The location of Irshava, Zakarpattia Oblast, Ukraine, situated at latitude 48.3187 and longitude 23.0393, presents a mixed picture for solar energy generation throughout the year. This Northern Temperate Zone location experiences significant seasonal variations in solar energy production, which impact the overall efficiency of solar PV systems.

Seasonal Solar Energy Production

Summer stands out as the most productive season for solar energy in Irshava, Zakarpattia Oblast, with an impressive output of 6.09 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second-best season, generating 4.34 kWh/day/kW. However, the colder months see a substantial drop in energy production, with autumn yielding 2.86 kWh/day/kW and winter plummeting to a mere 1.14 kWh/day/kW.

These figures highlight the stark contrast between the warm and cold seasons, with summer producing more than five times the energy of winter. This variation underscores the importance of efficient energy storage solutions to balance out the seasonal disparities.

Optimal Panel Tilt Angle

For fixed panel installations in Irshava, Zakarpattia Oblast, the ideal tilt angle to maximize year-round solar production is 41 degrees facing South. This angle is calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the Earth's elliptical orbit and the location's specific latitude.

Environmental and Weather Considerations

While Irshava's location is generally favorable for solar energy production, there are some environmental factors to consider:

• Snow accumulation in winter can significantly reduce panel efficiency
• Frequent cloud cover, especially in autumn and winter, may impact energy generation

To mitigate these issues, installers should consider using panels with anti-soiling coatings to reduce snow adhesion and implementing a regular cleaning schedule. Additionally, choosing high-efficiency panels that perform well in low-light conditions can help maintain energy production during cloudy periods.

In conclusion, while Irshava's location presents challenges for year-round solar energy production, particularly in winter, the strong performance during summer and spring makes it a viable option for solar PV systems. With proper planning and mitigation strategies, solar energy can be a valuable contributor to the local energy mix.

Solar output per kW of installed solar PV by season in Irshava

Seasonal solar PV output for Latitude: 48.3187, Longitude: 23.0393 (Irshava, 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 Irshava, Ukraine

To maximize your solar PV system's energy output in Irshava, Ukraine (Lat/Long 48.3187, 23.0393) 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 Irshava, 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 Irshava, 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
32° South in Summer	52° South in Autumn	62° 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 Irshava, 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 Irshava, Ukraine.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Irshava, Ukraine

The topography around Irshava, Ukraine, is characterized by a picturesque blend of rolling hills, verdant valleys, and forested areas. Situated in the southwestern part of the Zakarpattia Oblast, Irshava is nestled in the foothills of the Carpathian Mountains. The terrain gradually rises from the town towards the northeast, where the landscape becomes more mountainous and rugged. To the south and west of Irshava, the land is generally flatter, consisting of gentle slopes and open fields. This area is part of the Transcarpathian Lowland, which extends towards the Hungarian border. The Irshava River, a tributary of the Borzhava River, flows through the region, carving a shallow valley and creating fertile floodplains along its course.

Potential Areas for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Irshava, the most suitable areas would likely be found in the flatter, more open terrain to the south and west of the town. These regions offer several advantages for solar energy development: Firstly, the relatively level ground in the lowland areas would require less site preparation and earthwork, reducing construction costs and environmental impact. The open fields also provide ample space for large arrays of solar panels without the need for extensive deforestation. Secondly, these areas generally receive more direct sunlight throughout the day compared to the hilly and mountainous regions to the northeast. The absence of significant geographical features that could cast shadows on the panels ensures optimal solar exposure. Lastly, the proximity to existing infrastructure, such as roads and power lines, in the more developed lowland areas could facilitate easier construction and grid connection for solar farms. However, it's important to note that any large-scale solar PV project would require detailed site-specific assessments, including solar irradiance studies, environmental impact evaluations, and consideration of local land use regulations. The agricultural importance of the lowland areas would also need to be taken into account to balance energy production with food security concerns.
