Solar PV Analysis of Koper, Slovenia
The location at Koper, Slovenia is somewhat ideal for generating energy using solar photovoltaic (PV) panels. It's not perfect, but it can still be quite effective. The amount of electricity you can get from the sun changes with the seasons. In summer, each kilowatt of installed solar can produce about 7.08 kilowatt-hours per day. This decreases to about 3.29 in autumn and goes even lower to around 1.72 in winter before rising again to around 5.46 in spring.
This means that the best times of year for generating solar energy here are during the summer and spring months when there's a lot more sunlight available compared to other seasons like winter where days are shorter and sunlight is less.
To maximize your total production from solar PV throughout the year at this location, you should tilt your panels at an angle of 39 degrees facing south if they're going to be fixed in one position.
When considering local factors that could affect your ability to generate solar power here, weather conditions such as cloud cover or heavy snowfall could reduce how much sunlight reaches your panels which would mean less electricity produced overall.
Also environmental factors like dust or bird droppings on your panels might impact their efficiency by blocking some sunlight from being absorbed - so regular cleaning may be necessary depending on local conditions.
In terms of preventative measures that can help ensure greater energy production: You could consider installing tracking systems that adjust panel angles throughout the day or year to follow the sun’s path and maximize exposure; although these come with added cost and maintenance considerations compared with fixed installations.
Another option might involve investing in higher-efficiency modules which perform better under low-light conditions; though again these tend to cost more upfront than standard models.
You may also want to install additional capacity (more kW) than initially estimated if you expect significant seasonal variation or potential blockages/losses – so as to ensure enough power generation even during less ideal times or conditions.
Lastly, it's always a good idea to consult with local experts who can provide specific advice based on the unique characteristics of your location and installation.
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 Koper
Seasonal solar PV output for Latitude: 45.5565, Longitude: 13.7418 (Koper, 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 Koper, Slovenia
To maximize your solar PV system's energy output in Koper, Slovenia (Lat/Long 45.5565, 13.7418) 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 Koper, 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 Koper, 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 | 38° 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 Koper, 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 Koper, 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 Koper, Slovenia
Koper, Slovenia is located on the Adriatic Sea and is characterized by a mix of flat coastal areas and rolling hills inland. The region enjoys a Mediterranean climate with plenty of sunshine throughout the year.
The topography in the immediate vicinity of Koper is relatively flat, especially towards the coast. However, as you move further inland towards the east or northeast, it becomes more hilly and mountainous with elevations increasing considerably. This area falls within the broader region known as Slovenian Istria which consists of several valleys interspersed with low hills.
For large-scale solar PV installations, it would be ideal to look for expansive flat areas that receive ample sunlight throughout the year. In this context, considering both topographical and climatic factors:
1) Coastal Areas: The coastal plains around Koper could potentially serve as suitable locations for large-scale solar farms due to their flatness and high levels of insolation (sunlight exposure).
2) Valleys: Some valleys in Slovenian Istria might also be appropriate if they are wide enough to accommodate large solar arrays and oriented in such a way that they receive sufficient sunlight throughout most of the day.
However, any proposal for installing solar panels should consider local land use regulations, potential environmental impacts (like effects on local flora/fauna), proximity to power grids for easy transmission & distribution etc., along with topography and climate conditions.
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.
