Turi, Apulia, Italy, located in the Northern Temperate Zone, offers a promising location for solar PV energy generation throughout the year. This picturesque town in southern Italy experiences varying levels of solar potential across different seasons, presenting both opportunities and challenges for solar energy production.
Seasonal Solar Performance
The solar energy output in Turi fluctuates significantly across seasons. Summer stands out as the most productive period, with an impressive 7.71 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second-best season, generating 5.98 kWh/day. Autumn sees a notable decrease in production at 3.66 kWh/day, while winter experiences the lowest output at 2.52 kWh/day.
These figures indicate that Turi is particularly well-suited for solar energy generation during the warmer months, from late spring through early autumn. This period offers extended daylight hours and typically clearer skies, maximizing solar panel efficiency.
Optimal Panel Installation
To achieve the best year-round solar energy production in Turi, Apulia, fixed solar panels should be installed at a tilt angle of 35 degrees facing south. This angle has been calculated to optimize energy capture across all seasons, taking into account the town's latitude and the Earth's orbit.
Environmental Considerations
While Turi generally provides favorable conditions for solar energy production, there are a few environmental factors to consider:
- Dust and pollen: Turi's rural setting may lead to dust and pollen accumulation on solar panels, potentially reducing their efficiency. Regular cleaning and maintenance can mitigate this issue.
- Occasional cloudy days: Though infrequent, cloudy weather can temporarily decrease solar output. Using high-efficiency panels can help maximize energy production even in less-than-ideal conditions.
By addressing these minor challenges through proper installation techniques and regular maintenance, solar PV systems in Turi can operate at high efficiency, making the most of the abundant sunshine this Italian town receives throughout the year.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Turi
Seasonal solar PV output for Latitude: 40.9166, Longitude: 17.0188 (Turi, 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 Turi, Italy
To maximize your solar PV system's energy output in Turi, Italy (Lat/Long 40.9166, 17.0188) 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 Turi, 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 Turi, 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 | 45° 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 Turi, 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 Turi, 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 Turi, Italy
The area surrounding Turi, Italy, located at approximately 40.9166°N latitude and 17.0188°E longitude, is characterized by a diverse and picturesque topography typical of the Puglia region in southern Italy. This charming town is situated in the heart of the Murge plateau, a limestone-rich area that extends across much of central Puglia. The landscape around Turi is predominantly hilly, with gentle slopes and rolling terrain that gradually rises from the coastal plains to the east. The elevation in this area ranges from about 200 to 400 meters above sea level, providing a mix of flat areas and more elevated regions. The hills are often terraced, a testament to centuries of agricultural practices that have shaped the land. Interspersed throughout the countryside are numerous olive groves and vineyards, which are iconic features of the Puglian landscape. These cultivated areas are punctuated by patches of Mediterranean scrubland, known as macchia, consisting of low-growing shrubs and hardy plants adapted to the region's hot, dry summers.
Potential for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would combine ample sunlight exposure, relatively flat terrain, and minimal environmental impact. The coastal plains to the east of Turi, stretching towards the Adriatic Sea, offer promising potential for solar PV development. These areas are generally flatter and receive abundant sunshine throughout the year. The land here is less agriculturally productive compared to the fertile hills around Turi, making it a more suitable candidate for solar farms without significantly impacting food production. Another promising area lies to the west and southwest of Turi, where the terrain becomes more open and less densely populated. These regions, part of the broader Murge plateau, feature expansive areas of relatively flat or gently sloping land that could accommodate large solar installations. The natural vegetation in these areas is often sparse, reducing potential conflicts with biodiversity conservation efforts. It's important to note that any large-scale solar PV project would need to carefully consider local zoning regulations, environmental impact assessments, and community engagement. The rich cultural heritage and traditional land use patterns of the region would need to be respected in the planning and implementation of such projects. In conclusion, while the immediate vicinity of Turi may not be ideal for large-scale solar PV due to its hilly terrain and agricultural importance, the surrounding regions offer promising alternatives. The coastal plains to the east and the more open areas to the west and southwest present opportunities for sustainable energy development that could harness the abundant sunshine of southern Italy.Italy solar PV Stats as a country
