Solar PV Analysis of Drohobych, Ukraine
In Drohobych, Lviv, Ukraine, located at latitude 49.3587 and longitude 23.5185, the average solar energy generated varies significantly with the seasons. During the summer season, each kilowatt of installed solar capacity can generate an impressive average of 5.82 kilowatt-hours per day due to longer daylight hours and higher sun intensity. In contrast, during winter when daylight is limited in this Northern Temperate Zone location, solar power generation drops considerably to an average of just 1.08 kilowatt-hours per day per installed kilowatt.
The transitional seasons of spring and autumn also reflect this variation in sunlight availability: spring sees a robust average production rate of 4.20kWh/day per kW while autumn's shorter days result in a lower yield averaging around 2.66kWh/day per kW.
This geographical location necessitates that for fixed panel installations (excluding tracking systems), panels should ideally be tilted at an angle of approximately 41 degrees towards the south to optimise exposure to sunlight throughout the year.
However, it's important to note that Drohobych's local environmental conditions can pose certain challenges for optimal solar power generation - heavy snowfall during winter can obscure panels reducing their output significantly; strong winds could potentially damage installations or cause misalignment affecting efficiency.
To mitigate these issues and ensure greater energy production throughout the year despite these challenges:
1) Regular maintenance including prompt snow removal from panels during winter months is crucial.
2) Installing durable mounting systems designed to withstand high wind speeds will help protect against potential wind damage or misalignment.
Despite these considerations, overall Drohobych offers a favourable environment for generating substantial amounts of solar power annually thanks largely due its seasonal variations in sunlight availability which are well suited for harnessing with appropriately angled fixed panel installations.
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 Drohobych
Seasonal solar PV output for Latitude: 49.3587, Longitude: 23.5185 (Drohobych, 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 Drohobych, Ukraine
To maximize your solar PV system's energy output in Drohobych, Ukraine (Lat/Long 49.3587, 23.5185) 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 Drohobych, 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 Drohobych, 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 Drohobych, 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 Drohobych, 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 Drohobych, Ukraine
The topography around Drohobych, Ukraine is mostly flat and low-lying. There are some hills to the east and south of the city, but nothing too steep or mountainous. The best areas for large-scale solar PV would be on the flat plains in the north and west of Drohobych, as these will receive a lot of direct sunlight throughout the day.
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.
