Solar PV Analysis of Tashkent, Uzbekistan
Tashkent, Uzbekistan, with its geographical coordinates of 41.2615 latitude and 69.2177 longitude, presents a favorable environment for solar photovoltaic (PV) power generation due to the substantial average daily kilowatt-hours (kWh) per kilowatt (kW) of installed solar capacity throughout the year. During summer, Tashkent's longer daylight hours result in an impressive average of 8.32 kWh/day per kW of installed solar. Spring follows suit with a commendable output of 6.02 kWh/day per kW while autumn yields an average of 4.38 kWh/day per kW due to shorter daylight hours but still ample sunshine. In winter, despite the shortest days, there is a satisfactory production level of approximately 2.46 kWh/day per kW.
The optimal tilt angle for fixed solar panels in Tashkent is towards the South at an inclination of about 35 degrees which maximizes exposure to sunlight and enhances energy generation efficiency.
While Tashkent provides a suitable environment for harnessing solar energy consistently throughout the year, it's worth considering potential local factors that may affect energy production levels slightly such as occasional high wind speeds or heavy rainfall events which could obscure sunlight temporarily and reduce PV system performance marginally.
However these environmental conditions are not prevalent in this region and should have minimal impact on annual overall production levels from PV systems installed here.
To mitigate any potential reduction in energy yield due to these weather conditions when installing solar panels in Tashkent; it would be prudent to position them in areas less exposed to strong winds or heavy rainfalls where possible; also selecting robust panel designs that can withstand such adverse weather conditions without significant loss in performance will ensure greater consistency and reliability in your clean energy generation efforts here.
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 8 locations across Uzbekistan. 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 Tashkent
Seasonal solar PV output for Latitude: 41.2615, Longitude: 69.2177 (Tashkent, 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 35° South in Tashkent, Uzbekistan
To maximize your solar PV system's energy output in Tashkent, Uzbekistan (Lat/Long 41.2615, 69.2177) throughout the year, you should tilt your panels at an angle of 35° 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 Tashkent, 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 Tashkent, Uzbekistan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 25° South in Summer | 45° South in Autumn | 56° South in Winter | 33° 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 Tashkent, 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 Tashkent, 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 Tashkent, Uzbekistan
The topography around Tashkent, Uzbekistan is mostly flat and consists of large steppes. Areas to the south-west of the city are best suited for large-scale solar PV installations due to their high levels of sunlight and low cloud cover. The flat terrain also makes installation easier as it does not require any special engineering or construction. Additionally, these areas have access to good infrastructure such as roads and power lines, which can be used to connect the solar panels to the grid.
Uzbekistan solar PV Stats as a country
Uzbekistan ranks 86th in the world for cumulative solar PV capacity, with 104 total MW's of solar PV installed. Each year Uzbekistan is generating 3 Watts from solar PV per capita (Uzbekistan ranks 82nd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Uzbekistan?
Yes, there are incentives for businesses wanting to install solar energy in Uzbekistan. The government has implemented a number of policies and programs to encourage the adoption of renewable energy sources such as solar power. These include tax exemptions, subsidies, and other financial incentives for businesses that invest in solar energy projects. Additionally, the government has established a Renewable Energy Fund which provides grants and loans to support renewable energy projects.
