Solar Energy Generation in Nesttun, Vestland, Norway

Nesttun, Vestland, Norway, located at 60.3187° North, 5.3504° East in the Northern Temperate Zone, presents significant seasonal variations for solar PV energy production. This location experiences dramatic differences in solar energy generation throughout the year, making it less than ideal for consistent year-round solar power production. The seasonal electricity output from a 1kW solar installation in Nesttun shows a stark contrast between summer and winter. During summer months, the system can generate a respectable 5.27kWh per day. Spring also offers good generation potential with 4.03kWh daily. However, autumn production drops significantly to just 1.21kWh per day, while winter performance plummets to a minimal 0.46kWh daily.

Optimal Installation Parameters

For fixed solar panel installations in Nesttun, Vestland, the ideal tilt angle to maximize year-round energy production is 50 degrees facing South. This specific angle has been calculated to optimize the annual solar harvest considering the location's northern latitude and seasonal sun path variations.

Environmental and Weather Considerations

Several significant factors can impede solar production at this location:

• Heavy snowfall during winter months can cover panels and virtually eliminate production during the already low-yield winter season
• Frequent cloud cover and precipitation in the Bergen region where Nesttun is located
• Potential shading from surrounding mountains or tall buildings, common in Norwegian topography
• Salt spray exposure for installations closer to the fjords

To mitigate these challenges, several preventative measures can be implemented. Installing panels at the steep 50-degree angle not only optimizes year-round production but also helps shed snow more effectively. Using micro-inverters or power optimizers can minimize production losses from partial shading. Regular cleaning and maintenance, especially after snowfall, is essential. Additionally, high-efficiency panels designed for low-light conditions can improve performance during cloudy periods typical of western Norway. Given the extreme seasonal variation, homeowners in Nesttun should consider solar as part of a hybrid energy system rather than a standalone solution, with greatest production occurring from April through August, and minimal contribution during the November to February period.

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 Nesttun

Seasonal solar PV output for Latitude: 60.3187, Longitude: 5.3504 (Nesttun, Norway), 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 50° South in Nesttun, Norway

To maximize your solar PV system's energy output in Nesttun, Norway (Lat/Long 60.3187, 5.3504) throughout the year, you should tilt your panels at an angle of 50° 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 Nesttun, Norway

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 Nesttun, Norway. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 50° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
44° South in Summer	62° South in Autumn	73° 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 Nesttun, Norway

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 Nesttun, Norway.

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 Nesttun, Norway

The terrain surrounding Nesttun, Norway presents a diverse topographic landscape characteristic of western Norwegian fjord regions. Situated approximately 10 kilometers south of Bergen city center, Nesttun lies in a valley area surrounded by notable elevation changes. The immediate vicinity features a combination of rolling hills, small valleys, and modest mountains that create a varied landscape.

Valley Setting

Nesttun itself occupies a relatively flat valley floor positioned between higher terrain. This valley runs roughly north-south, following the path of local waterways. The settlement developed naturally in this sheltered position, with mountains rising on both eastern and western sides. The valley floor sits at approximately 40-60 meters above sea level, providing a natural corridor for transportation routes connecting Bergen with areas further south.

Surrounding Elevations

The hills and mountains surrounding Nesttun range from modest elevations of 200-300 meters to more substantial peaks reaching 400-500 meters in the wider vicinity. These elevations are part of the characteristic fjord landscape of western Norway, formed through glacial activity during the last ice age. The terrain generally rises more steeply to the east of Nesttun, with somewhat gentler slopes characterizing the western approaches. Notable among the nearby mountains is Løvstakken to the northwest, reaching approximately 477 meters, and Ulriken further north at about 643 meters. These mountains form part of the "Seven Mountains" that surround the larger Bergen area.

Hydrological Features

The area contains several small lakes and waterways. The Nesttunvassdraget (Nesttun waterway) flows through the valley, connecting a series of small lakes including Nesttunvatnet. These water features have historically played important roles in local industry and settlement patterns. The combination of valleys, waterways, and surrounding hills creates a landscape with numerous microclimates and varying sun exposure conditions.

Suitability for Solar PV Development

For large-scale solar photovoltaic installations, several factors must be considered in this topographically complex region. The most suitable areas would generally be:

South-Facing Slopes

The most promising locations for solar development are the south-facing hillsides surrounding Nesttun. These slopes receive more direct sunlight throughout the year compared to other orientations. Particularly valuable are the moderately inclined south-facing aspects between 100-300 meters elevation that aren't shadowed by higher mountains. These areas maximize solar gain while potentially avoiding some of the coastal fog and cloud cover that affects lower elevations.

Cleared Highland Areas

Some of the more gently sloping highland areas above 200 meters elevation could offer potential for solar installations, particularly where vegetation is naturally sparse or where land has already been cleared. These higher elevations sometimes rise above low-lying cloud cover that can affect valleys, potentially increasing solar exposure.

Challenges and Limitations

The topography presents several challenges for large-scale solar development. The steep nature of many slopes makes construction difficult and expensive. Additionally, the complex terrain creates significant shading patterns that change throughout the day and seasons. The numerous north-facing slopes receive substantially less direct sunlight and would be unsuitable for efficient solar production. Furthermore, the region experiences considerable precipitation and cloud cover associated with its coastal proximity and mountainous terrain. The western Norwegian climate, influenced by the North Atlantic, features frequent overcast conditions that would impact solar efficiency regardless of topographical positioning. Valley floors, while easier to develop from a construction perspective, often experience more fog and shadow effects from surrounding mountains, potentially limiting their suitability for optimal solar production.

Norway solar PV Stats as a country

Norway ranks 70th in the world for cumulative solar PV capacity, with 225 total MW's of solar PV installed.
