Due Carrare, Veneto, Italy, located at 45.2929° N, 11.8243° E, presents a varied landscape for solar energy production throughout the year. This Northern Temperate Zone location experiences significant seasonal fluctuations in solar energy potential, which impacts the efficiency of photovoltaic (PV) systems.

Seasonal Solar Performance

The solar energy output in Due Carrare varies considerably across the four seasons. Summer stands out as the most productive period, with an impressive 6.87 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second-best season, generating 5.34 kWh/day/kW. Autumn sees a significant drop to 3.20 kWh/day/kW, while winter experiences the lowest output at 1.83 kWh/day/kW.

These figures indicate that Due Carrare is most ideal for solar energy production during the spring and summer months, from approximately March through August. During this period, longer days and higher sun angles contribute to increased solar radiation reaching the panels.

Optimizing Panel Installation

To maximize year-round solar energy production in Due Carrare, Veneto, fixed solar panels should be installed at a tilt angle of 38 degrees facing south. This optimal angle takes into account the location's latitude and seasonal variations in sun position, ensuring the best possible energy capture throughout the year.

Environmental and Weather Considerations

While Due Carrare's location is generally favorable for solar energy production, there are some environmental factors to consider:

• Fog and haze: The Po Valley, where Due Carrare is situated, is known for occasional fog, especially in autumn and winter. This can temporarily reduce solar panel efficiency.
• Snow: Winter snowfall, though not excessive, can cover panels and reduce energy production.

To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off and use self-cleaning panels to reduce the impact of fog and haze. Regular maintenance and cleaning can also help ensure optimal performance.

In conclusion, while Due Carrare experiences significant seasonal variations in solar energy potential, it remains a viable location for solar PV installations. With proper planning and optimization, solar energy can be effectively harnessed, particularly during the productive spring and summer months.

Solar output per kW of installed solar PV by season in Due Carrare

Seasonal solar PV output for Latitude: 45.2929, Longitude: 11.8243 (Due Carrare, 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 38° South in Due Carrare, Italy

To maximize your solar PV system's energy output in Due Carrare, Italy (Lat/Long 45.2929, 11.8243) throughout the year, you should tilt your panels at an angle of 38° 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 Due Carrare, 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 Due Carrare, Italy. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° 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	59° 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 Due Carrare, 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 Due Carrare, Italy.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Due Carrare, Italy

The area surrounding Due Carrare, Italy, located at coordinates 45.2929 latitude and 11.8243 longitude, is characterized by a predominantly flat landscape typical of the Venetian Plain. This region, known as the Po Valley, is one of the largest and most important alluvial plains in Europe. The terrain around Due Carrare is mostly level, with very gentle slopes and minimal elevation changes. The topography of this area has been shaped over millennia by the action of rivers and streams, particularly the Adige and Bacchiglione rivers, which have deposited sediments and created a fertile plain. The land is crisscrossed by a network of smaller waterways, irrigation canals, and drainage ditches, which have been crucial for agriculture in the region. To the north and west of Due Carrare, the landscape remains consistently flat, extending towards the cities of Padua and Vicenza. However, as one moves south and southeast, the terrain begins to show some variation. The Euganean Hills, a group of volcanic formations, rise abruptly from the plain approximately 10-15 kilometers south of Due Carrare. These hills, while not particularly high (the tallest peak, Monte Venda, reaches only 601 meters), provide a stark contrast to the surrounding flatlands.

Suitability for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, the flat agricultural lands surrounding Due Carrare offer significant potential. These areas have several advantages for solar energy production: Firstly, the level terrain reduces the cost and complexity of site preparation for solar panel installation. The absence of significant slopes or uneven ground makes it easier to optimize panel orientation and maximize sun exposure throughout the day. Secondly, the open nature of the agricultural landscape means there are fewer obstructions that could cast shadows on solar panels, ensuring consistent energy production. The vast expanses of farmland provide ample space for large-scale installations without the need for extensive land clearing. The areas to the north and west of Due Carrare, extending towards Padua and Vicenza, are particularly well-suited for solar PV projects. These regions offer large, contiguous plots of land that could accommodate substantial solar farms. Additionally, the proximity to urban centers like Padua could be advantageous for grid connection and energy distribution. However, it's important to note that the use of productive agricultural land for solar installations may face regulatory and social challenges. Therefore, ideal locations might include marginal agricultural lands or areas already zoned for industrial use. While the Euganean Hills to the south provide some elevated terrain, their slopes and forested areas make them less suitable for large-scale solar projects. The hills' topography would complicate installation and potentially reduce overall efficiency due to varied sun exposure throughout the day. In conclusion, the flat, open areas surrounding Due Carrare offer promising conditions for large-scale solar PV development, with the most suitable locations likely being the level agricultural lands to the north and west of the town.
