Solar PV Analysis of Treviso, Italy
Treviso, Veneto, Italy, situated at coordinates 45.6618°N, 12.2428°E, presents a mixed picture for solar energy generation throughout the year. Located in the Northern Temperate Zone, this charming Italian city experiences distinct seasonal variations that significantly impact solar PV output.
Seasonal Solar Performance
The solar energy potential in Treviso fluctuates considerably across the seasons. Summer stands out as the most productive period, with an impressive daily output of 7.08 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 5.46 kWh/day. Autumn sees a notable decrease to 3.29 kWh/day, while winter experiences the lowest production at 1.72 kWh/day.
These figures indicate that Treviso is particularly well-suited for solar energy generation during the warmer months, from late spring through early autumn. This period offers longer daylight hours and more direct sunlight, maximizing solar panel efficiency.
Optimal Panel Installation
To maximize year-round solar production in Treviso, Veneto, fixed solar panels should be installed at a tilt angle of 39 degrees facing south. This angle is calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the city's latitude and the Earth's elliptical orbit.
Environmental and Weather Considerations
While Treviso's location is generally favorable for solar energy, there are some environmental factors to consider. The region experiences occasional fog and haze, particularly in autumn and winter, which can temporarily reduce solar panel efficiency. Additionally, the area is prone to sporadic hailstorms during summer, posing a potential risk to solar installations.
To mitigate these challenges, several preventative measures can be implemented:
- Use high-quality, hail-resistant solar panels to protect against potential storm damage.
- Install a reliable cleaning system to remove dust and debris, ensuring optimal panel performance.
By addressing these factors, solar installations in Treviso can maintain higher energy production levels throughout the year, making the most of the city's solar potential despite seasonal variations.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 338 locations across Italy. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Treviso
Seasonal solar PV output for Latitude: 45.6618, Longitude: 12.2428 (Treviso, 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 Treviso, Italy
To maximize your solar PV system's energy output in Treviso, Italy (Lat/Long 45.6618, 12.2428) 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 Treviso, 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 Treviso, 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 Treviso, 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 Treviso, Italy.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Treviso, Italy
The area around Treviso, Italy, is characterized by a predominantly flat landscape. This region, known as the Venetian Plain or Po Valley, is one of the largest and most important lowland areas in Italy. The terrain is generally level, with only slight variations in elevation across much of the surrounding countryside.
To the north of Treviso, the land gradually begins to rise as it approaches the foothills of the Alps. This transition zone, called the Prealps, features gently rolling hills and slightly more varied topography. However, these elevations are still relatively modest compared to the more dramatic mountain ranges further north.
To the east and southeast of Treviso, the land remains flat as it extends towards the Adriatic Sea. This area is characterized by expansive agricultural fields, interspersed with small towns and villages. Numerous rivers and canals crisscross the landscape, including the Sile River, which flows through Treviso itself.
For large-scale solar PV installations, the areas most suited would likely be found in the flat, open spaces to the south and southeast of Treviso. These locations offer several advantages for solar energy production:
- Abundant open land with minimal shading from natural features or buildings
- Relatively uniform terrain, reducing construction and maintenance costs
- Good road access for transportation of materials and equipment
- Proximity to existing power infrastructure in the densely populated Veneto region
The agricultural areas between Treviso and Venice, as well as those extending towards Padua and Rovigo, could be particularly suitable for solar farms. These regions receive ample sunlight throughout the year and have large, unobstructed spaces that could accommodate extensive arrays of solar panels.
It's worth noting that while the flat terrain is advantageous for solar PV installation, careful consideration would need to be given to potential flooding risks, as parts of the Venetian Plain are prone to periodic inundation. Additionally, the use of productive agricultural land for solar farms would need to be balanced against food production needs and local land-use regulations.
Italy solar PV Stats as a country
Italy ranks 6th in the world for cumulative solar PV capacity, with 22,698 total MW's of solar PV installed.
