Solar PV Analysis of Cesena, Italy
The location in Cesena, Italy, situated at 44.1496° N, 12.2337° E, presents varying degrees of suitability for solar PV energy generation throughout the year. This Northern Temperate Zone location experiences significant seasonal fluctuations in solar energy production.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive daily output of 6.85 kWh per kW of installed solar capacity. Spring follows closely, yielding 5.46 kWh/day. However, the performance drops considerably during autumn and winter, with outputs of 3.23 kWh/day and 1.79 kWh/day, respectively.
These figures indicate that Cesena's location is particularly favorable for solar energy generation from late spring through early autumn. During this period, longer days and higher sun angles contribute to increased solar panel efficiency.
Optimal Panel Installation
To maximize year-round solar energy production at this location, fixed solar panels should be tilted at a 37-degree angle facing south. This optimal angle accounts for Cesena's latitude and the Earth's elliptical orbit, ensuring the best possible exposure to sunlight throughout the year.
Environmental Considerations
While Cesena's location is generally suitable for solar PV installations, there are some environmental factors to consider:
- Fog: The Po Valley region, where Cesena is located, is prone to fog, especially during autumn and winter. This can reduce solar panel efficiency.
- Snow: Although not frequent, occasional snowfall in winter can temporarily cover panels, reducing energy production.
To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding off and using anti-reflective coatings to improve performance in foggy conditions. Regular cleaning and maintenance can also help ensure optimal energy production throughout the year.
In conclusion, while Cesena's location presents challenges during the colder months, it offers excellent potential for solar energy generation, particularly from spring to early autumn. With proper installation and maintenance, solar PV systems can be a viable and efficient source of renewable energy in this Italian city.

Solar output per kW of installed solar PV by season in Cesena
Seasonal solar PV output for Latitude: 44.1496, Longitude: 12.2337 (Cesena, 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 Cesena, Italy
To maximize your solar PV system's energy output in Cesena, Italy (Lat/Long 44.1496, 12.2337) 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 Cesena, 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 Cesena, 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 Cesena, 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 Cesena, 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 Cesena, Italy
Cesena, located in the Emilia-Romagna region of northern Italy, sits in a diverse topographical area. The city itself is situated on relatively flat land in the Savio River valley, with an elevation of about 44 meters (144 feet) above sea level. As you move away from the city center, the landscape becomes more varied.
To the west and southwest of Cesena, the terrain gradually rises into the foothills of the Apennine Mountains. These hills become progressively steeper and more rugged as you move further inland. The eastern side of Cesena, in contrast, stretches towards the Adriatic coast, where the land remains predominantly flat and eventually meets the sea about 15 kilometers (9 miles) away.
The immediate surroundings of Cesena feature a mix of agricultural land, small woodlands, and scattered settlements. The Savio River, which runs through the city, has shaped the local topography over time, creating a gentle valley flanked by low hills.
When considering areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, several factors come into play. The ideal locations would be relatively flat, open areas with good sun exposure and minimal shading from nearby hills or mountains. Based on these criteria, the following areas near Cesena could be potentially suitable:
- The coastal plains to the east of Cesena: This flat, open terrain receives ample sunlight and has fewer natural obstacles that could cast shadows on solar panels.
- Agricultural areas in the Savio River valley: Many of these fields are already cleared and have good sun exposure, though care would need to be taken to balance solar development with agricultural needs.
- Gently sloping hillsides to the west, facing south or southeast: While not as ideal as flat land, these areas could still be suitable if they receive good sunlight throughout the day and are not too steep for installation.
It's important to note that any large-scale solar PV project would require detailed site-specific assessments, considering factors such as local regulations, grid connectivity, and environmental impact, in addition to topographical suitability.
