Annone Veneto, Italy, situated at latitude 45.7927 and longitude 12.6783, presents a mixed picture for solar PV energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar energy production, which impacts the overall efficiency of solar installations.
Seasonal Solar Performance
The solar energy output at Annone Veneto varies considerably across the seasons:
- Summer: 7.05 kWh/day per kW installed
- Spring: 5.41 kWh/day per kW installed
- Autumn: 3.22 kWh/day per kW installed
- Winter: 1.66 kWh/day per kW installed
Optimal Panel Installation
For fixed panel installations in Annone Veneto, the ideal tilt angle to maximize year-round solar production is 39 degrees facing South. This angle is calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the Earth's elliptical orbit and the location's specific latitude.
Environmental and Weather Factors
While Annone Veneto doesn't face extreme environmental challenges for solar production, there are some factors to consider: 1. Fog and low-lying clouds: The Po Valley, where Annone Veneto is located, is prone to fog, especially in autumn and winter. This can reduce solar irradiance and impact energy production. 2. Snow: Although not frequent, occasional snowfall in winter can temporarily cover panels, reducing their efficiency.
Preventative Measures
To mitigate these factors and ensure greater energy production: 1. Install panels at the optimal angle of 39 degrees to help snow slide off more easily. 2. Use anti-reflective coatings on panels to improve performance in low-light conditions caused by fog. 3. Implement a regular cleaning schedule, especially after snowfall or during foggy periods, to maintain panel efficiency.
In conclusion, while Annone Veneto is not ideal for year-round solar energy production due to significant seasonal variations, proper installation and maintenance can still make solar PV a viable energy option, especially during the more productive summer and spring months.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Seasonal solar PV output for Latitude: 45.7927, Longitude: 12.6783 (Annone Veneto, 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 39° South in Annone Veneto, Italy
To maximize your solar PV system's energy output in Annone Veneto, Italy (Lat/Long 45.7927, 12.6783) throughout the year, you should tilt your panels at an angle of 39° 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 Annone Veneto, 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 Annone Veneto, Italy. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° 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 | 49° South in Autumn | 60° South in Winter | 38° 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 Annone Veneto, 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 Annone Veneto, 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 Annone Veneto, Italy
The area surrounding Annone Veneto, located in northeastern Italy, is characterized by a predominantly flat landscape typical of the Venetian Plain. This region, known as the Po Valley, features a gentle topography with minimal elevation changes. The terrain is primarily composed of alluvial deposits, resulting in fertile soils that have been extensively cultivated for agriculture. As you move away from Annone Veneto, the landscape gradually transitions. To the north, the terrain begins to rise slightly as it approaches the foothills of the Alps. This area, known as the Prealps, features rolling hills and small valleys. To the east, the land remains relatively flat as it extends towards the Adriatic Sea, with numerous rivers and canals crisscrossing the countryside.
Potential for Solar PV Installation
When considering areas suitable for large-scale solar photovoltaic (PV) installations near Annone Veneto, several factors come into play. The flat, open spaces of the Venetian Plain offer promising locations for solar farms. These areas benefit from minimal shading and easy access for construction and maintenance. Particularly suitable regions might include: 1. Agricultural land to the south and southeast of Annone Veneto, where vast open fields provide ample space for solar panel arrays. However, care must be taken to balance energy production with preserving valuable farmland. 2. Former industrial sites or brownfields in the wider region, which could be repurposed for solar energy production. These areas often have existing infrastructure that can be adapted for solar installations. 3. The slightly elevated areas to the north, approaching the Prealps, may offer good solar exposure and could be suitable for solar farms, especially on south-facing slopes. It's important to note that while the topography is favorable, other factors such as local regulations, grid connectivity, and environmental considerations would need to be carefully evaluated before establishing any large-scale solar PV projects in the region. Additionally, the area's high agricultural value may pose challenges in terms of land use competition between farming and energy production.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.
