Solar PV Analysis of Pilsen, Czechia
The location at Pilsen, Plzeň Region, Czechia, is moderately suitable for year-round solar energy generation. The amount of energy that can be produced from solar panels varies throughout the year based on the season. During summer, you can expect around 5.63 kWh per day for every kW of installed solar power, which is quite high. This means that summer is an ideal time to generate solar energy at this location due to longer daylight hours and more direct sunlight.
In autumn and winter, the expected daily output decreases significantly to 2.56 kWh and 1.25 kWh per day respectively for each kW of installed solar power due to shorter daylight hours and less direct sunlight because of the Earth's tilt away from the sun during these seasons.
During spring, production increases again up to around 4.35 kWh per day per kW installed as days start getting longer and there is more direct sunlight.
To maximize total yearly production from a fixed panel installation at this location, it's recommended that panels are tilted at an angle of 42 degrees facing South towards the equator where they will receive maximum sunlight throughout the year.
As far as environmental or local factors are concerned that could impede solar production in Pilsen; weather conditions like cloudy days or snowfall during winter might affect output by blocking sunlight reaching your panels. Additionally, topographical features like mountains or tall buildings could potentially cast shadows on your installation reducing its effectiveness.
To mitigate these issues when installing a system: Choose a spot with minimal shade throughout all times of day all-year-round; Regularly clean your panels especially after snowfall or dust storms; Install additional panels if possible so even if some are shaded others will still produce electricity; And consider using tracking systems that follow the sun’s path across sky maximizing exposure even further than fixed installations can achieve.
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 Pilsen
Seasonal solar PV output for Latitude: 49.7705, Longitude: 13.3689 (Pilsen, 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 Pilsen, Czechia
To maximize your solar PV system's energy output in Pilsen, Czechia (Lat/Long 49.7705, 13.3689) 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 Pilsen, 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 Pilsen, 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 | 52° 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 Pilsen, 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 Pilsen, 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 Pilsen, Czechia
Pilsen, also known as Plzeň, is located in the western part of Czechia. The city lies in a flat basin known as the Pilsen Basin surrounded by low hills and undulating plains. There are several rivers and streams that crisscross the region, including the Berounka River.
The topography around Pilsen is relatively flat with some gentle slopes which can be suitable for solar PV installations. However, it's important to consider factors such as local climate conditions (e.g., average hours of sunlight), land use restrictions and accessibility for installation and maintenance.
There are several areas near Pilsen that could potentially be suitable for large-scale solar PV installations:
1. Flat agricultural lands: Large tracts of agricultural land around Pilsen could potentially be used for solar farms, provided that this does not interfere with food production or local regulations.
2. Industrial zones: Unused or underutilized industrial sites can also be good locations for solar installations.
3. Rooftops: Large rooftops (e.g., on warehouses or factories) can also house solar panels without requiring additional land resources.
4. Brownfield sites: These previously developed sites that are not currently in use could be repurposed into a renewable energy source.
For precise site selection though, more detailed studies would need to be carried out considering factors such as sun exposure level throughout the year (solar irradiance), proximity to power grids for easy transmission, environmental impact assessments etc.
In general terms though Western Bohemia has been identified by studies like "Solar energy potential in regions of Czech Republic" (Kudela et al., 2019) as having one of the highest potentials within Czechia due to its favorable levels of sunshine duration compared to other parts of country.
