Solar PV Analysis of Kolacno, Slovakia
The location at Kolacno, Trenčín Region, Slovakia seems to be a decent spot for solar energy generation throughout the year, with varying levels of effectiveness depending on the season. During summer, you can expect to generate around 6.34 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar power. This is likely the best time of year for solar production due to longer daylight hours and more direct sunlight.
In autumn, this output drops significantly to about 2.90 kWh/day per kW due to shorter days and less intense sunlight as we move away from the summer solstice. Winter sees an even further drop in production down to approximately 1.35 kWh/day per kW because of short days and low sun angles.
Springtime sees a rebound in potential energy production up to roughly 4.49 kWh/day per kW as daylight hours increase again and we approach the summer solstice.
For a fixed panel installation at this location, tilting panels at an angle of 41 degrees South would maximize total yearly solar energy production by allowing them capture more sunlight over the course of a day throughout different seasons.
As far as local factors that could impact solar PV performance in Kolacno go, it's important consider weather patterns such as cloud cover or snowfall which may reduce light exposure on panels or cover them entirely respectively; environmental factors like dust or bird droppings could also affect panel efficiency by blocking sunlight if not cleaned regularly; additionally shading from nearby buildings or trees could also impede panel performance.
To combat these issues: regular maintenance including cleaning off any debris from panels can help ensure they are working efficiently; installing panels in clear areas without shading obstacles will optimize their exposure; during winter months when snowfall is expected, having a plan for safely removing it from your panels will help maintain their productivity while preventing damage.
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 Kolacno
Seasonal solar PV output for Latitude: 48.5889, Longitude: 18.4292 (Kolacno, 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 Kolacno, Slovakia
To maximize your solar PV system's energy output in Kolacno, Slovakia (Lat/Long 48.5889, 18.4292) 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 Kolacno, 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 Kolacno, 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 Kolacno, 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 Kolacno, 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 Kolacno, Slovakia
Kolacno, Slovakia is located in a relatively flat part of the country, surrounded by low-lying hills and fertile plains. The topography is characterized by agricultural fields and some forested areas. There are also several rivers nearby.
The best places for large-scale solar PV (photovoltaic) installations would be open, flat areas with no shading from trees or buildings. This could include unused farmland or other undeveloped land that gets plenty of sunlight throughout the year.
In terms of specific locations near Kolacno, potential sites might include the open fields to the north and east of town where there appears to be less tree cover. It's also important to consider proximity to power transmission lines and infrastructure when selecting a site for a solar farm.
However, it's important to note that detailed feasibility studies would need to be conducted before any location could be confirmed as suitable for large-scale solar PV installation. These studies would take into account not only topography but also factors like local climate conditions (including average hours of sunlight), soil type, availability of grid connectivity etc.
Furthermore, such projects usually require permissions from local authorities which depend on various factors including environmental impact assessments.
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.
