Onsite tests were performed according to IEC 61724: Photovoltaic System Performance Monitoring
and the seven-day weighted average was 80.39%
According to the PV system report submitted to the supervisor for review
The actual PR is 3.8% higher than simulated
How did this PV plant exceed expectations so dramatically? The project uses Risen Energy 330 W polycrystalline PV modules, Huawei SUN2000-185KTL string inverters, and Arctech Solar Skyline 1V84 trackers
The string inverters work with the trackers
and the PV modules move by tracking the sun
ensuring the optimal status of each PV string in the plant
The project owner said Huawei's string inverters provided outstanding performance in ensuring the efficient and reliable operation of the plant
Huawei inverter's multi-MPPT feature can help minimize the impact of PV string mismatch during dusty and cloudy weather
A 3.5 MW PV array supports 170 MPPT routes to ensure that each PV string works at its optimum
but Huawei SUN2000 series string inverters can operate over a wide temperature range
which is befitting to environments with both extremes of hot and cold such as Kazakhstan
They can run stably in the temperature range of –40°C to 60°C
with the availability reaching over 99.996%
Extremely hot or cold conditions would usually pose severe challenges on components
Huawei employs high component selection standards and patented heat dissipation technologies to ensure the reliability of all components
Huawei string inverters use low power consumption control technology
power supply technology with a wide input voltage range
and power component shutdown peak suppression technology
They also support an operating voltage range as wide as 500–1500 V
A lower operating voltage lower limit enables inverters to start early and shut down late every day
which allows them to generate more electricity
The success of this project is inseparable from the meticulous design and optimization of Risen Energy’s Overseas Project Technical Team based in China
was on site personally for inspection and research
the technical team of Risen Energy compares more than 100 system design solutions with automatic configuration and loss algorithms
and analyzes the cost and benefit sensitivity
The team optimizes and selects the cost structure of each project
and capable solution design ensures a balance in project cost and quality
The corresponding balance created between cost and energy yield is the key to the high energy yield of the project
According to data from the Ministry of Energy of Kazakhstan
the country generated 548.4 million kWh of electricity using renewable energy
In the Concept of Transition towards Green Economy
the Kazakhstan government proposed to increase the proportion of electricity generated from renewable energy to 3% by 2020
We believe that more PV plants with unexpected PR will make the future of Kazakhstan's PV market landscape brighter
After years of making big promises to invest in solar
Kazakhstan and Uzbekistan are now competing to open the largest solar fields in Central Asia and China gunning for a big role in these fast-growing solar markets
Kazakhstan has experimented with solar since 2012
when then-President Nursultan Nazarbayev inaugurated a small plant to produce photovoltaic cells in Astana
Eurasianet says that according to a UN estimate
Kazakhstan has over 85 percent of Central Asia’s total solar potential
Yet Nazarbayev’s ambition has been slow to meet reality: Four years later
Kazakhstan had only a modest 157 MW of installed solar capacity
State capitalism in China then offered Kazakhstan a nudge. By 2017
as China’s domestic solar capacity was outstripping demand
Beijing reportedly reined in its liberal aid for producers and instructed them to seek business abroad
China offered Kazakhstan a taste of its technologies
gifting a 1 MW solar plant to the Alatau Innovation Park near Almaty. In June 2018
Ningbo-based Risen Energy began work on a $39 million 40 MW solar photovoltaic plant in Karaganda
The European Bank for Reconstruction and Development (EBRD) reportedly loaned US$22 million toward the plant in Karaganda. A few months later
the EBRD loaned another US$42.5 million toward a US$75 million 63 MW solar photovoltaic power plant that Risen is building in Chulakkurgan
which now produces 70 percent of the world’s solar panels
is well represented in Kazakhstan’s new renewable projects
Astana was predicting installed solar capacity by the end of 2020 to reach 714 MW
A government report last month said solar capacity had reached 467 MW
Renewables are still small fry in Kazakhstan
solar reportedly accounts for 56 percent of the country’s total renewable capacity. Renewables overall
contribute just 3 percent of all power produced in Kazakhstan
the vast majority of which is still made by burning coal
Uzbekenergo (Uzbekistan’s state-run energy monopoly) briefly dallied with solar energy
before pushing away suitors and only recently announcing another go
the Asian Development Bank (ADB) approved a $100 million loan toward a 100 MW solar farm in Samarkand
But then the Uzbek government reportedly got nervous. It had trouble securing a contractor – owing both to a lack of Uzbek expertise in solar and lack of firms willing to work in what was then an isolated state with stringent capital controls
when Uzbekenergo finally sealed a deal with Shandong-based China Shuifa Singyes Energy Holdings
ADB even negotiated for the company to operate and maintain the solar plant for three years after commissioning
the new government in Tashkent called off the project
explaining to the ADB that Uzbekistan did not have the technical capacity to run the plant
The government also argued that 100 MW was too ambitious for a first foray into solar.
Tashkent reportedly changed its mind again; in August
it submitted a proposal for a solar project of the same size in the same city
but this time to the EBRD. China Shuifa Singyes is out
Uzbekenergo is now working with France’s Total Eren. Industry insiders believe Total is now lobbying the EBRD to finance the project
