Alta, Norway, situated at a latitude of 69.9688853 and longitude of 23.2715873, offers varying levels of solar energy production throughout the year. During the summer season, an average of 4.99 kWh per day per kW of installed solar can be expected, while in spring this figure is slightly lower at 4.15 kWh per day per kW. However, autumn and winter see significantly reduced solar generation with averages of 0.77 kWh and 0.13 kWh per day per kW respectively.
Given its location within the Arctic Circle, Alta faces certain challenges when it comes to harnessing solar power year-round. The shorter daylight hours during winter months limit the amount of sunlight available for energy production, while snowfall may cover panels or cause them to malfunction due to cold temperatures or ice buildup.
To mitigate these issues and ensure optimal energy production from solar installations in Alta, several preventative measures can be taken:
1) Installing panels at an ideal tilt angle: For fixed panel installations in Alta, tilting the panels at a 58-degree angle towards the south will maximize their exposure to sunlight throughout the year.
2) Regular maintenance: Clearing snow and ice from panels as needed will help maintain their efficiency during colder months.
3) Wind protection: Strong winds can both clear snow from panels but also increase wind chill temperatures which may affect panel performance; installing wind barriers or choosing a sheltered location for installation could help reduce these effects.
In conclusion, although Alta's location presents some challenges for generating solar power consistently throughout the year due to seasonal variations in sunlight availability and weather conditions such as snowfall and strong winds, careful planning and implementation can still make it a viable option for renewable energy generation in this region.
Note: The Artic Circle includes any location with a latitude North of 66.5°.
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.

Solar output per kW of installed solar PV by season in Alta
Seasonal solar PV output for Latitude: 69.9688853, Longitude: 23.2715873 (Alta, 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 58° South in Alta, Norway
To maximize your solar PV system's energy output in Alta, Norway (Lat/Long 69.9688853, 23.2715873) throughout the year, you should tilt your panels at an angle of 58° 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 Alta, 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 Alta, Norway. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 58° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 53° South in Summer | 70° South in Autumn | 78° South in Winter | 61° 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 Alta, 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 Alta, Norway.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Alta, Norway
The topography around Alta, Norway is generally flat with some rolling hills and mountains in the surrounding area. The nearby areas that are most suitable for large-scale solar PV projects are those that have clear access to direct sunlight, such as open fields or rooftops with minimal shading. Areas that are closer to the coast may also be suitable depending on weather patterns and wind protection.
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. This includes grants, loans, and tax deductions. Additionally, the Norwegian Energy Agency provides funding for research and development projects related to renewable energy technologies. Finally, the Norwegian Power Company (Statkraft) offers discounted electricity rates for businesses that use solar power.
