Solar PV Analysis of Orehova Vas, Slovenia
Orehova Vas, Slovenia, situated at latitude 46.4698 and longitude 15.6643, presents a mixed picture for year-round solar PV energy generation. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which affects the overall efficiency of solar installations.
Seasonal Solar Performance
The solar energy production in Orehova Vas follows a predictable pattern aligned with the changing seasons. Summer stands out as the most productive period, with an impressive daily output of 6.55 kWh per kW of installed solar capacity. Spring follows as the second most productive season, generating 4.66 kWh per day. Autumn sees a considerable drop in production to 3.02 kWh per day, while winter experiences the lowest output at just 1.84 kWh per day.
Optimal Installation Angle
For fixed panel installations in Orehova Vas, the ideal tilt angle to maximize year-round solar production is 40 degrees facing South. This angle has been calculated to optimize energy capture across all seasons, taking into account the location's latitude and the Earth's elliptical orbit.
Best Times for Solar Generation
The most favorable period for solar energy production in Orehova Vas is from late spring through early autumn. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. The peak generation typically occurs around the summer solstice in June, when day length is at its maximum.
Environmental and Weather Factors
While Orehova Vas generally offers good conditions for solar energy production, there are some factors that could potentially impact efficiency:
- Snow accumulation in winter months can temporarily reduce panel output
- Fog, which is common in the region, may decrease solar irradiance on some days
To mitigate these issues, installing panels at the recommended 40-degree angle can help shed snow more easily. Regular cleaning and maintenance, especially after snowfall, can also ensure optimal performance. For fog-related concerns, using high-efficiency panels that perform well in diffuse light conditions can help maintain productivity.
Despite these challenges, with proper installation and maintenance, solar PV systems in Orehova Vas can still provide significant energy output, particularly during the more productive months of the year.
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 Orehova Vas
Seasonal solar PV output for Latitude: 46.4698, Longitude: 15.6643 (Orehova Vas, 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 Orehova Vas, Slovenia
To maximize your solar PV system's energy output in Orehova Vas, Slovenia (Lat/Long 46.4698, 15.6643) 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 Orehova Vas, 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 Orehova Vas, 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 | 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 Orehova Vas, 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 Orehova Vas, 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 Orehova Vas, Slovenia
The area around Orehova Vas, Slovenia, is characterized by a diverse and picturesque landscape typical of the eastern Slovenian region. Located in the northeastern part of the country, this area is part of the Drava Plain, which is generally flat to gently rolling terrain.
The immediate surroundings of Orehova Vas feature a mix of agricultural fields, small patches of forest, and scattered settlements. The land is predominantly low-lying, with elevations ranging from about 250 to 300 meters above sea level. This relatively flat topography is punctuated by occasional small hills and shallow valleys created by local streams and rivers.
To the south and southeast of Orehova Vas, the terrain gradually becomes more hilly as it transitions into the foothills of the Pohorje mountain range. These hills are often covered with mixed forests and offer a contrast to the more open landscapes of the plain.
The Drava River, one of Slovenia's major waterways, flows several kilometers to the north of Orehova Vas. Its wide valley has shaped much of the local topography, creating fertile alluvial plains that are extensively used for agriculture.
Regarding areas suitable for large-scale solar PV installations, the flat or gently sloping agricultural lands in the Drava Plain would be most appropriate. These areas offer several advantages for solar energy production:
- They receive ample sunlight due to their open, unobstructed nature.
- The relatively level ground reduces the need for extensive land preparation.
- There is often good access to existing infrastructure, such as roads and power grids.
- These areas are typically less ecologically sensitive compared to forested or mountainous regions.
Specifically, the agricultural fields to the north and northeast of Orehova Vas, extending towards the towns of Miklavž na Dravskem polju and Starše, could be suitable locations. These areas combine favorable topography with proximity to local infrastructure.
However, it's important to note that any large-scale solar development would need to balance energy production goals with preserving valuable agricultural land and considering local environmental and community impacts. Detailed site-specific studies would be necessary to determine the most appropriate locations for solar PV installations in this region.
