Senago, Lombardy, Italy, situated at 45.5722°N, 9.1245°E, presents a moderately favorable location for solar PV energy generation throughout the year. This Northern Italian town experiences significant seasonal variations in solar output, reflecting its position in the Northern Temperate Zone.
Seasonal Solar Performance
Summer stands out as the peak season for solar energy production in Senago, Lombardy, with an impressive daily output of 6.75 kWh per kW of installed solar capacity. Spring follows closely, generating 5.40 kWh/day. However, autumn and winter see a substantial decrease in solar efficiency, with outputs of 3.12 kWh/day and 1.85 kWh/day, respectively.
The most ideal times for solar generation in Senago are from late spring through early autumn. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. Conversely, the winter months present challenges due to shorter days and lower sun angles, resulting in reduced energy production.
Optimal Panel Installation
For fixed panel installations in Senago, Lombardy, the ideal tilt angle to maximize year-round solar production is 39 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun positions across seasons.
Environmental and Weather Considerations
While Senago's climate is generally conducive to solar energy production, there are some factors that could potentially impact solar panel efficiency:
- Fog and haze: The Po Valley, where Senago is located, is prone to fog, especially in autumn and winter. This can reduce solar irradiance reaching the panels.
- Snow: Although not frequent, occasional snowfall in winter can temporarily cover panels, reducing their output.
To mitigate these issues, consider the following preventative measures:
- Install panels at a steeper angle to promote snow sliding off and to maximize winter sun exposure.
- Use anti-reflective coatings on panels to improve performance in low-light conditions caused by fog or haze.
- Implement a regular cleaning schedule to remove any debris or snow accumulation.
By addressing these factors and optimizing panel placement, Senago can effectively harness its solar potential, particularly during the more productive spring and summer months.
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 Senago
Seasonal solar PV output for Latitude: 45.5722, Longitude: 9.1245 (Senago, 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 Senago, Italy
To maximize your solar PV system's energy output in Senago, Italy (Lat/Long 45.5722, 9.1245) 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 Senago, 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 Senago, 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 Senago, 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 Senago, 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 Senago, Italy
The area around Senago, Italy, is characterized by relatively flat terrain typical of the Po Valley (Pianura Padana) region. This part of northern Italy is known for its expansive lowlands, which stretch from the foothills of the Alps in the north to the Apennine Mountains in the south. Senago itself is situated in the northwestern part of this plain, just north of Milan.
The topography in and around Senago is predominantly level, with only subtle variations in elevation. The landscape is largely urbanized and agricultural, with a mix of residential areas, industrial zones, and farmland. Small streams and irrigation channels crisscross the region, but there are no significant hills or valleys in the immediate vicinity.
To the north and west of Senago, the terrain gradually begins to rise as it approaches the Alpine foothills, but this change in elevation is not dramatic within the close proximity of the town. To the south and east, the flat plain continues for many kilometers, encompassing the greater Milan metropolitan area.
Regarding areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, the flat nature of the Po Valley presents several potential opportunities. The most suitable locations would likely be found in the agricultural areas surrounding Senago and other nearby towns. These open spaces offer the advantage of minimal shading and the possibility of large, uninterrupted arrays of solar panels.
Ideal sites for solar PV would be non-productive or marginal agricultural land that is not crucial for food production. Areas to the south of Senago might be particularly appealing, as they would have unobstructed southern exposure, which is optimal for solar energy generation in the Northern Hemisphere.
However, it's important to note that the Po Valley is known for its frequent fog and haze, especially during winter months. This could potentially reduce the efficiency of solar installations. Additionally, the high level of urbanization and the valuable agricultural land in the region might pose challenges in finding suitable large areas for solar farms. Any large-scale solar project would need to carefully balance energy production goals with land use considerations and local 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.
