Lavagno, Veneto, Italy, situated at latitude 45.4439 and longitude 11.1307 in the Northern Temperate Zone, offers varying potential for solar energy production throughout the year. This location experiences significant seasonal fluctuations in solar PV output that prospective solar adopters should consider.

Seasonal Solar Production

Solar panels in Lavagno produce their highest output during summer months, generating approximately 6.83kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 5.28kWh/day per kW installed. Production drops considerably during autumn to 3.14kWh/day, while winter sees the lowest generation at just 1.77kWh/day per kW installed.

This seasonal pattern creates a production ratio of nearly 4:1 between summer and winter months, indicating that Lavagno residents would generate approximately four times more solar energy in summer than during the winter season.

Optimal Installation Angle

For fixed solar panel installations in Lavagno, Veneto, the ideal tilt angle to maximize year-round energy production is 39 degrees facing South. This specific angle has been calculated to optimize annual solar capture by accounting for the sun's changing position throughout the year and weighting the angle based on daily PV potential.

Environmental and Weather Considerations

Several environmental factors could impact solar production in Lavagno. Winter fog and low cloud cover in the Po Valley region, where Lavagno is located, can significantly reduce solar radiation during the already low-producing winter months. Additionally, occasional hail storms in summer months pose a physical risk to panels.

Snow accumulation in winter, though not typically heavy or long-lasting in this region, can temporarily cover panels and reduce output. Dust and pollen from agricultural activities in the surrounding areas may also gradually decrease panel efficiency if not addressed.

Preventative Measures

To maximize production despite these challenges, consider these preventative measures:

• Install panels with anti-reflective coatings and tempered glass to withstand potential hail impacts
• Implement a regular cleaning schedule, particularly after pollen seasons in spring
• Consider a slight increase in tilt angle (2-3 degrees above optimal) to facilitate snow sliding off panels
• Use microinverters or power optimizers to minimize production losses when parts of the array are shaded
• Install automated monitoring systems to quickly identify performance issues

While Lavagno offers good overall solar potential, the significant seasonal variation means that grid connection remains important for reliable year-round electricity, as winter production falls to approximately one-quarter of summer output levels.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 39° South in Lavagno, Italy

To maximize your solar PV system's energy output in Lavagno, Italy (Lat/Long 45.4439, 11.1307) 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 Lavagno, 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 Lavagno, 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	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 Lavagno, 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 Lavagno, 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 Lavagno, Italy

Lavagno, Italy is situated in the Veneto region, approximately 10 kilometers east of Verona. The topography around Lavagno is characterized by a transition between the Venetian Plain and the foothills of the Lessini Mountains, creating a varied landscape that combines flatlands, gentle hills, and more pronounced elevations. The immediate area around Lavagno features undulating terrain with elevations ranging from approximately 40 meters above sea level in the southern portions to around 300 meters in the northern parts. This gradual rise in elevation creates a series of rolling hills that define much of the local landscape. The southern and southwestern areas of Lavagno extend into the broader Po Valley, presenting relatively flat terrain that gradually slopes toward the Adige River.

Surrounding Topographical Features

To the north of Lavagno, the landscape becomes more pronounced as it transitions into the Lessini Mountains, a subgroup of the pre-Alps. These mountains feature steeper slopes and more significant elevation changes, with peaks reaching over 1,000 meters in the broader region. The eastern portion of the territory includes the Val d'Illasi, a valley that runs north-south and contains its own microtopography of valley floor and sloping sides. The western side of Lavagno borders the eastern outskirts of Verona, where the terrain is generally flatter as it forms part of the Venetian Plain. Small streams and drainage channels cross this landscape, including the Progno di Mezzane, which flows through the area.

Potential Areas for Solar PV Development

When considering large-scale solar photovoltaic development, several areas near Lavagno present favorable conditions based on topographical factors: The southern flatlands extending toward San Martino Buon Albergo offer the most immediate potential for large-scale solar installations. This area features relatively flat terrain with minimal shadowing from geographical features, making it ideal for contiguous solar arrays. The gradual south-facing slopes found in the transitional areas between the plain and the first hills could provide enhanced solar exposure throughout the day. Some of the gently rolling hills to the east and northeast of Lavagno, particularly those with southern exposures, might also be suitable for solar development. These areas benefit from reduced risk of morning and evening shadowing that can affect flat terrain near mountain ranges. However, steeper sections would require more complex installation techniques and might reduce overall efficiency. The broader agricultural plains to the southwest, extending toward Caldiero and Zevio, represent another potential area for large-scale solar development. These expanses of relatively flat land offer the possibility for significant installations, though agricultural use currently predominates in many of these areas. Areas to avoid would include the more pronounced hills and mountainous regions to the north, where shadowing effects, difficult terrain, and higher elevations make installation more challenging and potentially less productive. Similarly, areas immediately adjacent to waterways or in flood-prone zones would present additional complications for solar infrastructure. The ideal locations combine accessibility, minimal shadowing from surrounding topography, stable ground conditions, and appropriate orientation to maximize solar exposure throughout the year. The transitional zones between the Venetian Plain and the first rises of the pre-Alpine foothills offer this balance of characteristics in the vicinity of Lavagno.
