Solar PV Analysis of Salerno, Italy
The location at Salerno, Campania, Italy is decent for generating energy through solar panels year-round, but it's not perfect. The amount of energy you can get from the sun varies throughout the year. In summer, you can expect to generate about 7.74 kilowatt-hours (kWh) per day for every kilowatt (kW) of solar panels you have installed. This drops to 3.65 kWh/day in autumn and further decreases to 2.42 kWh/day in winter before rising again to 6.15 kWh/day in spring.
This means that the best times of year for generating solar power at this location are during the summer and spring when sunlight is more abundant and direct.
To maximize your total annual energy production from these solar panels, they should be tilted at an angle of 34 degrees facing south if they are fixed and cannot move or adjust their position throughout the day or year.
There could be several local factors that might affect your ability to generate solar power here though such as buildings or mountains blocking sunlight, heavy cloud cover or pollution reducing the intensity of sunlight reaching your panels, or even dust and dirt accumulating on your panels which reduces their efficiency.
To counteract these potential issues:
1) Try installing your solar panels where they will get unobstructed sunlight for most of the day.
2) Regularly clean off any dust or dirt on your panels.
3) Consider using a tracking system that allows your panels to follow the sun's path across the sky instead of being fixed in one position.
4) If air pollution is a significant issue in this area affecting visibility/sunlight intensity then consider other renewable sources like wind turbines if feasible.
Remember though that while these steps can help increase production, none can completely eliminate all challenges related with producing solar power especially during seasons with less sunshine like autumn and winter.
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 Salerno
Seasonal solar PV output for Latitude: 40.6611, Longitude: 14.8052 (Salerno, 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 34° South in Salerno, Italy
To maximize your solar PV system's energy output in Salerno, Italy (Lat/Long 40.6611, 14.8052) throughout the year, you should tilt your panels at an angle of 34° 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 Salerno, 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 Salerno, Italy. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 24° 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 Salerno, 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 Salerno, 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 Salerno, Italy
Salerno, Italy is located in the Campania region of Southern Italy. The topography around Salerno is diverse, with coastal plains transitioning into hilly and mountainous terrain as one moves inland. The city itself is situated on the Gulf of Salerno, with the Tyrrhenian Sea to its west.
The coastal areas are relatively flat and could potentially be suitable for large-scale solar PV installations. However, it's important to consider that these areas are also densely populated and developed which might limit available space for such projects.
The hilly and mountainous regions offer a lot of sunlight exposure due to their elevation but could pose challenges in terms of installation due to the uneven terrain. It's also crucial to consider environmental impact as these areas often have rich biodiversity.
The most suitable places would likely be flat agricultural lands or industrial zones where land use conflicts are minimized. A specific assessment would be needed though, taking into account factors like solar irradiance levels (which are generally high in this Mediterranean region), land use/availability, proximity to power grids and local regulations regarding renewable energy projects.
In terms of actual locations near Salerno that might be suitable for large-scale solar PV installations, one potential area could be the Pontecagnano Faiano municipality located south-east from Salerno which has some flatter lands used mainly for agriculture.
However, any potential site would need a detailed analysis including not only physical factors but also social acceptance issues as well as economic feasibility studies before proceeding with a project like this.
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.
