Francofonte, Sicily, Italy, situated at 37.2245° N latitude and 14.874° E longitude, offers a promising location for solar PV energy generation throughout the year. This Mediterranean town experiences varying levels of solar potential across the seasons, with notable peaks and troughs in energy production.

Seasonal Solar Performance

The solar output in Francofonte demonstrates significant seasonal fluctuations. Summer stands out as the most productive period, with an impressive 7.84 kWh per day for each installed kilowatt of solar capacity. Spring follows as the second-most productive season, yielding 6.18 kWh/day. In contrast, autumn and winter see a considerable drop in energy generation, producing 3.76 kWh/day and 3.02 kWh/day, respectively.

Optimal Panel Positioning

To maximize year-round solar energy production in Francofonte, Sicily, fixed solar panels should be tilted at a 32-degree angle facing south. This optimal tilt angle takes into account the town's latitude and the sun's changing position throughout the year, ensuring the best possible exposure to sunlight across all seasons.

Environmental Considerations

While Francofonte's climate is generally favorable for solar energy production, there are a few environmental factors to consider. The region can experience occasional dust storms, particularly during the drier summer months. These events may temporarily reduce panel efficiency by coating them with a layer of fine particles. To mitigate this issue, regular cleaning and maintenance of the solar panels is crucial.

Additionally, the area may face sporadic hailstorms, which could potentially damage solar panels. Installing hail-resistant panels or protective covers can help safeguard the system against such weather events. Lastly, the proximity to Mount Etna, an active volcano, means that ash fall could occur, albeit rarely. In such cases, prompt cleaning of the panels would be necessary to maintain optimal performance.

Conclusion

Despite these minor challenges, Francofonte remains an excellent location for solar PV installations. With its abundant sunshine, particularly during spring and summer, and manageable environmental factors, the town offers a promising opportunity for sustainable energy production throughout the year.

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

Seasonal solar PV output for Latitude: 37.2245, Longitude: 14.874 (Francofonte, Italy), 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 32° South in Francofonte, Italy

To maximize your solar PV system's energy output in Francofonte, Italy (Lat/Long 37.2245, 14.874) throughout the year, you should tilt your panels at an angle of 32° 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 Francofonte, 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 Francofonte, Italy. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
21° South in Summer	41° South in Autumn	52° South in Winter	29° 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 Francofonte, 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 Francofonte, 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 Francofonte, Italy

The area surrounding Francofonte, Italy, located at 37.2245 degrees north latitude and 14.874 degrees east longitude, is characterized by a diverse and picturesque topography typical of the Sicilian landscape. This region, situated in the southeastern part of Sicily, features a mix of gently rolling hills, expansive plains, and occasional steep slopes. Francofonte itself is nestled in the foothills of the Iblei Mountains, a limestone plateau that dominates much of southeastern Sicily. The town is positioned at an elevation of approximately 280 meters above sea level, offering panoramic views of the surrounding countryside. To the north and east of Francofonte, the terrain gradually rises towards the higher peaks of the Iblei range, with some areas reaching elevations of over 500 meters. To the south and west of Francofonte, the landscape transitions into a more open and level plain known as the Piana di Catania. This fertile lowland area stretches towards the Ionian Sea, providing a stark contrast to the hillier regions nearby. The plain is intersected by several rivers and streams, which have carved shallow valleys and created alluvial deposits over time.

Suitability for Large-Scale Solar PV

When considering areas near Francofonte for large-scale solar photovoltaic (PV) installations, the Piana di Catania presents the most promising opportunities. This extensive plain offers several advantages for solar energy development: Firstly, the relatively flat terrain of the Piana di Catania provides ample space for the installation of solar panels without the need for significant land modification. The open nature of the plain also minimizes shading from natural features, allowing for optimal sun exposure throughout the day. Secondly, the area's proximity to the coast ensures a high number of sunny days per year, with Sicily boasting some of the highest solar irradiation levels in Europe. This abundance of sunlight translates to greater potential energy generation for solar PV systems. Additionally, the plain's agricultural heritage means that there are likely to be large, contiguous parcels of land available for development, which is crucial for utility-scale solar projects. The existing road infrastructure in the area would also facilitate the construction and maintenance of solar installations. While the hillier areas around Francofonte may offer some suitable sites for smaller solar projects, their steeper slopes and more varied terrain make them less ideal for large-scale developments. These areas would require more extensive site preparation and could face challenges related to accessibility and grid connection. In conclusion, the diverse topography around Francofonte provides a range of landscapes, from mountainous terrain to expansive plains. For large-scale solar PV projects, the Piana di Catania to the south and west of Francofonte emerges as the most suitable area, offering the space, sunlight, and infrastructure necessary for successful solar energy development.
