Bukhara, Uzbekistan, situated at latitude 39.7686 and longitude 64.4258, presents a varied landscape for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal fluctuations in solar power output, which affects the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
The solar energy potential in Bukhara demonstrates a clear pattern across the four seasons. Summer stands out as the most productive period, with an impressive daily output of 8.16 kWh per kW of installed solar capacity. Spring follows as the second-most productive season, yielding 6.37 kWh/day. Autumn sees a notable decrease to 4.61 kWh/day, while winter experiences the lowest output at 2.66 kWh/day.
These figures indicate that solar energy generation in Bukhara is most effective from late spring through early autumn. During this period, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. However, the substantial drop in winter output suggests that alternative or supplementary energy sources may be necessary during the colder months.
Optimal Panel Positioning
For fixed solar panel installations in Bukhara, the ideal tilt angle to maximize year-round energy production is 34 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 Considerations
While Bukhara's climate is generally favorable for solar energy production, there are some environmental factors to consider:
1. Dust storms: Bukhara's semi-arid climate can lead to occasional dust storms, which may deposit particles on solar panels, reducing their efficiency. Regular cleaning and maintenance of panels is crucial to mitigate this issue.
2. Extreme temperatures: Summer temperatures in Bukhara can soar, potentially affecting the performance of solar panels. Installing panels with good heat dissipation properties and ensuring proper ventilation can help maintain efficiency during hot periods.
To address these challenges, implementing a robust cleaning schedule for the panels and choosing high-quality, heat-resistant PV modules are recommended. Additionally, installing a monitoring system can help quickly identify and address any drops in performance due to environmental factors.
In conclusion, while Bukhara offers good potential for solar energy generation, particularly during the warmer months, careful planning and maintenance are necessary to optimize performance year-round.

Solar output per kW of installed solar PV by season in Bukhara
Seasonal solar PV output for Latitude: 39.7686, Longitude: 64.4258 (Bukhara, 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 Bukhara, Uzbekistan
To maximize your solar PV system's energy output in Bukhara, Uzbekistan (Lat/Long 39.7686, 64.4258) 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 Bukhara, 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 Bukhara, 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 | 54° 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 Bukhara, 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 Bukhara, Uzbekistan.
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 Bukhara, Uzbekistan
The topography around Bukhara, Uzbekistan, is characterized by vast, flat desert plains. This ancient city, located in the southwestern part of the country, sits in the heart of the Kyzylkum Desert, one of Central Asia's largest arid regions. The landscape surrounding Bukhara is predominantly flat, with occasional small hills and sand dunes dotting the horizon. The terrain is mostly composed of sandy and clay soils, typical of desert environments. To the east of Bukhara, the land gradually rises towards the foothills of the Pamir Mountains, but this mountainous terrain is quite distant from the city itself. The immediate vicinity of Bukhara is remarkably level, with very little variation in elevation. This flatness extends for hundreds of kilometers in most directions, creating an expansive and seemingly endless desert panorama. The Zeravshan River, which once flowed near Bukhara, has been largely diverted for irrigation purposes, leaving the area even drier than it naturally would be. The absence of significant water bodies or major geographical features contributes to the uniform, arid nature of the landscape.
Suitability for Large-Scale Solar PV
The topographical characteristics of the region surrounding Bukhara make it highly suitable for large-scale solar photovoltaic (PV) installations. The vast, flat desert plains offer ideal conditions for solar energy production for several reasons: Firstly, the lack of significant elevation changes means that large areas can be easily developed without the need for extensive land preparation or leveling. This flat terrain allows for efficient layout and installation of solar panels over wide areas. Secondly, the desert climate of the region ensures abundant sunshine throughout the year. Bukhara experiences very little cloud cover, with clear skies prevailing for most of the year. This high solar irradiance is crucial for maximizing the energy output of solar PV systems. The areas to the south and west of Bukhara would be particularly well-suited for large-scale solar PV projects. These regions offer expansive, uninterrupted desert landscapes with minimal human settlement or agricultural activity. The absence of competing land uses reduces potential conflicts and simplifies the process of acquiring large tracts of land for solar farms. Additionally, the lack of vegetation in these desert areas means there would be minimal environmental impact in terms of clearing land for solar installations. The natural openness of the landscape also reduces concerns about shading, which can decrease the efficiency of solar panels. However, it's important to note that while the topography is ideal, the harsh desert environment presents challenges such as dust accumulation on solar panels and the need for water for cleaning and maintenance. Despite these challenges, the overall topographical and climatic conditions make the areas around Bukhara highly promising for large-scale solar PV development, offering significant potential for renewable energy production in Uzbekistan.Uzbekistan solar PV Stats as a country
