Solar PV Analysis of Saltsjoe-Boo, Sweden
The location at Saltsjoe-Boo, Stockholm County, Sweden, is not the most ideal for year-round energy generation through solar PV due to its position in the Northern Temperate Zone. However, it still has potential for solar energy production during certain times of the year.
In Summer and Spring, this location can generate a good amount of solar power with 6.18kWh/day and 4.26kWh/day per kW of installed solar respectively. These are the best seasons for generating solar energy here because of longer daylight hours and more direct sunlight.
On the other hand, Autumn and Winter have significantly lower energy output with only 1.54kWh/day and 0.51kWh/day per kW respectively due to shorter daylight hours and less direct sunlight.
For a fixed panel installation at this location, tilting panels at an angle of 49 degrees South is recommended to maximize total year-round production from solar PV.
As far as local factors that might impede on solar production go, Sweden's long winters could be a significant factor as they result in fewer hours of sunlight which reduces overall power generation from photovoltaic systems (solar panels). Additionally, snow cover on panels can also decrease their efficiency.
To counter these challenges:
1) Regular maintenance such as snow removal during winter months would be necessary to keep the panels clear.
2) Using tracking mounts that follow the sun's path across the sky could help increase efficiency.
3) Installing additional or larger capacity batteries could help store excess power generated during sunnier months for use during darker periods.
4) Finally, using high-efficiency panels designed to perform well even under less than ideal light conditions could also improve overall performance.
Remember though that while these measures can improve performance under challenging conditions they also add cost so it’s important to consider whether those additional costs make sense given your specific situation before deciding on them.
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 Saltsjoe-Boo
Seasonal solar PV output for Latitude: 59.3141, Longitude: 18.2517 (Saltsjoe-Boo, 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 Saltsjoe-Boo, Sweden
To maximize your solar PV system's energy output in Saltsjoe-Boo, Sweden (Lat/Long 59.3141, 18.2517) 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 Saltsjoe-Boo, 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 Saltsjoe-Boo, 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 Saltsjoe-Boo, 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 Saltsjoe-Boo, 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 Saltsjoe-Boo, Sweden
Saltsjö-Boo is located in the eastern part of Sweden, near the coast. The topography of this region is characterized by a mix of flat and hilly terrains with forests, lakes, and residential areas. It's a suburban area located on an archipelago with many islands.
The region has a temperate climate with relatively mild but cloudy winters and warm summers. It's worth noting that Sweden doesn't have as much sunlight compared to other countries due to its high latitude; however, solar power is still viable here.
For large-scale solar PV installations, flat open areas would be most suitable as they provide ample space for installing solar panels. Areas that are clear from obstructions like tall buildings or trees that could block sunlight are also ideal.
Potential locations could include:
1. Unused land spaces within the suburban area.
2. Rooftops of large buildings such as warehouses or malls.
3. Brownfield sites - these are previously developed lands that may be potentially contaminated but can be cleaned up for use.
4. Floating solar PV systems on bodies of water like lakes or reservoirs could also be considered.
However, it's important to conduct a detailed site analysis including aspects such as local weather patterns, soil condition (for ground-mounted systems), potential shading issues etc., before deciding on the exact location for installation.
In terms of grid connection and accessibility; locations closer to existing infrastructure would generally be more favorable unless budget allows for necessary upgrades or extensions to existing grid networks.
Keep in mind that public acceptance and environmental impact assessments will play crucial roles in determining suitable sites for large-scale solar developments too.
Lastly, while it’s technically feasible to install large scale PV in this region despite less optimal sun conditions compared to sunnier parts of world; economic feasibility will depend heavily on factors like local electricity prices, available incentives/subsidies for renewable energy etc., which should also be thoroughly evaluated during planning stages.
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.
