Solar PV Analysis of San Marcellino, Italy
San Marcellino, Campania, Italy is a fairly good location for generating energy through solar photovoltaic (PV) systems throughout the year. This is due to its position in the Northern Temperate Zone where it receives a decent amount of sunlight.
In simple terms, the energy that can be produced from solar panels installed here varies with each season. In Summer and Spring, you can expect more energy production because these seasons have longer daylight hours and more direct sunlight - specifically about 7.74 kilowatt-hours per day in Summer and 6.15 kilowatt-hours per day in Spring for each kilowatt of solar installed.
However, during Autumn and Winter, the output will be less due to shorter days and less intense sunlight - about 3.65 kilowatt-hours per day in Autumn and only 2.42 kilowatt-hours per day in Winter for each kilowatt of solar installed.
To get the most out of your solar panels year-round at this location, they should ideally be tilted at an angle of 35 degrees facing South. This allows them to catch as much sunlight as possible throughout different times of the year.
As for potential issues that could hinder solar production at this location: San Marcellino is located near mountains which could potentially cast shadows on panels depending on their exact placement; weather conditions such as cloud cover or fog could also reduce sun exposure occasionally; dust or dirt accumulation on panels might limit their efficiency too.
To mitigate these factors: ensure your installation site is clear from any obstructions like trees or buildings that may cast shadows over time; regular cleaning maintenance will help keep dust off panels ensuring they operate efficiently; monitor local weather patterns to understand how they may affect your system's performance so you can adjust accordingly if necessary.
Overall though, despite some seasonal fluctuations and potential environmental considerations, San Marcellino offers a solid opportunity for harnessing solar power effectively throughout most parts of the year.
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 Marcellino
Seasonal solar PV output for Latitude: 40.9897, Longitude: 14.1677 (San Marcellino, 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 35° South in San Marcellino, Italy
To maximize your solar PV system's energy output in San Marcellino, Italy (Lat/Long 40.9897, 14.1677) throughout the year, you should tilt your panels at an angle of 35° 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 Marcellino, 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 Marcellino, Italy. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 25° South in Summer | 44° South in Autumn | 55° South in Winter | 33° 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 Marcellino, 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 Marcellino, 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 Marcellino, Italy
San Marcellino is located in the Campania region of southern Italy, not far from Naples. The topography of this area is characterized by hilly terrain with fertile plains and valleys interspersed between mountainous regions. The region benefits from a Mediterranean climate with plenty of sunshine throughout the year.
Given these characteristics, large scale solar photovoltaic (PV) installations could potentially be suited to several types of locations in or near San Marcellino:
1. Plains and Valleys: These areas are relatively flat and open, making them suitable for ground-mounted solar PV systems. However, any development would need to consider local agricultural practices and land use restrictions.
2. Hillside Terraces: In hilly areas where terracing has been used for agriculture or other purposes, these terraces might be adapted for solar PV installation. This would require careful planning to avoid erosion or other environmental impacts.
3. Rooftops: In urbanized areas like San Marcellino itself or nearby Naples, rooftops represent a significant opportunity for solar PV installation without requiring additional land resources.
4. Brownfield Sites: Any disused industrial sites in the region could be repurposed as locations for solar power installations.
5. Floating Solar: If there are any large bodies of water nearby such as reservoirs or lakes (not directly near San Marcellino but could be an option within Campania), floating solar PV systems could also be considered.
The exact suitability of each location would depend on more detailed analysis including sunlight exposure (insolation), land use restrictions, local infrastructure and grid connectivity among other factors.
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.
