Solar PV Analysis of Dol Pri Ljubljani, Slovenia
Dol pri Ljubljani, Slovenia, has varying potential for solar energy production throughout the year. During summer, you can expect to generate quite a bit of electricity from solar panels - about 6.55 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar power. The output drops in autumn to around 3.02 kWh/day per kW, and it's even lower in winter at approximately 1.84 kWh/day per kW. However, it picks up again in spring with an average production of about 4.66 kWh/day per kW.
In simple terms, this means that the best time to generate solar energy at this location is during the summer when the sun shines brightest and longest; spring is also a good time but not as productive as summer. Autumn and winter have less sunlight hours due to shorter days and more cloud cover which reduces your overall output.
For fixed panel installations at this location, tilting your panels at an angle of 39 degrees facing south would allow you to maximize total year-round production from your solar PV system.
As far as environmental or weather factors are concerned that could impede solar production at this location: Dol pri Ljubljani experiences a temperate climate with four distinct seasons including wet winters which could potentially reduce sunlight exposure on some days due to increased cloud cover or snowfall covering the panels temporarily.
To prevent these issues from affecting your energy generation significantly:
1) Regular maintenance and cleaning should be carried out especially after heavy snowfall or rainfall events to keep panels clear.
2) Consider installing automated systems that can adjust panel angles according to seasonal changes or daily sun positions.
3) Also consider using high-efficiency photovoltaic cells that work well even under cloudy conditions.
4) If possible install additional storage capacity like batteries so excess power generated during sunny periods can be stored for use during less sunny times.
Remember, even though there are challenges, with the right setup and maintenance, you can still generate a significant amount of solar energy at this location.
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 Dol Pri Ljubljani
Seasonal solar PV output for Latitude: 46.0855, Longitude: 14.5981 (Dol Pri Ljubljani, 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 39° South in Dol Pri Ljubljani, Slovenia
To maximize your solar PV system's energy output in Dol Pri Ljubljani, Slovenia (Lat/Long 46.0855, 14.5981) throughout the year, you should tilt your panels at an angle of 39° 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 Dol Pri Ljubljani, 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 Dol Pri Ljubljani, Slovenia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 29° South in Summer | 49° 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 Dol Pri Ljubljani, 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 Dol Pri Ljubljani, 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 Dol Pri Ljubljani, Slovenia
The topography around Dol pri Ljubljani, Slovenia is characterized by a mix of flat plains and hilly terrain. The area is part of the Central Sava Valley, which is surrounded by the Kamnik-Savinja Alps to the north and west, and the Dinaric Alps to the south.
As for solar PV potential, it would depend on several factors including solar irradiance levels (amount of sunlight), land availability and suitability (e.g., not used for agriculture or protected natural areas), local regulations, etc.
Generally speaking though:
1) Flat areas are typically more suited for large-scale ground-mounted solar PV installations due to ease of installation and maintenance.
2) South-facing slopes in hilly areas can also be good locations as they receive more sunlight throughout the day compared to north-facing slopes.
3) Rooftops in urban or industrial zones could also be considered for smaller-scale distributed solar PV systems.
Specifically in this region:
- The flatter plains around Ljubljana could potentially accommodate larger ground-mounted systems.
- Hilly regions with south-facing slopes might be suitable if they're not too steep or forested.
- Urbanized areas like Domžale or Ljubljana itself may have rooftop potential.
However, these are just general possibilities. A detailed site-specific assessment would need to be conducted taking into account various technical, environmental and socio-economic factors before determining actual feasibility.
Slovenia solar PV Stats as a country
