Solar PV Analysis of San Germano Vercellese, Italy
San Germano Vercellese, Piedmont, Italy, located in the Northern Temperate Zone is a decent location for generating solar energy year-round. However, the amount of energy that can be produced varies significantly depending on the season.
In summer, you can generate about 6.75 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar power. This is a good amount and makes summer an ideal time to generate solar power at this location.
Autumn sees a decrease in production to about 3.12 kWh/day per kW of installed solar power. This is less than half of what you could produce in summer but still enough to make it worthwhile.
Winter has the lowest production with only 1.85 kWh/day per kW of installed solar power being generated. The short days and low sun position during winter reduces the effectiveness of solar panels significantly.
Spring sees an increase again with around 5.40 kWh/day per kW of installed solar power being generated - making it another good season for generating electricity from sunlight.
For fixed panel installations at this location, tilting panels at an angle of 39 degrees towards the south will maximize total year-round production from your PV system since it aligns better with the sun's path across the sky throughout different seasons.
As far as environmental factors are concerned that might affect your PV system's performance, San Germano Vercellese experiences temperate weather which might not pose significant challenges to your installation; however local weather patterns like cloud cover or fog could potentially reduce output on certain days or periods throughout the year – something you should keep in mind when considering overall yearly yield estimates based on average seasonal values given above.
Topographically speaking if there are hills or other structures that cast shadows over where you plan to install your panels they could also impact overall performance by blocking direct sunlight especially during low sun angles seen in winter months; therefore choosing unobstructed location is important.
To ensure greater energy production, you can take measures like regular cleaning of solar panels to remove dust or debris that may accumulate and block sunlight. Also, installing a tracking system that follows the sun's path across the sky can help maximize exposure to sunlight throughout the day, increasing overall energy production especially during less than ideal seasons.
In conclusion, while San Germano Vercellese isn't the absolute best location for solar power generation due to its varying seasonal output and potential local weather patterns impacting performance; it still offers decent yearly output especially if panels are installed at optimal tilt angle and site is chosen with care avoiding potential shading obstacles.
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 San Germano Vercellese
Seasonal solar PV output for Latitude: 45.35, Longitude: 8.2439 (San Germano Vercellese, 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 San Germano Vercellese, Italy
To maximize your solar PV system's energy output in San Germano Vercellese, Italy (Lat/Long 45.35, 8.2439) 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 San Germano Vercellese, 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 San Germano Vercellese, 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 | 59° 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 San Germano Vercellese, 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 San Germano Vercellese, 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 San Germano Vercellese, Italy
San Germano Vercellese is located in the Piedmont region of Italy, which is characterized by a combination of flat plains, rolling hills, and mountainous regions. The town itself lies in the plains area known as the Po Valley.
The topography surrounding San Germano Vercellese consists mainly of flat agricultural land with some small hills. The region has an average altitude of around 130 meters above sea level. It is surrounded by several rivers including Sesia and Cervo which contribute to its fertile lands.
In terms of solar photovoltaic (PV) potential, areas with flat or gently sloping terrain would be most suitable for large-scale solar installations as they provide maximum exposure to sunlight and ease installation process. Therefore, the vast agricultural lands around San Germano Vercellese could be prime locations for such projects.
However, it's important to note that suitability for solar PV doesn't solely depend on topography but also on factors like local climate (amount of sunshine), land use regulations and environmental considerations. Therefore any decision on where to place large scale solar PV should take into account these factors as well.
Furthermore, rooftops in urban areas or industrial zones could also be used for smaller-scale installations or community solar projects. These can have less impact on land use while still contributing significantly to renewable energy production.
A detailed site survey and feasibility study would ultimately determine the best locations for large-scale solar PV near San Germano Vercellese.
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. This means that 8.30% of Italy's total energy as a country comes from solar PV (that's 8th in the world). Each year Italy is generating 381 Watts from solar PV per capita (Italy ranks 7th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Italy?
Yes, there are several incentives for businesses wanting to install solar energy in Italy. The Italian government offers a range of financial incentives and tax credits for businesses that install solar energy systems.
