Solar PV Analysis of Jesenice, Czechia
Jesenice, Central Bohemia, Czechia, situated at coordinates 49.9627, 14.5168, presents a mixed picture for solar PV energy generation throughout the year. Located in the Northern Temperate Zone, this area experiences significant seasonal variations in solar output.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive daily output of 5.86 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 4.22 kWh/day. However, the colder months see a substantial drop in production, with autumn yielding 2.64 kWh/day and winter plummeting to a mere 1.21 kWh/day.
These figures indicate that Jesenice is well-suited for solar energy production during the warmer months, particularly from late spring through early autumn. However, the stark contrast between summer and winter output suggests that relying solely on solar power year-round may be challenging without significant energy storage solutions or supplementary power sources.
Optimal Panel Installation
To maximize year-round solar energy production in Jesenice, Central Bohemia, fixed solar panels should be installed at a tilt angle of 42 degrees facing south. This angle has been carefully calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the location's latitude and the Earth's elliptical orbit.
Environmental and Weather Considerations
While Jesenice's location is generally favorable for solar energy production, there are some environmental factors to consider:
- Snow accumulation in winter can significantly reduce panel efficiency.
- Frequent cloudy days, especially during autumn and winter, may impact overall production.
To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding off and using high-efficiency panels that perform better in low-light conditions. Regular maintenance, including snow removal and cleaning, can also help maintain optimal performance.
In conclusion, while Jesenice's location presents challenges for year-round solar energy production, proper installation techniques and maintenance can still make solar PV a viable option, especially when combined with other energy sources or storage solutions to compensate for the lower winter output.
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 74 locations across Czechia. 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 Jesenice
Seasonal solar PV output for Latitude: 49.9627, Longitude: 14.5168 (Jesenice, Czechia), 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 42° South in Jesenice, Czechia
To maximize your solar PV system's energy output in Jesenice, Czechia (Lat/Long 49.9627, 14.5168) throughout the year, you should tilt your panels at an angle of 42° 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 Jesenice, Czechia
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 Jesenice, Czechia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 42° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 33° South in Summer | 53° South in Autumn | 63° South in Winter | 42° 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 Jesenice, Czechia
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 Jesenice, Czechia.
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 Jesenice, Czechia
The area around Jesenice, Czechia, is characterized by gently rolling hills and shallow valleys typical of the Central Bohemian region. The landscape is a mix of agricultural fields, patches of forest, and small settlements. The terrain is generally mild, with gradual slopes and elevations ranging from about 300 to 400 meters above sea level.
To the north and east of Jesenice, the land becomes slightly more elevated, forming part of the Brdy Highlands. This area features more forested regions and steeper hillsides. To the south and west, the terrain is relatively flatter, with open fields and meadows dominating the landscape.
The Sázava River valley lies a few kilometers to the south of Jesenice, creating a more dramatic topographical feature with steeper slopes leading down to the river.
Areas Suitable for Large-Scale Solar PV
For large-scale solar photovoltaic (PV) installations, the most suitable areas near Jesenice would be:
- Open agricultural land to the south and west: These areas offer relatively flat terrain with fewer obstructions, making them ideal for solar panel placement. The gentle slopes in these directions also provide good sun exposure throughout the day.
- Cleared hilltops and plateaus: Some of the higher elevation areas, if not heavily forested, could be suitable for solar farms. These locations often have excellent sun exposure and less risk of shadowing from surrounding landscape features.
- Former industrial or mining sites: If any exist in the vicinity, these brownfield areas could be repurposed for solar energy production, offering large, open spaces with existing infrastructure.
It's important to note that while these areas may be topographically suitable, other factors such as grid connectivity, local regulations, and environmental considerations would need to be assessed before developing any large-scale solar PV projects. Additionally, care should be taken to balance energy production needs with preserving the region's agricultural land and natural beauty.
