Solar PV Analysis of Segrate, Italy
The location at Segrate, Lombardy, Italy is fairly good for generating energy via solar PV panels year-round, although it's not perfect. The amount of electricity you can produce will change depending on the season.
In the summer, you can expect to generate about 6.75kWh of electricity per day for each kW of solar power installed. This makes summer an ideal time for solar energy production in this location due to long daylight hours and direct sunlight.
During autumn, the output drops to around 3.12kWh/day per kW installed because there are fewer daylight hours and the sun is lower in the sky.
Winter sees a further decrease with only about 1.85kWh/day per kW installed being produced due to shorter days and less intense sunlight.
Spring sees an increase again with approximately 5.40kWh/day per kW installed as days get longer and sunlight becomes more intense again.
For a fixed panel installation at this location, tilting your panels at an angle of 39 degrees towards South would maximize your total year-round solar PV production as it aligns well with the path of sun across all seasons.
As far as local factors that could impede solar production go, Northern Italy does experience some foggy conditions especially during winter months which could reduce sunlight reaching your panels hence lowering their productivity; also tall buildings or trees might block direct sunlight if they're close by your installation site.
To ensure greater energy production despite these potential obstacles:
1) Choose a spot for your panels that has clear line-of-sight to the sky.
2) Regularly clean and maintain your panels so they work efficiently even when light conditions aren't optimal.
3) If possible, consider installing tracking systems that adjust panel angles throughout the day/year - this can help compensate when sun isn't directly overhead.
4) Install additional capacity (more/bigger panels), if space allows it - this way even on less sunny days you'll still generate a decent amount of power.
In general, while Segrate isn't the absolute best location for solar PV in the world (like deserts near equator), it's still pretty good and with proper setup and maintenance you can expect to generate a significant amount of electricity from solar panels installed there.
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 278 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 Segrate
Seasonal solar PV output for Latitude: 45.4931, Longitude: 9.3009 (Segrate, 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 39° South in Segrate, Italy
To maximize your solar PV system's energy output in Segrate, Italy (Lat/Long 45.4931, 9.3009) 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 Segrate, 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 Segrate, 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 | 60° 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 Segrate, 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 Segrate, 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 Segrate, Italy
Segrate is a town located in the Lombardy region of northern Italy. The topography around Segrate is largely flat, with some gentle rolling hills and valleys. It's characterized by its urban landscape as it's part of the larger metropolitan city of Milan.
The Lombardy region has a mixed climate, with warm summers and cold, foggy winters which might affect solar PV efficiency during certain periods. However, considering the relatively flat terrain around Segrate, there are likely many suitable areas for large-scale solar PV installations.
Potential sites could include:
1) Unused or underutilized industrial land: Given its proximity to Milan, there may be available commercial or industrial spaces that could accommodate large-scale solar installations.
2) Rooftops: Large buildings such as warehouses or factories often have extensive rooftop spaces that can be used for solar panels.
3) Agricultural lands: If local regulations permit, parts of agricultural lands not suitable for cultivation could also be considered for setting up solar farms without compromising food production.
However, conducting an on-site survey would provide more accurate information regarding shading issues from nearby structures or vegetation and other factors like local weather conditions that can influence the effectiveness of a potential PV installation.
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.
