The location of Asker, Akershus, Norway, situated at 59.8348°N, 10.4277°E, presents a challenging environment for year-round solar PV energy generation. Located in the Northern Temperate Zone, this area experiences significant seasonal variations in daylight hours and solar intensity, which directly impact solar energy production.

Seasonal Solar Output

Solar energy production in Asker varies dramatically throughout the year. Summer months offer the highest potential, with an average daily output of 5.72 kWh per kW of installed solar capacity. Spring follows as the second most productive season, generating 4.19 kWh/day. However, autumn and winter see a sharp decline in solar output, with 1.56 kWh/day and a mere 0.60 kWh/day, respectively.

Optimal Times for Solar Generation

The most ideal period for solar energy production in Asker is from late spring through early autumn. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. The peak generation typically occurs around the summer solstice in June, when daylight can last up to 18 hours.

Panel Installation Considerations

To maximize year-round solar production at this location, fixed solar panels should be tilted at an angle of 50 degrees facing south. This optimal angle helps capture the most sunlight throughout the year, considering the low sun angle during winter months and the higher sun position in summer.

Environmental and Weather Factors

Several factors can impede solar production in Asker:

1. Snow accumulation in winter, which can cover panels and reduce efficiency
2. Limited daylight hours during winter months, with some days receiving less than 6 hours of sunlight
3. Frequent cloud cover, particularly in autumn and winter

Preventative Measures

To mitigate these challenges, consider the following measures when installing solar PV systems in Asker:

• Use panels with anti-reflective and self-cleaning coatings to improve performance in low-light conditions and reduce snow accumulation
• Install panels at a steeper angle to encourage snow sliding off
• Implement a robust snow removal plan for winter months
• Consider using bifacial panels to capture reflected light from snow, potentially increasing winter production

While Asker's location presents challenges for year-round solar energy production, careful planning and appropriate technology can still make solar PV a viable renewable energy option, particularly during the more favorable months of the year.

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 114 locations across Norway. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 50° South in Asker, Norway

To maximize your solar PV system's energy output in Asker, Norway (Lat/Long 59.8348, 10.4277) 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.

At Latitude: 59.8348, Longitude: 10.4277, the ideal angle to tilt panels is 50° South

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

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 Asker, 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 Asker, 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 Asker, Norway

Asker, Norway, located at approximately 59.8348°N latitude and 10.4277°E longitude, is situated in a diverse topographical area characterized by a mix of coastal and inland features. The region around Asker is part of the Oslo Fjord landscape, which includes a combination of gently rolling hills, forested areas, and lowlands near the water.

The terrain in and around Asker is generally undulating, with elevations ranging from sea level along the fjord to modest hills that reach heights of around 200-300 meters above sea level. The area is dotted with small lakes, streams, and patches of forest, creating a picturesque and varied landscape. To the west of Asker, the terrain becomes more rugged and mountainous as it transitions into the Krokskogen forest area.

When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors need to be taken into account. In general, the best locations for solar farms in this region would be:

1. South-facing slopes: Gentle hillsides that face south would receive the most direct sunlight throughout the day, maximizing solar energy production.
2. Open fields: Large, flat areas with minimal shading from trees or buildings would be ideal for solar panel arrays.
3. Agricultural land: Some less productive farmland could potentially be repurposed for solar energy generation.
4. Industrial zones: Existing industrial areas or brownfield sites might offer suitable locations for solar installations.

However, it's important to note that Norway's high latitude means that solar energy potential is generally lower compared to more southern regions. The long summer days can provide good solar production during part of the year, but the short winter days and frequent cloud cover can significantly reduce efficiency.

Additionally, the hilly terrain and forested areas around Asker may limit the availability of large, unobstructed sites for solar farms. Any potential locations would need to be carefully assessed for their solar exposure, taking into account factors such as shading from nearby hills or trees, and the angle of the sun throughout the year.

Ultimately, while there may be some suitable areas for solar PV installations near Asker, the region's topography and northern latitude present challenges for large-scale solar energy production. Other renewable energy sources, such as wind or hydroelectric power, might be more viable options for this particular area.

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. This means that 0.10% of Norway's total energy as a country comes from solar PV (that's 42nd in the world). Each year Norway is generating 42 Watts from solar PV per capita (Norway ranks 55th in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in Norway?

Yes, there are several incentives for businesses wanting to install solar energy in Norway. The Norwegian government offers a range of financial support and tax breaks for businesses that invest in renewable energy sources such as solar power.
