PJSC Semiconductor Plant
Activ Solar LLC (Ukraine)
Activ Solar GmbH, headquarterd in Vienna, Austria is engaged in the production of polycrystalline silicon (polysilicon) for the solar PV industry and the development of large-scale photovoltaic power stations. The company is a member of the European Photovoltaic Industry Association.
Activ Solar maintains offices in Vienna and Wiener Neustadt in Austria, and in Kiev, Zaporizhia, Simferopol and Odessa in Ukraine.
Polysilicon production 
Activ Solar produces high-purity polysilicon at its subsidiary PJSC Semiconductor Plant, located in Zaporizhia, Ukraine. The production of semiconductor materials at the original Zaporizhia Titan and Magnesium Plant dates back to 1935. The facility formed the foundation of PJSC Semiconductor Plant, which began production of semiconductor-grade polysilicon in 1964. It was separated from the Zaporizhia Titan and Magnesium Plant in 2002.
The plant historically was also the only manufacturer of high-purity trichlorosilane in the Soviet Union. After comprehensive refurbishment and modernization, PJSC Semiconductor Plant reached an annual capacity of 2,500 metric tons of polysilicon and 27,000 metric tons of trichlorosilane (HCl3Si). The facility produces ~20 metric tons per annum of monosilicon using legacy equipment with a plan to expand to ~400 metric tons per annum. The factory also produces silicon tetrachloride (SiCl4), hydrogen, nitrogen and hydrochloric acid.
Solar PV project development 
Activ Solar develops, finances and realizes large-scale solar photovoltaic installations. As of November 2012, it has developed six solar PV power stations with 313.35 MW of installed capacity on the Crimean Peninsula and Odessa region. The company constructed Ukraine's first large-scale Photovoltaic power plant 7.5 MW Rodnikovoye Solar Park in February 2011. The power plant is built near the town of Rodnikovoye, about 3 kilometres (1.9 mi) away from Simferopol, the capital of the Autonomous Republic of Crimea. The total number of solar modules installed reach about 33,800 on a total surface area of approximately 15 hectares (37 acres).
In October 2011, Activ Solar commissioned one of the world's largest solar power stations, the 80 MW Okhotnykovo Solar Park. Installation consisting of approximately 360,000 ground-mounted PV-modules and spanning over 160 hectares (400 acres) generates 100 GWh of electricity per year enough to meet the energy needs of about 20,000 households.
In December 2011, Activ Solar has completed its third ground-breaking project, the 105.56 MW Perovo Solar Park, amongst the largest in the world. Built in record-setting time, Perovo's more than 440,000 crystalline solar PV modules can produce as much as 132.5 GWh) of electricity per year, enough to meet the needs of Simferopol. More than 105,000 tons of carbon dioxide emissions will be avoided.
In April 2012, Activ Solar finished work on its fourth large-scale project completed to date, 31.55 MW station located in the village of Mityaevo in Crimea. The ground-mounted power station houses over 134,000 polycrystalline modules, installed in double rows and connected by over 440 kilometres (270 mi) of cable, and generates approximately 40 GWh of electricity per annum enough to supply 8,000 households.
In July 2012, Activ Solar completed 42.95 MW Starkozache power, the first photovoltaic project completed by Activ Solar in Odessa Oblast. The Starokozache Power Station is installed over a surface of 80 hectares (200 acres) and consists of 185,952 multi-crystalline solar modules and 41 inverters. The solar plant will generate 54.106 GWh of electricity per annum, enough to supply approximately 11,000 households and saves up to 44,000 tons of CO2 emissions per year.
In November 2012, Activ Solar completed the second and final phase of its sixth large-scale solar installation—43.14 MW Dunayskaya Solar Power Station in Odessa Oblast. Located in the southern part of Odessa Oblast, the solar power plant comprises 182,380 multicrystalline photovoltaic modules, 40 inverter stations and around 645 kilometres (401 mi) of cable.
In February 2013, Activ Solar announced the start of commissioning of the 29.3 MW Voznesensk Solar Power Station in Mykolaiv region. Voznesensk Solar Power Station consists of 121,176 multicrystalline solar modules and 27 inverter stations installed on a four-row mounting system. The power station's electricity production capacity totals 35,000 megawatt hours per annum and will save over 28,000 tons of CO2 per annum.
Research and development 
Activ Solar owns a research and development joint-venture with Diamond Aircraft Industries with an aim to develop products and applications for the photovoltaic industry. Diamond Activ Solar exhibited a solar aircraft wing at the Paris Air Show 2011 Le Bourget.
Awards and recognitions 
In February 2011, Rodnikovoye Solar Park has been recognized as one of the winners for the “Best Project in the Field of Renewable Energy” by Top-100. Energy Efficiency Award 2011, organized and conducted by the State Agency on Energy Efficiency and Energy Saving of Ukraine (SAEE).
In December 2011, 82.65 MWp Ohotnikovo Solar Power Station has been recognized as the "Best project in the field of Renewable Energy" by Green Awards Ukraine, contest where the jury is presented by the leading experts in the field of environmental technologies and practices of the European level, public opinion leaders and representatives of influential international organizations and institutions.
According to the company register, Activ Solar is formally 100% owned by Liechtenstein-registered P&A Corporate Trust. According to Ukrainska Pravda, Ukrainian opposition media, and its affiliated economic newsletter Ekonomichna Pravda, according to a British register, P&A Corporate Trust owns British firm Blythe (Europe) Ltd, which owns 35% of company Tantalit which is the nominal owner of the residence of President Viktor Yanukovych at Mezhyhirya.
According to other Ukrainian sources, Activ Solar is controlled by Ukraine's former first deputy prime minister Andriy Klyuyev and his brother Serhiy Klyuyev. CEO of Activ Solar, Kaveh Ertefai, is Serhiy Klyuyev's son-in-law. Bogdan Klyuyev, son of Andriy Klyuyev, is a business developer manager of Activ Solar LLC (Ukraine). According to Kyiv Post, Klyuyev's companies are registered at the same building where Activ Solar has its representative office in Ukraine.
According to the report by Ukrayinska Pravda, Solar Activ was founded by Slav Beteiligung GmbH, owned by Slav AG, investment firm of by brothers Kluyevs. In late 2008, the ownership was transferred to Kaveh Ertefay. In July 2009, ownership was transferred to P&A Corporate Trust.
