Thiene, Italy presents a moderately favorable location for solar PV energy generation, though with significant seasonal variation typical of its Northern Temperate Zone position at coordinates 45.7411°N, 11.4486°E.

Seasonal Solar Performance

The solar energy output shows substantial differences throughout the year. Summer delivers the strongest performance at 6.82 kWh per day per kW of installed capacity, making it the prime season for solar generation. Spring follows as the second-best period with 5.29 kWh daily output, offering excellent solar conditions as daylight hours increase and weather improves. Autumn sees a notable decline to 3.15 kWh per day, while winter presents the most challenging conditions with only 1.79 kWh daily output per kW installed. This dramatic seasonal swing means solar systems will produce nearly four times more energy in summer compared to winter months. For optimal year-round performance, fixed solar panels should be tilted at 39 degrees facing south. This angle maximizes total annual energy production by accounting for the sun's varying position throughout the year and the location's specific latitude.

Local Factors Affecting Solar Production

Several environmental and weather factors in the Thiene area can impact solar panel efficiency:

• Fog and mist: The Veneto region experiences frequent fog, particularly during autumn and winter months, which can significantly reduce solar irradiance
• Air pollution: Being in an industrialized area of northern Italy, airborne particles can accumulate on panels, reducing light transmission
• Snow accumulation: Winter snowfall can completely block panels until cleared
• Dust and pollen: Agricultural activities and seasonal pollen can create film buildup on panel surfaces

Preventative Installation Measures

To maximize energy production despite these challenges, several installation strategies prove effective. Regular cleaning systems or easy access for manual cleaning helps combat dust, pollen, and pollution buildup. The recommended 39-degree tilt angle naturally assists with snow shedding and rain washing. Installing panels with adequate spacing allows for proper air circulation and easier maintenance access. Anti-reflective coatings can help maintain efficiency even when atmospheric conditions aren't ideal. Monitoring systems enable quick identification of performance drops due to environmental factors. Overall, while Thiene faces typical northern Italian weather challenges, proper installation techniques and maintenance can ensure reliable solar energy production, with summer and spring months providing particularly strong generation potential.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

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

Seasonal solar PV output for Latitude: 45.7411, Longitude: 11.4486 (Thiene, 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 Thiene, Italy

To maximize your solar PV system's energy output in Thiene, Italy (Lat/Long 45.7411, 11.4486) 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 Thiene, 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 Thiene, 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 Thiene, 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 Thiene, 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 Thiene, Italy

Topographical Features Around Thiene

Thiene sits in the heart of the Veneto region in northern Italy, positioned within the broad Po Valley plain that stretches across much of northern Italy. The landscape around this historic town is characterized by relatively flat to gently rolling terrain, making it part of one of Europe's most extensive lowland areas. The elevation in and around Thiene typically ranges from about 100 to 200 meters above sea level, creating a predominantly level topography that extends for kilometers in most directions.

To the north of Thiene, the terrain gradually begins to rise as it approaches the foothills of the Italian Alps. The Asiago Plateau lies roughly 30 kilometers to the north, where elevations increase more dramatically. However, the immediate vicinity around Thiene remains relatively flat, with only gentle undulations breaking up the otherwise uniform landscape. Small waterways and irrigation channels crisscross the area, remnants of centuries of agricultural development that has shaped this fertile plain.

The surrounding countryside is predominantly agricultural, featuring a patchwork of cultivated fields, vineyards, and scattered farmsteads. This rural character extends in all directions from the town center, with only occasional clusters of residential or industrial development interrupting the agricultural landscape. The terrain lacks significant natural barriers such as steep hills or dense forests that might complicate large-scale development projects.

Optimal Areas for Large-Scale Solar Development

The flat to gently rolling topography surrounding Thiene presents excellent opportunities for large-scale solar photovoltaic installations. The most suitable areas would be the open agricultural plains extending south and east of the town, where the terrain is most consistently level and free from significant obstructions. These areas benefit from minimal shading from hills or mountains, particularly important for maximizing solar panel efficiency throughout the day.

The agricultural fields immediately southeast of Thiene offer particularly promising sites, as this direction provides optimal solar orientation while maintaining the flat terrain characteristics ideal for solar farms. The land in this area is relatively open, with fewer scattered buildings or infrastructure that might create shading issues or complicate installation logistics.

Areas to the southwest also present good opportunities, where the landscape remains predominantly flat and agricultural. The absence of significant elevation changes in these directions means that large solar installations could be developed without the need for extensive grading or terrain modification, reducing both construction costs and environmental impact.

The northern areas, while still relatively flat in the immediate vicinity of Thiene, gradually transition toward more varied topography as they approach the Alpine foothills. While not unsuitable for solar development, these areas might present more challenges due to occasional rolling hills and the potential for increased shading during certain times of the year when the sun angle is lower.

The western plains also offer suitable conditions for solar development, though careful site selection would be important to avoid areas with higher concentrations of existing residential or commercial development. The flat terrain and agricultural character of much of this area make it technically feasible for large-scale solar installations, provided appropriate land use agreements can be established with local agricultural interests.
