Polysilicon production

Activ Solar produced high-purity polysilicon at its subsidiary PJSC Semiconductor Plant, located in Zaporizhzhia, Ukraine. The production of semiconductor materials at the original Zaporizhzhia 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 Zaporizhzhia Titan and Magnesium Plant in 2002.

The plant was historically 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). In 2011, the facility reached capacity of ~20 metric tons per annum of monocrystalline silicon using legacy equipment with a plan to expand to ~400 metric tons per annum. The factory also produced silicon tetrachloride (SiCl4), hydrogen, nitrogen and hydrochloric acid.

Solar PV projects development

Activ Solar developed large-scale solar photovoltaic installations. As of November 2012, it had developed six solar PV power stations with 313.35 megawatts (MW) of installed capacity on the Crimean Peninsula and Odesa region.

The company constructed Ukraine's first large-scale photovoltaic power plant—the 7.5 MW Rodnikovoye Solar Park—in February 2011. It was built about 3 kilometres (1.9 mi) from Simferopol in Crimea. The total number of solar modules installed reached about 33,800 on a total surface area of approximately 15 hectares (37 acres).

In October 2011, Activ Solar commissioned the 80 MW Okhotnykovo Solar Park. Installation consisting of approximately 360,000 ground-mounted PV-modules and spanning over 160 hectares (400 acres) able to generate 100 GWh of electricity per year.

In December 2011, Activ Solar completed the 105.56 MW Perovo Solar Park, amongst the largest in the world. Perovo's more than 440,000 crystalline solar PV modules can produce as much as 132.5 GWh) of electricity per year.

In April 2012, Activ Solar finished work on the 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 able to generate approximately 40 GWh of electricity per annum.

In July 2012, Activ Solar completed the 42.95 MW Starkozache power plant in Odesa Oblast. It 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 is able to generate 54.106 GWh of electricity per annum.

In November 2012, Activ Solar completed the second phase of the 43.14 MW Dunayskaya Solar Power Station. Located in the southern part of Odesa Oblast, it 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.

In April 2013, Activ Solar announced the commissioning of the 43.4 MW Lymanske Solar Power Plant in the southwestern part of Odesa Oblast. It comprises 181.192 multicrystalline, installed in one row and connected by over 41 inverter stations. The solar plant will generate 59.415 GWh of electricity per annum.

Research and development

Activ Solar owned a research and development joint-venture with Diamond Aircraft Industries. Diamond Activ Solar exhibited a solar aircraft wing at the Paris Air Show 2011.
