Solar PV Analysis of Bari, Italy
Bari, Apulia, Italy is a decent location for generating energy through solar photovoltaic (PV) panels, but it's not the best. The amount of electricity that can be produced varies throughout the year. During summer and spring, the sun shines more often and longer, allowing for higher production rates of 7.24 kilowatt-hours per day in summer and 5.91 kilowatt-hours per day in spring per kilowatt of installed solar capacity.
In contrast, during autumn and winter when there are fewer hours of sunlight each day, less energy can be produced - about 3.52 kWh/day in fall and just 2.27 kWh/day in winter per kW of installed solar capacity.
To get the most out of your solar panels throughout the year at this location, you should ideally tilt them at an angle facing towards south by approximately 35 degrees from horizontal level to maximise total year-round production from solar PV system.
As far as environmental or local factors go that could potentially impede or reduce how much energy you're able to generate with your solar panels here in Bari: weather conditions like heavy cloud cover or storms could block sunlight; pollution might also affect sunlight penetration; buildings or trees may cast shadows on your panels too.
Preventative measures to ensure greater energy production include installing your system where it will receive maximum exposure to direct sunlight throughout the day without being obstructed by shadows from nearby objects such as buildings or trees; regularly cleaning dusts off panel surfaces would help maintain their efficiency too; if air pollution is a concern then using anti-reflective coating on panel surface might help capture more light under hazy conditions.
Overall though, while not perfect all-year-round due to seasonal variations in sunshine hours especially during winter months when less daylight available for power generation compared with other seasons like summer time which has longest daylight hours hence best period for highest output potential – Bari still offers a relatively good site for solar power generation.
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 Bari
Seasonal solar PV output for Latitude: 41.1122, Longitude: 16.8547 (Bari, 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 Bari, Italy
To maximize your solar PV system's energy output in Bari, Italy (Lat/Long 41.1122, 16.8547) 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 Bari, 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 Bari, 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 Bari, 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 Bari, 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 Bari, Italy
Bari, Italy is located in the Puglia region on the Adriatic Sea. The topography of this area is largely flat or gently rolling plains, with some low hills. This makes it ideally suited for large-scale solar photovoltaic (PV) installations.
The surrounding areas best suited for large-scale solar PV would be those with high levels of sunlight and open, flat spaces. Considering these factors, regions towards the inland like Bitonto, Modugno or even further away places like Foggia could be suitable due to their relatively flatter terrains and good exposure to sunlight.
Furthermore, agricultural lands that are not currently in use could also be potential sites for solar farms as they often have minimal shading and obstruction issues.
However, any decision about installing a large-scale solar PV system should consider other factors too such as local regulations related to land use and environmental impact; proximity to transmission lines or substations; land cost; among others.
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.
