The location at Haniska, Košice Region, Slovakia, is moderately suitable for generating energy via solar photovoltaic (PV) systems year-round. The amount of electricity that can be produced from the sun's rays varies throughout the year due to changes in weather and sunlight intensity.
During summer, each kilowatt of installed solar power can produce an average of 6.24 kilowatt-hours per day. This is the ideal time for solar power generation because longer daylight hours and higher sunlight intensity allow for maximum energy production.
In autumn, the output drops to about 2.92 kilowatt-hours per day per kilowatt installed due to shorter days and lower sunlight intensity as a result of changing seasons.
Winter sees the lowest output with just 1.32 kilowatt-hours generated daily per installed kilowatt because there are fewer hours of daylight and often cloudier skies.
Spring sees a rise again with around 4.51 kWh/day/kW as days start getting longer and sunnier again after winter.
For fixed panel installations at this location, tilting panels at an angle of 41 degrees towards South would maximise total yearly production from solar PV by catching more direct sunlight over the course of a day all through out different seasons.
However, local factors such as weather conditions could potentially impact solar production in Haniska; cloudy or snowy days may reduce energy yield since they block direct sunlight reaching your panels which is needed for optimal performance.
To mitigate these issues:
- Regular maintenance including cleaning off any snow or debris on panels will help ensure they operate efficiently.
- Using advanced PV modules designed to perform better under low light conditions can also be beneficial.
- Installing trackers could also increase efficiency by allowing panels to follow sun’s path during daytime.
Remember though that while these measures might improve performance somewhat during less-than-optimal periods like winter or cloudy days; no measure will completely overcome lack of sufficient light which fundamentally limits how much energy solar panels can produce.
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 64 locations across Slovakia. 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 Haniska
Seasonal solar PV output for Latitude: 48.6201, Longitude: 21.2565 (Haniska, 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 41° South in Haniska, Slovakia
To maximize your solar PV system's energy output in Haniska, Slovakia (Lat/Long 48.6201, 21.2565) throughout the year, you should tilt your panels at an angle of 41° 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 Haniska, 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 Haniska, Slovakia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 41° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 32° South in Summer | 52° South in Autumn | 62° South in Winter | 41° 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 Haniska, 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 Haniska, 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 Haniska, Slovakia
Haniska, Slovakia is located in the eastern part of the country, near the city of Kosice. The topography around Haniska generally consists of flat to gently rolling plains with some hilly areas. The region is characterized by a mix of agricultural land, forests, and urban areas.
For large-scale solar photovoltaic (PV) installations, flat or gently sloping lands are typically preferred as they require less groundwork and can accommodate more solar panels per unit area. Therefore, the plains around Haniska could be suitable for such projects.
However, there are several other factors that should also be considered when choosing a site for a large-scale solar PV project:
1. Solar Radiation: This is perhaps the most important factor. Eastern Slovakia receives relatively good levels of sunlight throughout the year which makes it suitable for solar energy generation.
2. Land Use: Agricultural lands may not be ideal for setting up large-scale solar PV projects due to potential conflicts with food production and local farming communities.
3. Proximity to Power Grid: Large-scale PV installations need to connect to power grids for electricity transmission so proximity to existing infrastructure would be beneficial.
4. Environmental Impact: Any potential environmental impacts must also be taken into account including effects on local wildlife or protected natural areas.
5. Local Regulations and Policies: These can greatly affect feasibility and profitability of such projects so understanding them thoroughly would be crucial before making any decisions.
In summary, while certain parts around Haniska might seem physically suited based on topography alone for large scale Solar PV systems; actual suitability would depend upon many other factors like those mentioned above.
Slovakia solar PV Stats as a country
Slovakia ranks 46th in the world for cumulative solar PV capacity, with 535 total MW's of solar PV installed. This means that 2.40% of Slovakia's total energy as a country comes from solar PV (that's 33rd in the world). Each year Slovakia is generating 98 Watts from solar PV per capita (Slovakia ranks 39th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Slovakia?
Yes, there are incentives for businesses wanting to install solar energy in Slovakia. The Slovak 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 Slovak government has set up a Renewable Energy Support Scheme (RES) which provides additional funding for renewable energy projects such as solar installations.
