Bellova Ves, Trnava Region, Slovakia presents a moderately suitable location for solar photovoltaic energy generation, though with significant seasonal variations typical of its Northern Temperate Zone climate. The location experiences considerable differences in solar energy production throughout the year.
Seasonal Solar Energy Production
Summer represents the peak solar generation period at Bellova Ves, Trnava Region, producing 6.37kWh per day per kW of installed solar capacity. This makes summer the most productive season for solar energy generation at this location. Spring follows as the second-best season with 4.49kWh per day per kW, making it another favorable period for solar production. Autumn production drops significantly to 2.82kWh per day per kW, while winter presents the most challenging conditions with only 1.26kWh per day per kW of installed capacity. This dramatic winter reduction is typical for locations at this latitude in Central Europe. For optimal year-round energy production, fixed solar panels should be installed at a 40-degree tilt angle facing south. This angle maximizes total annual solar output by accounting for the sun's varying position throughout the seasons and the location's specific latitude.Environmental and Weather Factors
Several environmental and weather factors can impact solar production efficiency at Bellova Ves:- Snow accumulation during winter months can completely block solar panels
- Frequent cloud cover and fog, particularly during autumn and winter seasons
- Dust and pollen buildup, especially during spring months
- Potential shading from nearby buildings or vegetation
Preventative Measures for Enhanced Production
To maximize solar energy production despite these challenges, several installation strategies should be considered:- Install panels with adequate spacing and accessibility for snow removal
- Consider steeper tilt angles in areas with heavy snowfall to encourage natural snow shedding
- Implement regular cleaning schedules, particularly during pollen season
- Conduct thorough shade analysis before installation to avoid obstructions
- Use high-quality mounting systems that can withstand weather variations
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 Bellova Ves
Seasonal solar PV output for Latitude: 48.0921, Longitude: 17.5123 (Bellova Ves, Slovakia), 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 Bellova Ves, Slovakia
To maximize your solar PV system's energy output in Bellova Ves, Slovakia (Lat/Long 48.0921, 17.5123) 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 Bellova Ves, Slovakia
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 Bellova Ves, Slovakia. 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 |
|---|---|---|---|
| 31° South in Summer | 51° South in Autumn | 62° South in Winter | 40° 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 Bellova Ves, Slovakia
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 Bellova Ves, Slovakia.
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 Bellova Ves, Slovakia
Topographical Features of Bellova Ves and Surroundings
Bellova Ves sits in the southwestern region of Slovakia, positioned within the broader Danubian Lowland that characterizes much of the country's southern territory. This area forms part of the extensive Pannonian Basin, creating a predominantly flat to gently undulating landscape that extends across much of the region. The terrain around Bellova Ves is characterized by low-lying plains and subtle elevation changes, with the land generally sloping very gradually toward the Danube River system.
The immediate vicinity features agricultural fields and scattered settlements typical of this fertile lowland region. Small streams and drainage channels meander through the landscape, creating minor topographical variations but nothing that significantly alters the overall flat character of the area. The elevation changes are minimal, with most of the surrounding terrain remaining within a relatively narrow band of heights above sea level.
Moving outward from Bellova Ves, the landscape maintains its gentle character for considerable distances. To the north and northeast, the terrain begins a very gradual rise toward the foothills of the Carpathian mountain system, but this transition occurs over many kilometers. The western and southern directions continue the flat agricultural pattern that dominates the Danubian plains, while eastward the landscape remains consistently level as it approaches the Danube River corridor.
Optimal Areas for Large-Scale Solar Development
The flat to gently rolling topography surrounding Bellova Ves presents excellent opportunities for large-scale solar photovoltaic installations. The most suitable areas lie in the extensive agricultural plains that stretch in multiple directions from the settlement, particularly toward the south and southwest where the terrain remains consistently level over large areas.
These southern plains offer several advantages for solar development, including minimal grading requirements and the ability to install tracking systems efficiently across broad expanses. The gentle slopes that do exist generally face favorable orientations, and the absence of significant topographical obstacles means that shading between solar panel arrays can be easily managed through proper spacing.
The areas to the west and northwest of Bellova Ves also present strong potential, where the flat agricultural landscape continues uninterrupted for substantial distances. These zones benefit from the same advantageous topographical conditions while potentially offering good access to existing infrastructure networks that could support large-scale solar installations.
Less suitable for major solar developments would be the areas further north where the land begins its gradual ascent toward the Carpathian foothills. While still relatively gentle, these areas present more complex terrain that could complicate installation and maintenance activities. The immediate proximity to existing settlements and more intensive agricultural operations might also present land-use conflicts that could limit development potential in certain directions from Bellova Ves.
