Rimini, Italy, situated at 44.0545° N latitude and 12.5686° E longitude, offers a varied solar energy potential throughout the year. Located in the Northern Temperate Zone, this coastal city experiences distinct seasonal changes that significantly impact solar PV generation.

Seasonal Solar Performance

Solar energy production in Rimini fluctuates considerably across seasons. Summer stands out as the most productive period, with an impressive 6.85 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 5.46 kWh/day. Autumn sees a notable decrease to 3.23 kWh/day, while winter experiences the lowest output at 1.79 kWh/day.

The substantial variation between summer and winter highlights the importance of proper system sizing to ensure adequate year-round energy production. While summer months offer excellent solar potential, the significant drop in winter output may necessitate alternative energy sources or energy storage solutions for consistent power supply.

Optimal Panel Installation

To maximize year-round solar energy production in Rimini, fixed solar panels should be tilted at an angle of 37 degrees facing south. This optimal angle takes into account the city's latitude and seasonal sun positions, balancing energy capture across all seasons.

Environmental Considerations

Rimini's coastal location presents some challenges for solar PV installations. The proximity to the Adriatic Sea can lead to increased humidity and salt spray, potentially affecting solar panel efficiency and longevity. To mitigate these issues, installers should consider using corrosion-resistant materials and applying protective coatings to the panels and mounting hardware.

Additionally, the region may experience occasional fog, particularly in autumn and winter, which can temporarily reduce solar output. While this is not a major impediment, it underscores the importance of accurate weather data in system design and output predictions.

Preventative Measures

To enhance solar production and system durability in Rimini's coastal environment, consider the following measures:

• Use marine-grade materials for all components exposed to the elements
• Implement a regular cleaning schedule to remove salt deposits and other debris
• Install micro-inverters or power optimizers to minimize the impact of partial shading from fog or cloud cover

By addressing these local factors and implementing appropriate preventative measures, solar PV systems in Rimini can achieve optimal performance and longevity, capitalizing on the location's favorable solar potential, especially during the spring and summer months.

Solar output per kW of installed solar PV by season in Rimini

Seasonal solar PV output for Latitude: 44.0545, Longitude: 12.5686 (Rimini, 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 37° South in Rimini, Italy

To maximize your solar PV system's energy output in Rimini, Italy (Lat/Long 44.0545, 12.5686) throughout the year, you should tilt your panels at an angle of 37° 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 Rimini, 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 Rimini, Italy. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
28° South in Summer	47° South in Autumn	58° South in Winter	37° 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 Rimini, 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 Rimini, 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 Rimini, Italy

Rimini, a coastal city in Italy's Emilia-Romagna region, is situated on the Adriatic Sea. The topography around Rimini is characterized by a diverse landscape that transitions from flat coastal plains to rolling hills as you move inland. The immediate area surrounding Rimini is predominantly flat, with sandy beaches stretching along the coastline. This flat terrain extends for several kilometers inland, creating a wide coastal plain. As you move away from the coast, the landscape gradually begins to undulate, with gentle hills becoming more prominent.

Coastal Plain

The coastal plain around Rimini is a result of centuries of sediment deposition from rivers and coastal processes. This area is largely urbanized, with the city of Rimini and its surrounding towns occupying much of the flat land near the coast. The plain is crisscrossed by several small rivers and streams that flow from the hills to the Adriatic Sea.

Foothills and Valleys

As you move further inland, the terrain becomes more varied. The foothills of the Apennine Mountains begin to appear, creating a landscape of rolling hills and shallow valleys. These hills are generally not very high, typically ranging from 100 to 300 meters above sea level. The valleys between these hills are often cultivated, with vineyards and orchards taking advantage of the fertile soil.

Monte Titano

To the southwest of Rimini lies Monte Titano, the highest point in the nearby microstate of San Marino. This mountain, standing at 749 meters (2,457 feet) above sea level, is a prominent feature in the landscape and can be seen from many parts of Rimini on clear days.

Potential for Solar PV

When considering areas suitable for large-scale solar PV installations near Rimini, several factors come into play. The coastal plain, while flat and easily accessible, is heavily urbanized and may not have large open areas available for solar farms. However, the gently rolling hills inland from Rimini offer promising potential for solar energy development. The hills to the southwest and west of Rimini, extending towards San Marino, could be particularly well-suited for solar PV installations. These areas benefit from: 1. Elevated terrain that receives good sun exposure throughout the day 2. Less urbanization, meaning more open land potentially available for development 3. Proximity to existing infrastructure and the power grid It's important to note that any large-scale solar development would need to balance energy production goals with preserving the region's agricultural heritage and natural beauty. Careful site selection and environmental impact assessments would be crucial to ensure that solar farms can coexist harmoniously with the local landscape and ecosystems.
