Solar PV Analysis of Zumikon, Switzerland
Zumikon, Zurich, Switzerland is a reasonable location for generating solar energy year-round with the highest output during summer and spring. In simpler terms, if you have a 1 kW solar panel system in Zumikon, Zurich, you could expect it to generate about 5.71 kilowatt-hours (kWh) of electricity per day in the summer, 4.85 kWh/day in the spring, 2.99 kWh/day in autumn and just 1.52 kWh/day in winter.
However, these values are not constant throughout each season because of weather variations - sunny days will produce more than cloudy or rainy ones. The best time to generate solar at this location would be during the summer and spring when sunlight is most abundant.
For fixed panel installations at this location, tilting your panels at an angle of about 40 degrees towards the south can help maximize total yearly production from your solar PV system.
As for local factors that could potentially affect solar production: Switzerland has a temperate climate with considerable cloud cover especially during winter months which can reduce sunlight availability hence lower energy generation from your panels. Additionally heavy snowfall may cover up your panels reducing their efficiency or even causing damage if not properly managed.
To counter these issues:
- Regular maintenance including cleaning off any accumulated dust or snow on the panels can help ensure they function optimally.
- Installing sensors that detect low light levels and adjust panel angles accordingly to maximize exposure to available sunlight.
- Use of high-quality durable panels capable of withstanding harsh weather conditions typical for this region.
Remember though that while these measures can improve performance they cannot eliminate all effects caused by seasonal changes and weather variations inherent to this location's climate zone.
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 Zumikon
Seasonal solar PV output for Latitude: 47.3372, Longitude: 8.6393 (Zumikon, 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 40° South in Zumikon, Switzerland
To maximize your solar PV system's energy output in Zumikon, Switzerland (Lat/Long 47.3372, 8.6393) throughout the year, you should tilt your panels at an angle of 40° 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 Zumikon, 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 Zumikon, Switzerland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 31° South in Summer | 50° South in Autumn | 61° South in Winter | 40° 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 Zumikon, 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 Zumikon, 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 Zumikon, Switzerland
Zumikon is located in the canton of Zurich, Switzerland. The topography around Zumikon is characterized by rolling hills and valleys with a mix of urban areas, forests, and farmland. It's situated at an elevation of approximately 600 meters above sea level.
The region experiences a temperate climate with ample sunlight during summer months but less so in winter due to cloud cover and shorter daylight hours. However, solar PV installations are still viable because even indirect sunlight can generate electricity.
In terms of specific locations for large-scale solar PV installations:
1. Open fields or farmlands: These areas often have fewer obstructions (like tall buildings or trees) that could block sunlight.
2. Rooftops: Large building rooftops in the urban parts of Zumikon could be suitable for smaller scale solar PV systems.
3. South-facing slopes: In this part of the hemisphere, south-facing slopes receive more direct sunlight throughout the year making them ideal places for solar panels.
4. Unused industrial lands: These could also be potential sites as they may have good sun exposure and would not require land-use changes from agricultural or protected natural spaces.
However, it's essential to note that any large-scale installation will need to consider factors such as local zoning regulations, environmental impacts (like effect on local wildlife), grid connectivity issues etc., before proceeding with development plans.
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.
