The turnkey projects, which vary between one and 1.2 megawatts in size, were built for both German and Slovak investors. They are located in Poltár, Biskupice and Rumince.
Vario green energy Concept GmbH from Holzgerlingen near Stuttgart and Vario green energy Parks GmbH from Munich worked on the project planning, system configuration and component delivery. Assembly company Draka Service GmbH and an unnamed local grid connection partner also worked on the systems.
Installation time was said to be between six and eight weeks.
According to a statement released, the projects used a total of 70,000 Conergy solar modules, which are expected to generate around seven million kilowatt hours of energy. Under the current feed-in tariffs in the country, they will receive 38.23 euro cents per kilowatt hour.
"In spite of the laborious approval procedure in Slovakia, we are very pleased with the course of the project and the high amount of professionalism shown by all participating parties," commented Axel Fellhauer, managing director of Vario green energy.
Currently Vario green energy has built a total of 7.8 MW worth of photovoltaic plants in Slovakia. However, due to recent tariff changes, it says it will now only concentrate on the rooftop market.
"Since 1 July 2011 the solar electricity funding is limited to roof-top plants with a power of 100 kilowatts maximum," explained Fellhauer.
