Solar PV Analysis of Tullinge, Sweden
The location at Tullinge, Stockholm County, Sweden has varying potential for generating energy through solar PV throughout the year. In simpler terms, this means that how much electricity you can get from solar panels changes with the seasons.
During summer, you could expect to generate 5.84 kWh of electricity per day for each kW of solar panels installed. This is a pretty good amount and makes summer an ideal time for solar energy production in Tullinge.
In autumn, this amount drops to 1.58 kWh/day per kW installed, which is significantly less than what can be produced in summer but still not too bad.
However, winter sees a big drop in potential output to just 0.57 kWh/day per kW installed - making it the least ideal season for solar energy production due to shorter daylight hours and typically overcast weather.
Spring sees an increase again with an expected output of 4.11kWh/day per kW installed - making it another good time for generating solar power.
If you're installing fixed panel installations at this location, tilting them at a 49-degree angle towards the south would help maximize your total year-round production from these panels.
Now let's talk about factors that might affect your ability to generate solar power here:
Sweden experiences long winters with short daylight hours and a lot of cloudy days - all of which can reduce how much sun reaches your panels and thereby decrease their output significantly during these months.
Also, snow accumulation on the panels during winter could further hinder their performance.
To counteract these issues:
- You could install adjustable tilt mounts that allow changing the panel angles according to season – steeper in winter (to shed off snow) and flatter in summer (to capture more sunlight).
- Regular cleaning/maintenance especially during winters would also ensure maximum efficiency by removing any accumulated snow or debris.
- Using higher efficiency or bifacial modules could also help capture more light under low-light conditions or when sunlight is reflecting off the snow.
Please note that these are general suggestions and it's best to consult with a local solar installation expert who can provide advice tailored to your specific situation.
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 174 locations across Sweden. 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 Tullinge
Seasonal solar PV output for Latitude: 59.2035, Longitude: 17.8808 (Tullinge, Sweden), 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 49° South in Tullinge, Sweden
To maximize your solar PV system's energy output in Tullinge, Sweden (Lat/Long 59.2035, 17.8808) throughout the year, you should tilt your panels at an angle of 49° 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 Tullinge, Sweden
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 Tullinge, Sweden. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 49° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 42° South in Summer | 61° South in Autumn | 71° South in Winter | 51° 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 Tullinge, Sweden
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 Tullinge, Sweden.
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 Tullinge, Sweden
Tullinge is located in the province of Södermanland, Sweden. The topography of Tullinge is characterized by a mix of flat and hilly terrain with forests, lakes, and residential areas. It has a typical Scandinavian landscape with lots of greenery.
For large-scale solar PV installations, flat open spaces are most suitable as they allow for maximum exposure to sunlight and ease of installation and maintenance. Given this requirement, the flatter regions around Tullinge would be most suitable for such installations.
However, it's important to note that Sweden's high latitude means it gets less sun than countries closer to the equator. This doesn't mean solar energy isn't viable in Sweden - indeed there are successful solar power projects in the country - but efficiency can be lower compared to more sun-drenched regions.
Furthermore, any large-scale solar project would need to consider factors beyond just topography including local climate conditions (like cloud cover), availability of infrastructure (like power grids), potential environmental impact (on local wildlife or ecosystems) and regulatory/political considerations (like zoning laws or renewable energy incentives). Therefore a comprehensive feasibility study should be conducted before deciding on specific locations for large-scale solar PV installations.
Sweden solar PV Stats as a country
Sweden ranks 36th in the world for cumulative solar PV capacity, with 1,577 total MW's of solar PV installed. This means that 0.70% of Sweden's total energy as a country comes from solar PV (that's 39th in the world). Each year Sweden is generating 152 Watts from solar PV per capita (Sweden ranks 34th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Sweden?
Yes, there are several incentives for businesses wanting to install solar energy in Sweden. The Swedish Energy Agency offers a number of grants and subsidies for businesses that want to invest in renewable energy sources such as solar power. Additionally, the government has implemented a feed-in tariff system which guarantees a fixed price for electricity generated from renewable sources such as solar. This helps to make investing in solar more attractive and financially viable for businesses.
