Partille, Västra Götaland County, Sweden, situated at latitude 57.7401 and longitude 12.1037 in the Northern Temperate Zone, presents a location with significant seasonal variations for solar PV energy generation. The solar electricity output at this location shows pronounced differences throughout the year, with peak production occurring during summer months.

Solar energy generation in Partille follows a predictable seasonal pattern. During summer, panels can produce an impressive 5.63 kWh per day for each kilowatt of installed capacity. Spring offers the second-best performance with 4.16 kWh/day per kW. However, autumn sees a substantial drop to just 1.60 kWh/day per kW, while winter production falls to a minimal 0.68 kWh/day per kW.

For residents of Partille considering solar installation, it's worth noting that approximately 70% of the annual solar energy production occurs during spring and summer months. This makes the period from April through September the most productive for solar energy generation in this location.

Optimal Panel Installation

For fixed panel installations in Partille, Västra Götaland County, the ideal angle to maximize year-round production is 48 degrees tilted toward the South. This specific angle has been calculated to optimize energy capture throughout the year, accounting for the Earth's elliptical orbit and Partille's northern latitude.

Environmental Considerations

Several environmental factors can affect solar production in Partille. Snow accumulation during winter months presents the most significant challenge, potentially covering panels and drastically reducing output during already low-production periods. Installing panels at the recommended 48-degree tilt helps snow slide off more easily compared to flatter installations.

Cloud cover is another consideration in this region of Sweden, which experiences numerous overcast days throughout the year. While this cannot be prevented, using high-efficiency panels designed to perform better in diffuse light conditions can help mitigate production losses.

Tree coverage and building shadows should be carefully evaluated before installation, as the low sun angle, particularly in winter, creates longer shadows that may impact panel performance. A thorough site assessment to identify potential shading issues is essential for optimal placement.

Regular maintenance, including cleaning panels of debris, leaves, and bird droppings, becomes important to maintain efficiency. Automated cleaning systems or scheduled maintenance can help ensure panels operate at maximum capacity throughout the year.

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

Solar output per kW of installed solar PV by season in Partille

Seasonal solar PV output for Latitude: 57.7401, Longitude: 12.1037 (Partille, 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 48° South in Partille, Sweden

To maximize your solar PV system's energy output in Partille, Sweden (Lat/Long 57.7401, 12.1037) throughout the year, you should tilt your panels at an angle of 48° 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 Partille, 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 Partille, Sweden. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 48° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
41° South in Summer	59° South in Autumn	70° South in Winter	50° 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 Partille, 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 Partille, 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 Partille, Sweden

Partille, located in western Sweden near Gothenburg, sits within a landscape characterized by gentle hills, valleys, and waterways. The terrain around Partille features a mix of forested areas and open spaces, with elevations generally ranging between 20-100 meters above sea level. The municipality is situated in the valley of the Säveån river, which flows through the area before eventually reaching Gothenburg and the sea.

Topographical Features

The topography of Partille and its surroundings has been significantly shaped by glacial activity from the last ice age. This has resulted in a landscape with rolling hills, scattered lakes, and exposed bedrock in some areas. The underlying geology consists primarily of gneiss and granite, common throughout much of southern Sweden. To the north and east of Partille, the terrain becomes more elevated and forested, with several nature reserves featuring more rugged landscapes. South and west toward Gothenburg, the land gradually descends toward the coast, becoming more urbanized and developed.

Potential Areas for Solar PV Development

When considering areas around Partille suitable for large-scale solar photovoltaic installations, several factors must be evaluated beyond just topography, including land availability, grid connectivity, and environmental considerations. The relatively flat agricultural areas to the south and southeast of Partille present promising opportunities for solar development. These open spaces receive good solar exposure due to fewer natural obstructions and generally south-facing gentle slopes. The agricultural plains extending toward Lerum and Alingsås could accommodate larger installations while minimizing the need for extensive land clearing. Former industrial sites and brownfields in the broader Gothenburg region also offer potential for solar development. These areas often have existing grid connections and represent an opportunity to repurpose land with limited alternative uses. The hills to the north of Partille, while more challenging from an installation perspective, could potentially host smaller, strategically placed solar arrays on south-facing slopes. These elevated positions might benefit from reduced fog and shadow effects compared to valley locations. It's worth noting that Sweden's northern latitude means that optimal solar panel placement requires careful consideration of angle and orientation to maximize winter sun exposure when daylight is limited. Solar installations in this region typically require more land area per megawatt of capacity compared to more southerly locations. Any large-scale solar development would need to balance energy production potential with environmental considerations, as the forested areas surrounding Partille provide important ecosystem services and recreational value to the region.
