The location at Kresnice, Občina Moravče, Slovenia, situated at 46.1059 latitude and 14.7873 longitude, presents varying levels of suitability for solar PV energy generation throughout the year. This Northern Temperate Zone location experiences significant seasonal fluctuations in solar energy production, which directly impacts the efficiency of solar installations.

Seasonal Solar Energy Production

Summer stands out as the most productive season for solar energy generation in Kresnice, Občina Moravče, with an impressive output of 6.55 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second-most productive season, yielding 4.66 kWh/day. However, the colder months see a substantial decrease in energy production, with autumn producing 3.02 kWh/day and winter dropping to a mere 1.84 kWh/day per kW installed.

The ideal times for solar energy generation at this location are from late spring through early autumn, typically spanning from May to September. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency.

Optimal Panel Installation

To maximize year-round solar energy production in Kresnice, Občina Moravče, fixed solar panels should be installed at a tilt angle of 39 degrees facing south. This angle has been calculated to optimize energy capture across all seasons, taking into account the Earth's elliptical orbit and the location's specific latitude.

Environmental and Weather Considerations

While Kresnice generally offers favorable conditions for solar energy production, there are some environmental and weather factors that could potentially impact solar panel efficiency:

1. Snow accumulation in winter months can temporarily reduce panel output.
2. Fog and overcast conditions, which are more common in autumn and winter, may decrease solar irradiance.

To mitigate these issues, consider implementing the following preventative measures:

• Install panels at a steeper angle to promote snow sliding off
• Use anti-reflective coatings on panels to improve performance in low-light conditions
• Implement a regular cleaning schedule to remove any debris or snow
• Consider using bifacial panels to capture reflected light, potentially increasing energy production

By taking these factors into account and implementing appropriate measures, solar PV installations in Kresnice can achieve optimal energy production throughout the year, despite seasonal variations and potential environmental challenges.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Kresnice

Seasonal solar PV output for Latitude: 46.1059, Longitude: 14.7873 (Kresnice, 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 Kresnice, Slovenia

To maximize your solar PV system's energy output in Kresnice, Slovenia (Lat/Long 46.1059, 14.7873) 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 Kresnice, 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 Kresnice, 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 Kresnice, 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 Kresnice, Slovenia.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Kresnice, Slovenia

The area surrounding Kresnice, Slovenia, is characterized by a diverse and picturesque topography typical of the region's transition between the Alps and the Pannonian Basin. Located in central Slovenia, Kresnice sits along the Sava River, which has carved a scenic valley through the landscape over millennia. The immediate vicinity of Kresnice features a mix of gently rolling hills and flat riverside areas. The Sava River valley provides a relatively wide and level expanse, with fertile alluvial soils supporting agriculture and settlements. As one moves away from the river, the terrain becomes more undulating, with hills rising on both sides of the valley. To the north and west of Kresnice, the landscape gradually becomes more mountainous, with forested slopes and steeper inclines leading towards the foothills of the Alps. These areas are part of the Posavsko hribovje, a hilly region that serves as a natural boundary between the Alpine and Pannonian regions of Slovenia.

Potential for Solar PV Development

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations would combine favorable topography with good solar exposure and minimal environmental impact. The flatter areas along the Sava River valley, particularly on the outskirts of settlements, could offer potential sites for solar farms. These locations benefit from level ground, which simplifies construction and maintenance of solar arrays. However, care must be taken to avoid prime agricultural land and areas prone to flooding. South-facing slopes of the surrounding hills might also be suitable for solar PV installations. These areas can receive more direct sunlight throughout the day, potentially increasing the efficiency of solar panels. However, developers would need to carefully assess the steepness of the terrain and the potential impact on local ecosystems and forest cover. Former industrial sites or brownfield areas in the broader region could be repurposed for solar energy production. These locations often have the advantage of existing infrastructure and minimal conflict with other land uses. It's important to note that while the topography around Kresnice offers some potential for solar PV development, any large-scale projects would require thorough environmental impact assessments and must comply with local and national regulations. The region's natural beauty and ecological significance mean that careful planning and community engagement would be essential for any significant solar energy initiatives.
