Solar PV Analysis of Tjorhom, Norway
In Tjorhom, Agder, Norway, the potential for solar photovoltaic (PV) power generation varies across different seasons. During the summer months, when daylight hours are extended and sunlight is abundant, an average of 5.67 kilowatt-hours (kWh) per day can be generated for each kilowatt (kW) of installed solar capacity. As autumn arrives, this figure decreases to approximately 1.52 kWh/day per kW due to shorter daylight hours and less intense sunlight.
The winter season sees a further reduction in solar production with an average yield of only 0.68 kWh/day per kW because of the even shorter days and lower sun intensity typical during this time of year in Norway. However, as spring emerges with longer daylight hours and stronger sunlight compared to winter months, the daily energy production increases again to around 4.12 kWh/day per kW.
To optimize energy capture from the sun at this location throughout all seasons, it is recommended that fixed solar panels are installed at a tilt angle facing 49 degrees South.
However, there are certain environmental factors in Tjorhom that could potentially impede optimal solar energy production. Inclement weather conditions such as heavy snowfall or thick fog can obstruct incident sunlight from reaching the panels effectively reducing their efficiency considerably.
To mitigate these potential obstacles and ensure greater energy output year-round from your PV installation in Tjorhom despite local weather challenges; it's advisable to incorporate preventive measures during installation such as equipping your system with snow guards or automated cleaning systems which help maintain unobstructed exposure to incident light on your panels by removing snow build-up or other debris promptly.
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.

Solar output per kW of installed solar PV by season in Tjorhom
Seasonal solar PV output for Latitude: 58.9297, Longitude: 6.8968 (Tjorhom, 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 49° South in Tjorhom, Norway
To maximize your solar PV system's energy output in Tjorhom, Norway (Lat/Long 58.9297, 6.8968) throughout the year, you should tilt your panels at an angle of 49° 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 Tjorhom, 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 Tjorhom, Norway. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 49° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 43° South in Summer | 61° South in Autumn | 72° 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 Tjorhom, 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 Tjorhom, 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 Tjorhom, Norway
The topography around Tjorhom, Norway is mostly flat with some rolling hills. The nearby areas that would be most suited for large-scale solar PV are the flatlands and low-lying areas near the coast. These areas have good access to sunlight and are more likely to have fewer obstructions from trees or buildings. Additionally, the coastal area is often windier than inland locations, which can help increase energy production from PV systems.
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.
