° South in Summer	44° South in Autumn	55° South in Winter	33° 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 Francavilla Fontana, Italy

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 Francavilla Fontana, Italy.

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 Francavilla Fontana, Italy

The area surrounding Francavilla Fontana in southern Italy is characterized by gently rolling hills and expansive plains typical of the Puglia region. This picturesque landscape is dotted with olive groves, vineyards, and scattered farmhouses, creating a patchwork of agricultural land that stretches for miles in every direction. The terrain is generally flat to mildly undulating, with occasional shallow valleys and low ridges breaking up the otherwise level topography. To the east of Francavilla Fontana, the land gradually slopes towards the Adriatic Sea, about 20 kilometers away. This coastal plain becomes increasingly flat as it approaches the shoreline. To the west, the terrain becomes slightly more varied, with some modest hills rising from the countryside. However, even these elevations are relatively gentle, rarely exceeding 200 meters above sea level.

Potential for Solar PV Installation

The topographical features of the region surrounding Francavilla Fontana make it well-suited for large-scale solar photovoltaic (PV) installations. The abundance of flat or gently sloping land provides ideal conditions for solar farms, as it minimizes the need for extensive land preparation and allows for optimal panel placement to capture sunlight. Areas to the east and southeast of Francavilla Fontana, where the terrain flattens out towards the coast, would be particularly suitable for solar PV projects. These expansive plains offer large, uninterrupted spaces that could accommodate extensive arrays of solar panels. The lack of significant natural obstacles or steep gradients in these areas would simplify construction and maintenance processes. Additionally, the agricultural nature of the region presents opportunities for dual-use solar installations, where solar panels can be integrated with existing farmland. This approach, known as agrivoltaics, could be particularly effective in the vast olive groves and vineyards that characterize the landscape, allowing for both energy production and continued agricultural activities. It's worth noting that while the entire region receives ample sunlight due to its southern location, areas further from the coast might be slightly preferable for solar PV installations. This is because coastal zones can sometimes experience increased humidity and salt spray, which could potentially impact the efficiency and longevity of solar panels. Therefore, the gently rolling hills to the west and northwest of Francavilla Fontana could also be excellent locations for solar farms, combining favorable topography with slightly more inland conditions. In conclusion, the topography around Francavilla Fontana offers numerous opportunities for large-scale solar PV development. The combination of flat plains, gentle slopes, and abundant sunlight makes this region an attractive prospect for renewable energy projects, with the potential to significantly contribute to Italy's green energy goals.
