Solar PV Analysis of Ravne Na Koroskem, Slovenia
The location at Ravne na Koroskem, Slovenia is moderately suitable for generating energy via solar photovoltaic (PV) systems all year round. However, the effectiveness of this system varies with each season due to changes in sunlight intensity and duration.
During summer, the solar PV system can generate an average of 6.55 kilowatt-hours (kWh) per day for every kilowatt (kW) installed. This makes summer the best time to generate solar energy at this location because of longer daylight hours and more intense sunlight.
In autumn and spring, the output drops to 3.02 kWh/day and 4.66 kWh/day respectively per kW installed as a result of shorter daylight hours compared to summer.
Winter sees the lowest production level with only about 1.84 kWh/day generated per kW installed due to even shorter daylight hours and less intense sunlight caused by cloud cover or foggy conditions that are common during winter months.
For fixed panel installations at this location, tilting panels at an angle of approximately 40 degrees towards South would maximize total year-round production from solar PV systems because it allows them to capture more sunlight throughout different times of day across all seasons.
There could be environmental or weather factors that might impede solar production in Ravne na Koroskem like heavy snowfall during winter or frequent cloudy days which reduce sunlight exposure on panels. To overcome these issues:
1) Regular cleaning: Snow accumulation on panels should be cleared regularly so they can better absorb sunlight.
2) Using high-quality PV modules: These have better performance under low light conditions.
3) Installing trackers: Trackers help panels follow sun’s movement thus maximizing exposure even on cloudy days.
4) Proper installation: Ensuring professional installation helps avoid shading issues from nearby buildings or trees that could block direct sun exposure on panels.
By considering these measures when installing a solar PV system in Ravne na Koroskem, you can ensure greater energy production despite the seasonal and environmental challenges.
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 60 locations across Slovenia. 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 Ravne Na Koroskem
Seasonal solar PV output for Latitude: 46.5414, Longitude: 14.9675 (Ravne Na Koroskem, Slovenia), 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 40° South in Ravne Na Koroskem, Slovenia
To maximize your solar PV system's energy output in Ravne Na Koroskem, Slovenia (Lat/Long 46.5414, 14.9675) throughout the year, you should tilt your panels at an angle of 40° 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 Ravne Na Koroskem, Slovenia
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 Ravne Na Koroskem, Slovenia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 30° South in Summer | 50° South in Autumn | 60° South in Winter | 39° 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 Ravne Na Koroskem, Slovenia
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 Ravne Na Koroskem, Slovenia.
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 Ravne Na Koroskem, Slovenia
Ravne na Koroskem is located in the mountainous region of Slovenia, surrounded by the Pohorje Mountains and the Karavanke Alps. The terrain is characterized by steep slopes, valleys, and dense forests.
Despite being in a mountainous area, there are still potential locations for large-scale solar PV installations. Flat areas with good sun exposure such as valleys or cleared forest lands could be suitable. However, these installations would need to consider environmental impacts and local regulations regarding land use.
In addition to this, rooftops of buildings in urban areas like Ravne na Koroskem town itself can also be utilized for smaller scale solar PV projects. This approach has less impact on natural landscapes and does not require additional land.
Furthermore, south-facing slopes that receive ample sunlight throughout the year might also be considered for solar PV installations provided they meet necessary criteria including accessibility, slope stability etc., but this would likely involve more complex installation processes due to the sloping terrain.
Given Slovenia's commitment towards renewable energy sources and its abundant sunshine during summer months (especially considering it's one of Europe's sunniest countries inland), exploring options for large-scale solar power generation seems feasible despite topographical challenges.
It should be noted that any decision on where to install a large-scale solar PV should include careful site assessment which includes not just topography but also factors like local climate conditions (amount of sunlight received), soil type/stability/compatibility with construction needs etc., existing infrastructure/accessibility/logistics considerations among others.
Slovenia solar PV Stats as a country
Slovenia ranks 60th in the world for cumulative solar PV capacity, with 367 total MW's of solar PV installed. Each year Slovenia is generating 175 Watts from solar PV per capita (Slovenia ranks 28th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Slovenia?
Yes, there are incentives for businesses wanting to install solar energy in Slovenia. The Slovenian government offers a range of financial incentives and subsidies for businesses that install solar energy systems. These include grants, tax credits, and other forms of support. Additionally, the government has set up a number of programs to promote the use of renewable energy sources such as solar power.
