Guliston, Sirdaryo Region, Uzbekistan shows significant seasonal variation in solar energy production potential, making it a moderately suitable location for year-round solar PV generation in the Northern Temperate Zone.

Seasonal Solar Performance

The location experiences strong summer performance with 8.34 kWh per day per kW of installed capacity, making this the prime solar generation period. Spring also offers good production at 6.01 kWh per day per kW, providing another favorable season for energy generation. Autumn production drops to 4.38 kWh per day per kW, while winter shows the lowest output at just 2.43 kWh per day per kW. This represents more than a three-fold difference between peak summer and winter production, which is typical for locations at this latitude. For fixed panel installations at Guliston, Sirdaryo Region, the optimal tilt angle is 34 degrees facing south to maximize total year-round solar output. This angle balances seasonal sun angles throughout the year for optimal energy capture.

Local Environmental Factors

Several environmental and weather factors in Guliston could potentially impact solar energy production:

• Dust accumulation from the arid Central Asian climate can reduce panel efficiency
• Occasional sandstorms common to the region may coat panels with fine particles
• Temperature extremes, particularly hot summers, can reduce panel efficiency
• Potential for snow coverage during winter months

Preventative Installation Measures

To optimize solar production at this location, several installation strategies should be considered. Regular cleaning schedules are essential due to dust accumulation, with automated cleaning systems being particularly beneficial in this arid environment. Installing panels with adequate ventilation underneath helps manage the efficiency losses from high summer temperatures. The 34-degree tilt angle also assists with natural cleaning from precipitation and helps snow slide off more easily during winter months. Choosing panels with anti-soiling coatings can reduce dust adhesion, while robust mounting systems should account for potential wind loads from regional storms. These measures help ensure consistent energy production despite local environmental challenges.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

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

Seasonal solar PV output for Latitude: 40.4906, Longitude: 68.791 (Guliston, Uzbekistan), 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 34° South in Guliston, Uzbekistan

To maximize your solar PV system's energy output in Guliston, Uzbekistan (Lat/Long 40.4906, 68.791) throughout the year, you should tilt your panels at an angle of 34° 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 Guliston, Uzbekistan

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 Guliston, Uzbekistan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
24° South in Summer	44° South in Autumn	55° South in Winter	32° 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 Guliston, Uzbekistan

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 Guliston, Uzbekistan.

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 Guliston, Uzbekistan

Topographical Features Around Guliston

Guliston sits in the fertile Fergana Valley region of eastern Uzbekistan, positioned at an elevation of approximately 400 meters above sea level. The surrounding landscape is characterized by relatively flat to gently rolling terrain, typical of this productive agricultural basin. The city lies within the broader Syr Darya river system, which has created extensive alluvial plains over millennia through sediment deposition. The immediate vicinity of Guliston features predominantly level ground with minimal elevation changes, making it part of the expansive lowlands that define much of the Fergana Valley floor. To the north and east, the terrain gradually transitions into slightly more undulating countryside, while the western approaches remain largely flat. The area benefits from rich, deep soils that have been shaped by centuries of river activity and agricultural cultivation.

Regional Geological Context

The broader regional topography shows the Fergana Valley enclosed by mountain ranges on multiple sides. The Tian Shan mountains rise to the north and northeast, while the Pamir-Alay range forms boundaries to the south and southeast. However, these mountainous areas lie at considerable distances from Guliston itself, leaving the immediate surroundings relatively unaffected by dramatic topographical variations. The valley floor where Guliston is located represents some of the most geologically stable and accessible terrain in the region. Seasonal flooding patterns have historically shaped the landscape, creating natural drainage channels and depositing fertile sediments across wide areas. This geological history has resulted in expansive flat zones with excellent load-bearing capacity for infrastructure development.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for extensive solar photovoltaic installations would be found in the flat agricultural areas extending westward and southward from Guliston. These zones offer several key advantages including minimal grading requirements, excellent accessibility for construction equipment, and proximity to existing electrical infrastructure. The level terrain eliminates concerns about shading between panel rows and reduces overall installation complexity. Areas to the southwest of the city present particularly favorable conditions, where large tracts of relatively unused or marginally productive land could accommodate substantial solar farms without competing directly with prime agricultural zones. The stable geological conditions throughout this region provide excellent foundations for mounting systems and supporting infrastructure. The flat expanses north of Guliston also merit consideration, though careful evaluation of soil conditions and drainage patterns would be essential in these areas that may experience seasonal moisture variations. The consistent elevation and minimal slope variations across these northern zones would facilitate efficient panel layout and maintenance access. Transportation infrastructure accessibility represents another crucial factor favoring locations along the existing road networks radiating outward from Guliston. Areas within reasonable proximity to transmission lines and substations would offer additional economic advantages for large-scale solar development projects.
