Solar PV Analysis of Stryi, Ukraine
The location in Stryi, Lviv, Ukraine, situated at coordinates 49.2672, 23.8474, presents a mixed scenario for solar PV energy generation throughout the year. This Northern Temperate Zone location experiences significant seasonal variations in solar energy production, which impacts the overall efficiency of solar installations.
Seasonal Solar Energy Production
Solar energy generation in Stryi follows a predictable pattern aligned with the changing seasons. Summer stands out as the most productive period, with an impressive daily output of 5.82 kWh per kW of installed solar capacity. Spring follows as the second most productive season, yielding 4.20 kWh per day. Autumn sees a considerable drop in production to 2.66 kWh per day, while winter experiences the lowest output at just 1.08 kWh per day.
Optimal Times for Solar Generation
The most favorable months for solar energy production in Stryi are from late spring through early autumn, roughly spanning May to September. During this period, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. Conversely, the winter months from November to February present significant challenges due to shorter days and lower sun angles, resulting in substantially reduced energy output.
Panel Installation Considerations
To maximize year-round solar energy production in Stryi, Lviv, fixed solar panels should be installed at a tilt angle of 41 degrees facing south. This optimal angle helps balance energy capture across seasons, enhancing overall annual efficiency.
Environmental and Weather Factors
Several environmental and weather factors can impact solar energy production in Stryi:
- Snow accumulation in winter can significantly reduce panel efficiency.
- Frequent cloud cover, particularly during autumn and winter, may limit solar exposure.
To mitigate these challenges, 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 panel cleaning and maintenance are also crucial to ensure optimal performance year-round.
While Stryi's location presents some challenges for consistent year-round solar energy production, proper installation techniques and maintenance can help maximize the potential of solar PV systems in this area.
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 66 locations across Ukraine. 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 Stryi
Seasonal solar PV output for Latitude: 49.2672, Longitude: 23.8474 (Stryi, Ukraine), 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 Stryi, Ukraine
To maximize your solar PV system's energy output in Stryi, Ukraine (Lat/Long 49.2672, 23.8474) 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 Stryi, Ukraine
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 Stryi, Ukraine. 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 |
|---|---|---|---|
| 33° South in Summer | 53° South in Autumn | 63° 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 Stryi, Ukraine
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 Stryi, Ukraine.
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 Stryi, Ukraine
The area around Stryi, Ukraine, is characterized by a diverse and interesting topography. Stryi is located in the western part of Ukraine, in the Lviv Oblast region. The city itself sits in a valley along the Stryi River, which is a tributary of the larger Dniester River.
The surrounding landscape is a mix of gentle hills and flat plains, typical of the Carpathian Foothills. To the south and southwest of Stryi, the terrain becomes more rugged as it transitions into the Carpathian Mountains. These mountains, while not extremely high in this area, create a picturesque backdrop and influence the local climate.
To the north and east of Stryi, the land flattens out into what's known as the Dniester Plain. This area is characterized by rolling hills and wide, open spaces. The soil in this region is generally fertile, making it suitable for agriculture.
When considering areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, the flatter regions to the north and east of Stryi would likely be the best candidates. These areas offer several advantages for solar energy production:
- The relatively flat terrain makes construction and maintenance of solar panels easier and more cost-effective.
- There are fewer natural obstacles that could cast shadows on the panels, maximizing sun exposure throughout the day.
- The open spaces in the Dniester Plain provide ample room for large-scale installations without significant land use conflicts.
However, it's important to note that while the topography in these areas is favorable, other factors such as local climate, grid connectivity, and land ownership would also need to be considered when planning a large-scale solar PV project. Additionally, care should be taken to balance energy production needs with preserving the region's agricultural capacity, as the fertile soil in this area is a valuable resource for food production.
Ukraine solar PV Stats as a country
Ukraine ranks 15th in the world for cumulative solar PV capacity, with 8,062 total MW's of solar PV installed. This means that 5.00% of Ukraine's total energy as a country comes from solar PV (that's 15th in the world). Each year Ukraine is generating 183 Watts from solar PV per capita (Ukraine ranks 27th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Ukraine?
Yes, there are incentives for businesses wanting to install solar energy in Ukraine. The Ukrainian government has implemented a number of policies and programs to encourage the adoption of renewable energy sources, including solar energy. These include tax exemptions, grants, and subsidies for businesses that install solar systems. Additionally, the government has established a feed-in tariff program which guarantees a fixed price for electricity generated from renewable sources such as solar power.
