Cervignano del Friuli, Italy, located at 45.8189° N latitude and 13.336° E longitude, presents a somewhat challenging environment for year-round solar PV energy generation. This Northern Temperate Zone location experiences significant seasonal variations in solar output, which impacts the overall efficiency of solar installations.

Seasonal Solar Output

The solar energy production at this location varies considerably throughout the year:

• Summer: 7.05 kWh/day per kW installed
• Spring: 5.41 kWh/day per kW installed
• Autumn: 3.22 kWh/day per kW installed
• Winter: 1.66 kWh/day per kW installed

These figures indicate that solar energy generation is most effective during the summer months, with spring also providing good output. However, autumn and especially winter see a significant drop in production.

Optimal Panel Positioning

For fixed panel installations in Cervignano del Friuli, the ideal tilt angle to maximize year-round solar production is 39 degrees facing South. This angle helps to optimize energy capture across all seasons, balancing the high sun angle in summer with the lower sun angle in winter.

Environmental and Weather Factors

While Cervignano del Friuli doesn't face extreme environmental challenges for solar production, there are some factors to consider: 1. Fog and cloud cover: The region can experience foggy conditions, particularly in autumn and winter, which may reduce solar output. 2. Snowfall: Although not frequent, occasional winter snowfall could temporarily cover panels, reducing efficiency.

Preventative Measures

To mitigate these challenges and ensure greater energy production, consider the following measures when installing solar PV systems: 1. Use anti-reflective coatings on panels to improve performance in low-light conditions. 2. Install panels at the optimal 39-degree tilt to help shed snow and maximize year-round production. 3. Implement a regular cleaning schedule, especially during autumn and winter, to remove any debris or snow accumulation. 4. Consider using microinverters or power optimizers to minimize the impact of partial shading on overall system performance.

In conclusion, while Cervignano del Friuli is not ideal for year-round solar energy production due to significant seasonal variations, proper system design and maintenance can still yield satisfactory results, especially during the spring and summer months.

Solar output per kW of installed solar PV by season in Cervignano Del Friuli

Seasonal solar PV output for Latitude: 45.8189, Longitude: 13.336 (Cervignano Del Friuli, 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 39° South in Cervignano Del Friuli, Italy

To maximize your solar PV system's energy output in Cervignano Del Friuli, Italy (Lat/Long 45.8189, 13.336) throughout the year, you should tilt your panels at an angle of 39° 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 Cervignano Del Friuli, 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 Cervignano Del Friuli, Italy. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
29° South in Summer	49° South in Autumn	60° South in Winter	38° 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 Cervignano Del Friuli, 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 Cervignano Del Friuli, 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 Cervignano Del Friuli, Italy

The area surrounding Cervignano del Friuli in northeastern Italy is characterized by a diverse and gently transitioning topography. This region, situated in the Friuli-Venezia Giulia autonomous region, features a mix of flat lowlands and gradually rising terrain as one moves away from the coast. To the south and southeast of Cervignano del Friuli, the landscape is predominantly flat, forming part of the expansive Friulian Plain. This area is marked by rich agricultural lands, crisscrossed by numerous rivers and irrigation channels. The terrain here is very low-lying, with elevations barely above sea level in many places. As one moves northward and slightly westward from Cervignano del Friuli, the topography begins to change. The land starts to rise gradually, transitioning into gently rolling hills. These hills become more pronounced as you continue north, eventually giving way to the foothills of the Julian Alps and the Carnic Alps further in the distance. To the east, the landscape maintains its relatively flat character for some distance before encountering the limestone plateau of the Karst region. This unique geological area is known for its rugged, rocky terrain and numerous caves.

Suitability for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, the flat expanses of the Friulian Plain to the south and southeast of Cervignano del Friuli present the most promising opportunities. These areas offer several advantages for solar PV development: Firstly, the flat terrain reduces the costs and complexity associated with site preparation and construction. It also minimizes shading issues between solar panels, allowing for optimal arrangement and spacing of the arrays. Secondly, these lowland areas typically receive ample sunlight throughout the year, with fewer obstructions from hills or mountains that could cast shadows or reduce solar exposure. Additionally, the agricultural nature of much of this land means that there are often large, open spaces available that could potentially be repurposed or dual-purposed for solar energy production. However, it's important to note that the use of productive agricultural land for solar installations can be controversial and may face regulatory hurdles. Therefore, the most suitable locations would likely be on marginal agricultural lands or areas already zoned for industrial use within this flat region. The gently rolling hills to the north might also offer some potential for solar PV, particularly on south-facing slopes. However, these areas would generally be less ideal than the flatter regions due to increased construction complexity and potential shading issues.
