Solar PV Analysis of Reggio Emilia, Italy
The location at Reggio Emilia, Italy is reasonably suitable for generating energy via solar PV year-round, but it's not ideal. The best time to generate solar power would be during the summer when you can expect an output of 7.12kWh per day for each kW of installed solar. This is because the sun shines longer and more directly onto the panels during this season.
Spring also offers a good amount of energy generation with 5.46kWh/day per kW of installed solar due to increasing daylight hours and better weather conditions compared to winter or autumn.
Autumn sees a significant drop in potential output down to 3.29kWh/day per kW as days become shorter and there's less sunlight available.
Winter has the least productivity with only 1.85kWh/day per kW due to short days and often cloudy or rainy weather which obstructs sunlight from reaching the panels efficiently.
For fixed panel installations at this location, tilting panels at an angle of 38 degrees facing south will maximise total year-round production from solar PV by aligning them more directly towards the sun’s path across the sky throughout different seasons.
As for environmental factors that could potentially impede solar production in Reggio Emilia, these may include foggy or overcast conditions common in Northern Italy especially during winter months which reduce sunlight exposure on panels significantly affecting their performance.
To help ensure greater energy production despite these factors, one preventative measure would be regular cleaning and maintenance of your solar panels as dust, dirt or snow can cover them reducing their efficiency drastically. Additionally, using advanced technology like tracking systems that move your panels following sun’s position throughout the day could also increase overall electricity output significantly by ensuring maximum exposure regardless of seasonal variations in sun’s path.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 338 locations across Italy. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Reggio Emilia
Seasonal solar PV output for Latitude: 44.7022, Longitude: 10.6307 (Reggio Emilia, 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 Reggio Emilia, Italy
To maximize your solar PV system's energy output in Reggio Emilia, Italy (Lat/Long 44.7022, 10.6307) 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 Reggio Emilia, 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 Reggio Emilia, 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 |
|---|---|---|---|
| 28° South in Summer | 48° South in Autumn | 59° 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 Reggio Emilia, 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 Reggio Emilia, 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 Reggio Emilia, Italy
Reggio Emilia is located in the northern part of Italy, within the region of Emilia-Romagna. The city sits on the plain of the River Po, surrounded by a landscape that gradually transitions from flat plains to gentle hills and then to mountains as you move south towards the Apennines.
The area around Reggio Emilia presents a mixed topography, with flat areas ideal for agriculture and hilly regions that are more suitable for vineyards or forestation. The climate is typically Mediterranean with hot summers and mild winters which makes it potentially suitable for solar PV installations.
For large-scale solar photovoltaic (PV) systems, flat areas are usually preferred because they allow easier installation and maintenance, reduce shading issues between panels and often have better sun exposure. Therefore, agricultural lands or industrial zones near Reggio Emilia could be potential sites for such systems.
However, there are several factors beyond just topography that must be considered when deciding where to install large-scale solar PV systems. These include local climate conditions (amount of sunlight), land use restrictions, proximity to power grids for electricity transmission as well as environmental impacts among others.
Therefore a detailed site-specific analysis would be required to determine which specific areas nearby would be most suited for large scale solar PV installations.
Italy solar PV Stats as a country
Italy ranks 6th in the world for cumulative solar PV capacity, with 22,698 total MW's of solar PV installed. This means that 8.30% of Italy's total energy as a country comes from solar PV (that's 8th in the world). Each year Italy is generating 381 Watts from solar PV per capita (Italy ranks 7th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Italy?
Yes, there are several incentives for businesses wanting to install solar energy in Italy. The Italian government offers a range of financial incentives and tax credits for businesses that install solar energy systems. These include the Conto Energia scheme, which provides feed-in tariffs for electricity generated from renewable sources; the Superbonus 110%, which allows businesses to deduct up to 110% of their investment in renewable energy systems from their taxes; and the Ecobonus 65%, which provides a 65% tax deduction on investments in renewable energy systems. Additionally, businesses may be eligible for grants or loans from regional governments or other organizations.
