Azzano Decimo, Friuli Venezia Giulia, Italy presents a moderately favorable location for year-round solar photovoltaic energy generation, though with significant seasonal variations that potential solar installers should carefully consider.

Seasonal Solar Performance

The location experiences substantial differences in solar energy production throughout the year. Summer delivers the strongest performance at 7.07 kWh per day per kW of installed capacity, making it the prime season for solar generation. Spring follows as the second-best period with 5.41 kWh per day per kW, offering excellent production levels that make it nearly as valuable as summer months. Autumn shows a notable decline to 3.22 kWh per day per kW, representing less than half of summer's output. Winter presents the most challenging conditions with only 1.66 kWh per day per kW, producing roughly one-quarter of summer levels.

Optimal Installation Configuration

For maximum year-round energy production at Azzano Decimo, Friuli Venezia Giulia, solar panels should be installed at a fixed tilt angle of 39 degrees facing south. This angle has been calculated to optimize total annual output by accounting for the sun's varying position throughout the year and the location's specific latitude.

Local Environmental Factors

Several environmental and weather factors in the Azzano Decimo region can potentially impact solar energy production:

• Fog and humidity: The Po Valley region, where Azzano Decimo is located, experiences frequent morning fog, particularly during autumn and winter months
• Air pollution: Industrial activity in northern Italy can create atmospheric haze that reduces solar irradiance
• Dust and agricultural particles: The surrounding agricultural areas can contribute to dust accumulation on solar panels
• Snow coverage: Winter weather may occasionally bring snow that can temporarily block solar panels

Preventative Measures for Enhanced Performance

To maximize solar energy production despite these challenges, several installation strategies prove beneficial: Regular cleaning schedules become essential, particularly during harvest seasons when agricultural dust is prevalent. Installing panels with adequate spacing allows for better air circulation and easier maintenance access. Choosing panel mounting systems that facilitate snow shedding helps minimize winter production losses. Anti-soiling coatings on panel surfaces can reduce dust accumulation and make cleaning more effective. Proper drainage around panel installations prevents water pooling that could lead to increased humidity and potential electrical issues. Monitoring systems prove valuable for identifying performance drops that indicate cleaning needs or other maintenance requirements. Given the significant seasonal variation in output, battery storage systems or grid-tie arrangements help balance the substantial difference between summer abundance and winter scarcity.

Solar output per kW of installed solar PV by season in Azzano Decimo

Seasonal solar PV output for Latitude: 45.9143, Longitude: 12.6666 (Azzano Decimo, 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 Azzano Decimo, Italy

To maximize your solar PV system's energy output in Azzano Decimo, Italy (Lat/Long 45.9143, 12.6666) 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 Azzano Decimo, 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 Azzano Decimo, 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	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 Azzano Decimo, 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 Azzano Decimo, 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 Azzano Decimo, Italy

Topographical Features of the Azzano Decimo Region

Azzano Decimo sits within the Friuli-Venezia Giulia region of northeastern Italy, positioned in the heart of the Po Valley's eastern extension. This area is characterized by remarkably flat terrain, forming part of the expansive Pianura Padana that stretches across northern Italy. The landscape around Azzano Decimo consists primarily of fertile alluvial plains that were formed over millennia by sediment deposits from rivers flowing down from the Alps to the north.

The topography exhibits minimal elevation changes, with the terrain gently sloping southward from the foothills of the Alps toward the Adriatic Sea. Agricultural fields dominate the visual landscape, interspersed with small towns, industrial areas, and transportation corridors. The region's flatness is interrupted only by occasional slight undulations and the presence of river channels, including tributaries of the Tagliamento River system.

To the north of Azzano Decimo, the land gradually rises toward the Alpine foothills, while the southern areas remain consistently level as they approach the coastal plains near the Adriatic. The drainage patterns follow natural depressions in the landscape, with water flowing generally from northeast to southwest through a network of rivers, canals, and irrigation channels that serve the area's extensive agricultural operations.

Optimal Areas for Large-Scale Solar Development

The flat topography surrounding Azzano Decimo presents excellent opportunities for large-scale solar photovoltaic installations. The most suitable areas for solar development would be the expansive agricultural plains extending south and southeast of the town, where the terrain remains consistently level and unobstructed by significant elevation changes or natural barriers.

Areas with minimal existing infrastructure development offer the greatest potential for solar farms, particularly the open agricultural zones between Azzano Decimo and the communities of Fiume Veneto and Chions. These locations benefit from the region's characteristic flat terrain while maintaining adequate distance from residential areas and major transportation routes.

The agricultural plains extending toward Pordenone and beyond provide additional promising sites, especially where large contiguous parcels of land could accommodate extensive solar arrays. The consistent topography in these areas eliminates concerns about shading from hills or mountains, while the existing rural road network would facilitate construction and maintenance access.

Areas closer to existing electrical infrastructure, such as the industrial zones around Pordenone or along major transportation corridors, would offer advantages for grid connection while still benefiting from the region's favorable flat topography. The absence of significant topographical obstacles throughout much of this area means that solar installations could be oriented optimally without concern for terrain-related shading or access difficulties.
