Laholm, Halland County, Sweden, located at coordinates 56.5152, 13.0407, presents a moderately viable location for solar PV energy generation, with significant seasonal variations in output. This northern temperate zone location experiences dramatic differences between summer and winter solar production.

The energy generation potential varies substantially throughout the year. During summer months, solar panels can produce a respectable 5.59kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 4.21kWh/day per kW installed. However, autumn production drops significantly to just 1.67kWh/day, and winter performance plummets to a minimal 0.73kWh/day per kW of installed capacity.

Optimal Panel Installation

For fixed solar panel installations in Laholm, Halland County, the ideal tilt angle to maximize year-round energy production is 47 degrees facing South. This carefully calculated angle balances the seasonal variations in sun position to optimize overall annual energy harvest.

Seasonal Considerations

The substantial difference between summer and winter production (nearly 8 times more energy in summer) indicates that Laholm is primarily a warm-season solar location. The period from late spring through early autumn (approximately May through September) will generate the vast majority of annual solar energy, making these months ideal for solar production.

Environmental Challenges

Several environmental factors could impact solar production in Laholm. Snow accumulation during winter months can significantly reduce already low winter production if panels become covered. Installing panels at the steep 47-degree angle helps somewhat with snow shedding, but occasional manual clearing may be necessary.

Cloud cover is another consideration in this coastal Swedish region, which experiences considerable overcast days, particularly in late autumn and winter. This is already reflected in the seasonal production figures but emphasizes the importance of efficient inverter technology that performs well in diffuse light conditions.

Additionally, Laholm's northern location means potential dust and pollen accumulation during spring and summer can impact panel efficiency during the most productive months. Regular cleaning maintenance, possibly including automated cleaning systems, would help maintain optimal performance during these critical high-production periods.

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 Laholm

Seasonal solar PV output for Latitude: 56.5152, Longitude: 13.0407 (Laholm, 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 47° South in Laholm, Sweden

To maximize your solar PV system's energy output in Laholm, Sweden (Lat/Long 56.5152, 13.0407) throughout the year, you should tilt your panels at an angle of 47° 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 Laholm, 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 Laholm, Sweden. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 47° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
40° South in Summer	58° South in Autumn	69° South in Winter	48° 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 Laholm, 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 Laholm, 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 Laholm, Sweden

The terrain around Laholm, Sweden presents a diverse topographical landscape characteristic of southern Sweden's coastal regions. Situated in Halland County along the Kattegat coast, Laholm's surrounding area transitions from flat coastal plains in the west to gradually rising terrain moving eastward. The coastal zone features sandy beaches and dunes, while the immediate inland area consists primarily of relatively flat agricultural land and meadows. As one moves further inland from Laholm, the landscape begins to undulate with gentle hills and shallow valleys. The Lagan River, which flows through Laholm before emptying into the Kattegat, has carved a notable valley that influences the local topography. This river valley creates some variation in elevation throughout the region, though dramatic relief is not a defining characteristic of the area.

Elevation Patterns

The elevation around Laholm ranges from sea level along the coast to approximately 100-150 meters above sea level in the eastern parts of the municipality. This gradual increase in elevation creates a subtle but noticeable transition from the coastal plains to the more forested interior regions. The higher elevations are generally found to the northeast and east, where the terrain begins to merge with the southern Swedish highlands.

Land Cover and Vegetation

The land cover around Laholm varies considerably. The western coastal areas feature sandy soils with scattered vegetation, while the central parts of the region are dominated by agricultural fields and pastures. Moving eastward, the landscape becomes increasingly forested, with mixed coniferous and deciduous woodlands becoming more prevalent at higher elevations.

Solar PV Suitability

For large-scale solar photovoltaic installations, several areas around Laholm show particular promise. The relatively flat agricultural lands to the south and southeast of Laholm town offer ideal conditions for solar development. These areas benefit from minimal shadowing effects due to their open character and gentle topography. The agricultural plains also provide the necessary space for extensive installations while having existing access to transportation infrastructure. The slightly elevated areas to the east, while featuring more varied terrain, contain numerous plateaus and south-facing slopes that could be advantageous for solar collection. These locations might offer improved performance due to their elevated position and reduced morning fog compared to the coastal lowlands.

Topographical Considerations

From a purely topographical perspective, the most suitable zones for large-scale solar development would be: 1. The agricultural plains between Laholm and Båstad to the south, which offer extensive flat terrain with minimal obstruction. 2. The gently rolling farmlands east of the E6 highway, where large open fields provide ample space while maintaining good drainage characteristics. 3. Select plateaus in the eastern forested regions, where clearing would be required but elevation advantages might offset this investment. The coastal areas, while flat and open, may be less suitable due to higher land values, environmental protections, and potential tourism impacts. Additionally, the river valleys, particularly along the Lagan, present more complex topography that would complicate large-scale installations, though smaller projects might find suitable sites on south-facing valley slopes.
