Solar PV Analysis of Warsaw, Poland
In Warsaw, Mazovia, Poland, situated at a latitude of 52.2005 and longitude of 20.9236, solar power generation varies across different seasons due to fluctuations in sunlight hours and temperature. During the summer months, the average energy production per day for each kilowatt (kW) of installed solar panels is highest at 5.66 kilowatt-hours (kWh), while winter sees the lowest output at just 0.93 kWh/day. Spring and autumn experience intermediate levels of solar power generation with daily averages of 4.16 kWh/day and 2.29 kWh/day respectively.
The ideal angle for fixed panel installations in this location is a tilt of 43 degrees facing south to maximize exposure to sunlight throughout the year. However, it's important to consider local factors that could potentially impede solar production in Warsaw.
Weather conditions such as cloud cover or rain can have a significant impact on photovoltaic (PV) generation efficiency throughout the year in this region; clouds reduce direct sunlight availability for conversion into energy, while rain may cause dirt or debris accumulation on panels which further decreases their performance.
To ensure greater energy production despite these environmental challenges, preventative measures can be taken during installation such as selecting high-quality PV modules with better low-light performance and incorporating regular maintenance practices like cleaning panels to remove dirt or debris buildup.
Overall, Warsaw's location offers suitable conditions for generating solar power year-round with higher outputs during warmer months when there are longer daylight hours and more intense sunlight available for conversion into electricity by solar panels.
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 Warsaw
Seasonal solar PV output for Latitude: 52.2005, Longitude: 20.9236 (Warsaw, 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 43° South in Warsaw, Poland
To maximize your solar PV system's energy output in Warsaw, Poland (Lat/Long 52.2005, 20.9236) throughout the year, you should tilt your panels at an angle of 43° 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 Warsaw, 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 Warsaw, Poland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 43° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 35° South in Summer | 54° South in Autumn | 65° South in Winter | 44° 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 Warsaw, 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 Warsaw, 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 Warsaw, Poland
The topography around Warsaw, Poland is mostly flat. The city is located on the edge of the Vistula river valley, which has a gently rolling terrain with some low hills and small lakes in the area. Nearby areas that would be most suitable for large-scale solar PV are those with open fields and clear skies, such as agricultural land or grasslands. Areas close to water bodies may also be good locations due to their reflective properties.
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.
