San Martino Alfieri, Piedmont, Italy is a decent location for generating solar energy throughout the year. The amount of electricity that can be produced from solar panels varies by season, with the highest output in summer (7.15kWh/day) and lowest in winter (1.94kWh/day). Spring and autumn produce moderate amounts of electricity.
The best time to generate solar power at this location is during the summer when the sun's rays are strongest and longest lasting. Even though power production drops off significantly in autumn and especially in winter, there's still a reasonable amount generated during spring.
To get the most out of your solar panels year-round at this location, you should install them at an angle of 38 degrees facing south. This position will allow them to capture as much sunlight as possible over different seasons.
While San Martino Alfieri has good potential for solar energy production, some local factors could affect it. For instance, weather conditions like heavy snowfall or fog could block sunlight and reduce power generation from your panels; also trees or buildings might cast shadows on your installation site reducing its efficiency.
To deal with these issues:
- Regularly clean off any snow or debris on your panels.
- Consider installing tracking systems that adjust panel angles throughout the day to ensure they're always facing directly towards the sun.
- If possible choose an installation site with minimal shading from nearby structures or vegetation.
Remember: even if you can't completely eliminate these obstacles, just reducing their impact can make a significant difference in how much energy you generate overall!
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 Martino Alfieri
Seasonal solar PV output for Latitude: 44.8188, Longitude: 8.1043 (San Martino Alfieri, 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 38° South in San Martino Alfieri, Italy
To maximize your solar PV system's energy output in San Martino Alfieri, Italy (Lat/Long 44.8188, 8.1043) throughout the year, you should tilt your panels at an angle of 38° 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 Martino Alfieri, 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 Martino Alfieri, Italy. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° 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 | 48° South in Autumn | 59° South in Winter | 37° 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 Martino Alfieri, 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 Martino Alfieri, 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 Martino Alfieri, Italy
San Martino Alfieri is located in the Piedmont region of Italy. The area is characterized by a mix of flat plains and hilly terrain, with vineyards and farmlands dominating the landscape.
The topography around San Martino Alfieri can be described as relatively flat to gently rolling hills. The area is part of the larger Po Valley region, which is largely flat, but it's also surrounded by some hillier regions like Langhe and Monferrato.
When considering large-scale solar PV installations, ideally you want areas that are relatively flat or have gentle slopes facing south for maximum sun exposure. In addition, these sites should not be shaded by trees or other structures and should be close to existing power lines for easy connection to the grid.
In this case, looking at satellite imagery and topographical maps of the area around San Martino Alfieri, it appears that there are several areas that could potentially meet these criteria. Particularly some parts of nearby plains or agricultural lands could be suitable if they're not being actively used for farming.
However, specific suitability would require detailed site surveys including analysis on local weather patterns (like cloud cover), soil conditions (for installing solar panel mounts), proximity to electrical infrastructure etc., along with negotiations with landowners if needed.
Additionally environmental impact assessments would need to be conducted as well particularly given this region's rich biodiversity & cultural heritage sites (like castles). For example vineyard landscapes in nearby regions like Langhe-Roero & Monferrato have been designated as UNESCO World Heritage Sites due their unique cultural value & history related to wine production.
Finally any such developments would need comply with local/ regional planning regulations which may have restrictions regarding land use changes especially in scenic/ culturally significant areas like Piedmont.
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. These include the Conto Energia scheme, which provides feed-in tariffs for electricity generated from renewable sources; the Superbonus 110%, which allows businesses to deduct up to 110% of their investment in renewable energy systems from their taxes; and the Ecobonus 65%, which provides a 65% tax deduction on investments in renewable energy systems. Additionally, businesses may be eligible for grants or loans from regional governments or other organizations.
