Verdellino, Lombardy, Italy, situated at 45.6019° N latitude and 9.6041° E longitude, presents a varied landscape for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal fluctuations in solar power output, which impacts the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
The solar energy production in Verdellino follows a predictable pattern aligned with the changing seasons. Summer stands out as the most productive period, with an impressive daily output of 6.75 kWh per kW of installed solar capacity. Spring follows as the second most productive season, generating 5.40 kWh per day. Autumn sees a considerable drop in production to 3.12 kWh per day, while winter experiences the lowest output at 1.85 kWh per day.
These figures highlight the substantial variation in solar energy generation throughout the year. The peak production during summer months makes it an ideal time for maximizing solar energy harvesting. Spring and early autumn also offer favorable conditions for solar power generation.
Optimal Panel Installation
To maximize year-round solar energy production in Verdellino, Lombardy, fixed solar panels should be installed at a tilt angle of 39 degrees facing south. This angle has been calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the location's latitude and the Earth's elliptical orbit.
Environmental and Weather Considerations
While Verdellino's location is generally favorable for solar energy production, there are some environmental and weather factors that could potentially impact solar panel efficiency:
- Fog and haze: The Po Valley region, where Verdellino is located, is prone to fog and haze, especially during autumn and winter. This can reduce solar irradiance reaching the panels.
- Snow: Winter snowfall, though not extremely frequent, can temporarily cover panels and reduce energy production.
To mitigate these challenges, consider implementing the following measures:
- Use anti-reflective coatings on solar panels to improve light absorption in foggy conditions.
- Install panels at a steeper angle to facilitate snow sliding off more easily.
- Implement a regular cleaning schedule to remove any accumulated dust or debris, especially after foggy or snowy periods.
Despite these potential challenges, Verdellino remains a viable location for solar energy production, particularly during the spring and summer months. With proper installation and maintenance, a solar PV system can effectively harness the available solar resources throughout the year.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 39° South in Verdellino, Italy
To maximize your solar PV system's energy output in Verdellino, Italy (Lat/Long 45.6019, 9.6041) 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 Verdellino, 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 Verdellino, 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 Verdellino, 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 Verdellino, 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 Verdellino, Italy
The area around Verdellino, Italy, is characterized by a diverse topography typical of the Lombardy region. Verdellino itself is situated in a relatively flat area known as the Po Valley, or Pianura Padana in Italian. This valley is one of the largest and most important plains in Italy, stretching across much of the northern part of the country.
To the north of Verdellino, the terrain gradually begins to rise as it approaches the foothills of the Alps. These hills, known as the Prealps, create a picturesque backdrop to the otherwise flat landscape. The transition from the plain to the hills is gradual, with gentle slopes and rolling countryside.
To the south and east, the landscape remains predominantly flat, with occasional small hills and river valleys breaking up the monotony of the plain. The area is crisscrossed by numerous rivers and streams, including the nearby Brembo River, which have shaped the local topography over millennia.
When considering areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, the flat areas of the Po Valley offer the most promise. These open, expansive spaces provide ideal conditions for solar farms, with few natural obstacles to block sunlight. The areas to the south and east of Verdellino, where the terrain remains largely flat, would be particularly well-suited.
However, it's important to note that the Po Valley is also prime agricultural land, so there may be competing interests for land use. Any large-scale solar projects would need to be carefully planned to balance energy production with agricultural needs.
The hilly areas to the north, while potentially offering some south-facing slopes that could be good for solar panels, are generally less suitable for large-scale installations due to the more complex terrain and potential shading issues from neighboring hills.
In conclusion, the most promising areas for large-scale solar PV near Verdellino would be the flat, open spaces of the Po Valley to the south and east of the town, where the combination of favorable topography and ample sunlight could support efficient solar energy production.
