Edolo, Italy, located at coordinates 46.1754, 10.3339 in the Northern Temperate Zone, demonstrates varying potential for solar energy generation throughout the year. The location experiences significant seasonal fluctuations in solar electricity production that affect its overall suitability for photovoltaic (PV) systems.

Seasonal Solar Production

Solar energy generation in Edolo shows marked seasonal variations. During summer, panels can produce an impressive 5.90kWh per day for each kilowatt of installed capacity. Spring follows closely with 5.20kWh/day per kW. However, production drops considerably in autumn to 3.20kWh/day, and reaches its lowest point in winter with just 2.06kWh/day per kW of installed capacity.

These figures reveal that Edolo's solar potential is heavily concentrated in the warmer months, with summer and spring accounting for the majority of annual production. The substantial decrease during autumn and particularly winter indicates that supplementary energy sources would be beneficial during colder months.

Optimal Panel Installation

For fixed solar panel installations in Edolo, the ideal tilt angle to maximize year-round energy production is 40 degrees facing South. This angle optimizes the capture of available sunlight across seasons, balancing between the higher summer sun and lower winter sun positions.

Environmental Considerations

Several environmental factors may impact solar production in Edolo:

• Mountain shadowing effects, as Edolo is located in the Alpine region of Lombardy, which can reduce daily sunlight hours in certain locations
• Winter snowfall, which can cover panels and reduce efficiency unless regularly cleared
• Potential fog and cloud cover in valley areas, particularly during autumn and winter months

Preventative Measures

To maximize solar energy production in Edolo despite these challenges, several preventative measures can be implemented:

Installing panels at the recommended 40-degree tilt helps shed snow more effectively than flatter installations. Selecting locations with minimal shadowing from surrounding mountains or structures is crucial for consistent production. Anti-reflective and self-cleaning panel coatings can improve performance in variable weather conditions.

For properties with suitable exposure, dual-axis tracking systems could significantly increase energy capture, especially during the productive summer months, though at higher installation and maintenance costs than fixed systems.

Overall, Edolo presents good potential for solar energy generation, particularly from spring through autumn, though winter production remains limited. Supplementary energy sources would be recommended for the colder months when solar generation drops to approximately one-third of summer levels.

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 Edolo

Seasonal solar PV output for Latitude: 46.1754, Longitude: 10.3339 (Edolo, 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 40° South in Edolo, Italy

To maximize your solar PV system's energy output in Edolo, Italy (Lat/Long 46.1754, 10.3339) throughout the year, you should tilt your panels at an angle of 40° 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 Edolo, 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 Edolo, Italy. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
30° South in Summer	50° South in Autumn	60° South in Winter	39° 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 Edolo, 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 Edolo, 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 Edolo, Italy

Edolo is nestled in the heart of the Italian Alps, specifically in the upper Valcamonica valley in the province of Brescia, Lombardy region. The topography surrounding this Alpine town is characterized by steep mountain slopes, deep valleys, and high-elevation terrain typical of the central Alps. The town itself sits at an elevation of approximately 700 meters (2,300 feet) above sea level, positioned at the confluence of the Oglio River and its tributary, the Malonno. Surrounding Edolo are impressive mountain peaks that rise to over 3,000 meters (9,800 feet), creating a dramatic alpine landscape. The most prominent mountains nearby include the Adamello massif to the southwest and the Ortler Alps to the northeast.

Valley Configuration

Edolo is situated in a relatively narrow section of the Valcamonica valley, with steep mountain slopes rising rapidly from the valley floor. The valley generally runs in a north-south direction here, with Edolo positioned at a significant junction where the valley splits - one branch continuing northward toward the Tonale Pass and another heading northeast toward the Aprica Pass. The valley floor near Edolo contains the main settlement areas and transportation routes, including the SS42 highway. As is typical of Alpine valleys, the lower slopes are often forested, while higher elevations transition to alpine meadows and eventually bare rock near the summits.

Potential for Solar PV Development

For large-scale solar photovoltaic (PV) installations near Edolo, several factors must be considered given the mountainous topography. The most suitable areas would likely include: South-facing slopes at moderate elevations provide the best natural orientation for solar collection in the Northern Hemisphere. Several of the mountain slopes that face south or southwest in the vicinity of Edolo would receive substantial direct sunlight, particularly those at elevations between 800-1,500 meters where they rise above potential valley fog or shadow effects. The broader, more open sections of the valley floor, particularly to the south of Edolo where the Valcamonica widens somewhat, might offer flat terrain suitable for larger installations. However, these areas may face competing land uses from agriculture or development.

Topographical Challenges

The mountainous topography presents several challenges for large-scale solar development. The steep slopes that characterize much of the area around Edolo can complicate construction and maintenance of solar facilities. Additionally, the high mountains surrounding the valley cast significant shadows, particularly during winter months when the sun's path is lower in the sky. Valley orientation affects sunlight exposure significantly. While the Valcamonica's general north-south orientation is favorable in principle, the high mountains on either side can limit the effective sunlight window, especially during early morning and late afternoon.

Most Promising Areas

The most promising areas for large-scale solar PV development near Edolo would likely be: The broader sections of valley floor south of Edolo toward Cedegolo, where the valley widens and offers more level terrain with fewer shadowing effects from surrounding mountains. South-facing terraced slopes that have already been modified for human use, such as former agricultural terraces or managed forest areas, particularly on the western side of the valley. The elevated plateau areas near the Aprica Pass to the northeast, which offer relatively flat terrain at higher elevations with good exposure to sunlight. Areas near existing infrastructure, including along the SS42 highway corridor where grid connections might be more readily available, though careful consideration would need to be given to visual impact in this scenic Alpine region.
