Solar PV Analysis of Finspang, Sweden
Finspang, Östergötland County, Sweden, located at latitude 58.7037 and longitude 15.7617, exhibits a varying degree of solar power potential across different seasons. During the summer months, each kilowatt of installed solar capacity can generate an average of 5.82 kilowatt-hours per day due to the extended daylight hours and direct sunlight exposure. As autumn approaches, this figure decreases to an average of 1.67 kilowatt-hours per day per kilowatt installed due to shorter days and less intense sunlight.
In winter, the daily energy yield further drops to approximately 0.67 kWh per kW owing to limited daylight hours and low sun angles that impede direct sunlight incidence on the panels. However, with the advent of spring and increasing daylight hours coupled with improved sun angles, it rises again to an average daily output of 4.36 kWh per kW.
For maximum efficiency in Finspang's geographical location for fixed panel installations without tracking systems in place; it is recommended that solar panels be tilted at an angle of roughly 49 degrees facing southwards for optimal annual energy production.
However, local weather conditions such as frequent cloud cover or strong winds could potentially hinder solar power generation by obstructing sunlight or causing physical damage respectively; hence these factors should be taken into account during installation planning phases.
To mitigate these challenges: ensuring robust structural support for panels against wind forces; employing advanced inverters capable of optimizing power output under variable light conditions; or considering hybrid systems incorporating wind turbines could be beneficial strategies for maximizing renewable energy production year-round in Finspang's context.
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 Finspang
Seasonal solar PV output for Latitude: 58.7037, Longitude: 15.7617 (Finspang, 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 Finspang, Sweden
To maximize your solar PV system's energy output in Finspang, Sweden (Lat/Long 58.7037, 15.7617) 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 Finspang, 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 Finspang, 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 | 60° 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 Finspang, 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 Finspang, 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 Finspang, Sweden
The topography around Finspang, Sweden is mostly flat with some low hills. Areas nearby that would be most suited to large-scale solar PV installations include open fields or areas with a high concentration of rooftops. The flat terrain and long summer days make this region ideal for solar energy production.
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.
