Today, the Bulgarian company Sunservice Ltd. is commissioning its first photovoltaic power plant fitted with SolarMax inverters in the western Bulgarian town of Ihtiman . The system delivers an output of 2 megawatts. Beside amorphous silicon modules the Sofia based company has also installed six central inverters of the type SolarMax 330C-SV. The devices each have a rated output of 330 kilowatts and achieve a maximum efficiency of 98 percent.

When selecting the inverters, the head of Sunservice, Rumen Christov, attached great importance to high quality and know-how. “Sputnik has a lot of experience with central inverters,” says Christov. He expects the solar plant to produce 1,250 kilowatt hours per kilowatt annually. Based on the present Bulgarian infeed rate for power, the plant operator will be paid 37.2 euro cents for every kilowatt hour produced.

Because of the good irradiation conditions and the attractive price, Christov expects rapid growth in the Bulgarian solar market. “At present, in Bulgaria , less than 10 megawatts of photovoltaic capacity is installed,“ says Christov. “This year, new plants with an overall capacity of 10 to 50 megawatts will be built. By 2015, in Bulgaria , plants will be producing a total output of 500 to 1,000 megawatts of solar power. By 2020 this figure will rise to 2.5 to 4 gigawatts.“

Sputnik’s head of sales and marketing, Daniel Freudiger, is looking forward to more projects in this Balkan country: “ Bulgaria is a very important growth market for us. We have already signed several excellent partnerships and will continuously expand our network.” This past March, for example, in eastern Bulgaria the Swiss inverter manufacturer commissioned the country’s largest solar plant with an overall capacity of 2.4 megawatts fitted with SolarMax central inverters.

About Sputnik Engineering AG

Sputnik Engineering AG, a Swiss company, is one of the world’s leading manufacturers of grid-connected solar inverters. Under the name SolarMax the company develops, produces and sells inverters for every facility – from photovoltaic systems on single-family homes whose kilowatt output is modest, to the solar power plants whose output is measured in megawatts. The inverter is a key component of the solar plant, transforming the generated direct current into grid-compliant alternating current. Superior efficiency and long service life are the hallmarks of SolarMax products, whose technology is always state of the art, because of their reliable Swiss quality.

Today, Sputnik Engineering has a staff of 330 at its Swiss corporate headquarters and its subsidiaries in Neuhausen (Germany ), Madrid (Spain ), Milan (Italy ) and Saint Priest (France) and at their branch locations in Brussels and Prague .
