Next week, Brasov-based RaRa Parc company will be put into service the biggest solar farm in Romania, with an output of 8.75 MW, Mediafax notes. The power that will be produced by the Isaccea Photovoltaic Station will meet the demand of a total of 4,000 households. The project general contractor is German company Gehrlicher Solar. Ra-Ra Parc is owned by three individual persons – Emil Morariu (40%), Doru Alin Plopeanu and Razvan-Constantin Neamtu (30% each). Photovoltaic panels with a combined output of 13.1 MW are currently installed in Romania and new units of almost 100 MW will be set up next year. One such new photovoltaic farm with an installed output of 12 MW will begin to produce electricity in the very first days of 2013 in Mehedinti, being the result of an investment of EUR 16.5 M. Companies tend to invest these days in photovoltaic installations because of the support the state offers through the green certificate system. The green certificates are granted free of charge to renewable energy producers who, in their turn, sell them on to suppliers who are supposed to purchase them up to annual quotas under the law. Renewable energy producers gain twice – first from selling the power they generate and second from selling green certificates. The purchasing cost of the green certificates is transferred on to suppliers in the invoices made out to final users.
