Solar PV Analysis of Brenna, Poland
The location at Brenna, Silesia, Poland is moderately suitable for generating energy through solar PV panels all year round. However, the productivity of these panels varies significantly with each season due to changes in daylight hours and sun intensity.
In Summer, you can expect the highest energy production with an average of 5.84kWh per day for every kilowatt of installed solar. This is because during Summer days are longer and the sun shines more intensely. Spring also offers decent productivity with around 3.99kWh/day per kW of installed solar.
On the other hand, Autumn and Winter see a significant drop in energy production due to shorter days and less intense sunlight. In Autumn, you can expect around 2.67kWh/day per kW of installed solar while Winter offers only about 1.16kWh/day per kW.
To maximize total year-round production from your solar PV system at this location, it's recommended to tilt your panels at an angle of 42 degrees towards the South.
As for potential factors that could hinder your solar panel's productivity in Brenna; weather conditions like heavy snowfall during winter could cover your panels thus reducing their efficiency or even causing damage to them if not properly managed; foggy conditions might also reduce sunlight intensity hence lower output from the panels; and tall trees or buildings nearby could cast shadows on your installation thereby affecting its performance.
To counter these issues:
1) Regular maintenance should be performed especially during winter to remove any snow covering.
2) If foggy conditions are frequent then consider installing more efficient types of solar cells that perform better under low light conditions.
3) Before installation ensure there are no obstructions like tall trees or buildings nearby that might cause shading on your system throughout the day.
4) Lastly, use sturdy materials capable of withstanding harsh weather conditions for long-term durability and efficiency.
So overall while Brenna isn't an ideal spot for year-round solar energy production due to its seasonal variations and potential weather challenges, with the right setup and regular maintenance it can certainly be a viable option.
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 150 locations across Poland. 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 Brenna
Seasonal solar PV output for Latitude: 49.7327, Longitude: 18.9086 (Brenna, Poland), 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 Brenna, Poland
To maximize your solar PV system's energy output in Brenna, Poland (Lat/Long 49.7327, 18.9086) 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 Brenna, Poland
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 Brenna, Poland. 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 Brenna, Poland
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 Brenna, Poland.
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 Brenna, Poland
Brenna, Poland is located in the Silesian Voivodeship in southern Poland. The topography of this region is characterized by mountainous terrain, being part of the Beskids mountain range, specifically the Silesian Beskids. The area features valleys and forests with numerous rivers and streams.
When considering large-scale solar PV installations, flat or gently sloping terrains are typically preferred as they require less groundwork to prepare for installation. Additionally, these locations should ideally have a high level of solar irradiance (sunlight exposure) and minimal shading from nearby structures or vegetation.
Given Brenna's mountainous topography, it may not be ideal for large-scale ground-mounted solar PV systems due to the steep slopes and potential shading from mountains. However, there could still be opportunities for smaller scale rooftop installations on buildings within the town itself or on south-facing slopes that receive good sunlight exposure throughout the day.
For larger scale projects, areas with flatter terrain would be more suitable. These could potentially be found towards the north of Brenna where the land begins to flatten out into plains around cities like Częstochowa and Katowice.
However, any decision regarding installation should also take into account other factors such as local climate conditions (including cloud cover), proximity to electrical grid infrastructure for power distribution and local planning regulations among others. A detailed site survey would typically be carried out before any final decisions are made.
Poland solar PV Stats as a country
Poland ranks 20th in the world for cumulative solar PV capacity, with 6,257 total MW's of solar PV installed. Each year Poland is generating 165 Watts from solar PV per capita (Poland ranks 32nd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Poland?
Yes, there are incentives for businesses wanting to install solar energy in Poland. The Polish government offers a number of financial incentives and tax breaks for businesses that invest in renewable energy sources such as solar power. These include grants, subsidies, and tax credits. Additionally, the government has set up a system of feed-in tariffs which guarantee a certain price per kilowatt hour (kWh) of electricity generated from renewable sources such as solar power. This helps to make investing in solar energy more attractive to businesses by providing them with a guaranteed return on their investment.
