Solar Energy Potential in Johanneshov, Stockholm County, Sweden

Johanneshov, Stockholm County, located in Stockholm, Sweden, presents a unique case for solar energy generation. Situated at latitude 59.3333 and longitude 18.05 in the Northern Temperate Zone, this location experiences significant seasonal variations in solar energy potential. The summer months offer the most promising conditions for solar energy production, with an average daily output of 6.10 kWh per kW of installed solar capacity. This period, typically from June to August, provides long daylight hours and more direct sunlight, making it ideal for solar energy generation. Spring follows as the second-most productive season, yielding an average of 4.18 kWh per day for each kW of installed capacity. This season, generally spanning from March to May, sees increasing daylight hours and improving solar angles.

Challenges in Autumn and Winter

Autumn and winter present significant challenges for solar energy production in Johanneshov. Autumn months (September to November) see a dramatic drop in output to 1.48 kWh per day, while winter (December to February) experiences the lowest production at just 0.48 kWh per day per kW installed. These stark seasonal differences highlight the need for careful planning and potentially supplementary energy sources during the colder, darker months.

Optimal Panel Installation

To maximize year-round solar energy production, fixed solar panels in Johanneshov should be installed at a tilt angle of 49 degrees facing south. This angle optimizes the panels' exposure to available sunlight throughout the year, balancing the low winter sun with the higher summer sun.

Environmental and Weather Considerations

Several factors can impede solar production in Johanneshov: 1. Snow accumulation in winter 2. Reduced daylight hours during winter months 3. Potential cloud cover, especially in autumn and winter To mitigate these issues, consider the following measures:

• Install panels at a steeper angle to encourage snow sliding off
• Use high-efficiency panels to maximize production during limited daylight
• Implement regular cleaning and maintenance, especially after snowfall
• Consider a hybrid system with wind energy to complement solar during less productive months

While Johanneshov faces challenges for year-round solar energy production, careful planning and appropriate technology can still make solar a viable part of the local energy mix, particularly when combined with other renewable sources.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 49° South in Johanneshov, Sweden

To maximize your solar PV system's energy output in Johanneshov, Sweden (Lat/Long 59.3333, 18.05) 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 Johanneshov, 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 Johanneshov, 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 Johanneshov, 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 Johanneshov, Sweden.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Johanneshov, Sweden

Johanneshov, located in Stockholm County, Sweden, is situated in an area characterized by a mix of urban and natural landscapes. The topography around Johanneshov is generally flat to gently rolling, with some low hills and small valleys interspersed throughout the region. The area is part of the Stockholm archipelago, which means it is influenced by both land and water features. To the north and west of Johanneshov, the terrain becomes more urbanized as it approaches central Stockholm. This area is dominated by buildings, roads, and other urban infrastructure, with fewer natural features. However, there are still pockets of green spaces and parks scattered throughout the city. To the south and east, the landscape becomes more varied and open. Here, you'll find a combination of forested areas, agricultural fields, and small bodies of water. The terrain in these directions tends to be slightly more undulating, with occasional rocky outcrops typical of the Swedish landscape.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. Ideally, solar farms require large, open spaces with minimal shading and good exposure to sunlight. Given these criteria, the areas to the south and east of Johanneshov show more promise for solar development. The agricultural lands and open fields in these directions provide the necessary space for large-scale installations. These areas are generally flatter and have fewer obstructions that could cast shadows on solar panels. Additionally, being further from the dense urban center means there is less competition for land use. However, it's important to note that Sweden's northern latitude means that solar energy production may not be as efficient as in more southern countries. The long summer days can be advantageous, but the short winter days and potential snow cover present challenges. Therefore, any large-scale solar PV project in this region would need to carefully consider these factors and implement appropriate technologies to maximize energy production throughout the year. While the immediate vicinity of Johanneshov may not be ideal for expansive solar farms due to urban development, the surrounding rural areas within Stockholm County could offer suitable locations for such projects. These installations would need to balance energy production goals with environmental considerations and local land use regulations.
