The location at Montagnola, Ticino, Switzerland is quite suitable for generating energy via solar photovoltaic (PV) systems throughout the year, but its productivity varies with each season. In simpler terms, a solar PV system installed here will produce different amounts of electricity depending on the time of year.
During summer, this location can generate an average of 6.75 kilowatt-hours (kWh) per day for every kilowatt (kW) of installed solar power. This makes summer the best time to generate solar energy in Montagnola due to longer daylight hours and higher sun intensity.
Spring is also a good season for solar production with an average output of 5.40 kWh/day per kW installed. Autumn sees a decrease in production to 3.12 kWh/day per kW because there are fewer daylight hours and less intense sunlight compared to summer and spring.
Winter has the lowest productivity with only 1.85 kWh/day per kW due to shorter days and often cloudier skies which limit sunlight exposure.
For optimum performance from your solar PV system in Montagnola throughout the year, it's recommended that your panels be tilted at an angle of 39 degrees facing South. This angle maximizes exposure to sunlight across all seasons leading to more total yearly electricity generation.
However, there could be some local factors that might affect your solar production here such as weather conditions or environmental elements like trees or buildings casting shadows on your panels reducing their exposure to sunlight especially during winter when the sun is lower in the sky.
To counter these potential issues you should ensure that your panels are not obstructed by any objects causing shadows and have them cleaned regularly as dust or snow can reduce their efficiency significantly if left unchecked.
Also consider using advanced technologies like tracking mounts which adjust panel positions based on sun's position or micro-inverters which optimize power output even when part of panel array is shaded.
Remember though that while mitigating factors can improve efficiency, the seasonal variations in sunlight are natural and unavoidable. The key is to plan your energy usage accordingly leveraging higher production periods like summer and spring.
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 245 locations across Switzerland. 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 Montagnola
Seasonal solar PV output for Latitude: 45.9739, Longitude: 8.9187 (Montagnola, Switzerland), 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 Montagnola, Switzerland
To maximize your solar PV system's energy output in Montagnola, Switzerland (Lat/Long 45.9739, 8.9187) 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 Montagnola, Switzerland
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 Montagnola, Switzerland. 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 |
|---|---|---|---|
| 30° South in Summer | 49° 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 Montagnola, Switzerland
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 Montagnola, Switzerland.
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 Montagnola, Switzerland
Montagnola is located in the Lugano district of Switzerland, which is characterized by a hilly and mountainous terrain. The area has several high peaks and valleys with dense vegetation. It is part of the Swiss Alps, so it's surrounded by scenic landscapes including forests, lakes and rivers.
As for solar PV installations, they are most effective in areas that have a high amount of sunlight throughout the year. Although Switzerland does not receive as much sun as some other countries due to its geographical location and climate, there are still possibilities for solar energy production.
Flat or gently sloping terrains would be most suitable for large-scale solar PV installations due to ease of installation and maintenance. Therefore, areas such as plains or valleys could be potential sites. However, considering Montagnola's hilly topography these might not be readily available.
Alternatively, south-facing slopes could also serve as good locations because they would receive more sunlight throughout the day compared to north-facing slopes.
Roofs of large buildings or infrastructure could also serve as potential sites for installing solar panels without requiring additional land space.
However, any decision on where to install should consider various factors such as local weather conditions (including cloud cover), availability of land/rooftop space, proximity to power grids etc., along with an assessment on environmental impact if it involves deforestation or altering natural habitats.
Lastly but importantly before undertaking any large scale project a detailed feasibility study must be conducted taking into account all these factors plus local laws & regulations related to renewable energy projects.
Switzerland solar PV Stats as a country
Switzerland ranks 25th in the world for cumulative solar PV capacity, with 3,449 total MW's of solar PV installed. This means that 4.70% of Switzerland's total energy as a country comes from solar PV (that's 16th in the world). Each year Switzerland is generating 399 Watts from solar PV per capita (Switzerland ranks 6th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Switzerland?
Yes, there are several incentives for businesses wanting to install solar energy in Switzerland. The Swiss Federal Office of Energy (SFOE) offers a range of financial support measures for businesses that want to invest in renewable energy sources such as solar power. These include grants, loans and tax deductions. Additionally, the Swiss government has set up a feed-in tariff system which guarantees a fixed price for electricity generated from renewable sources such as solar power. This helps to make investing in solar energy more attractive for businesses.
