Solar power in Romania has an installed capacity of 740.4 MW as of 2013 a 15 fold increase from 2012. The country had in 2007 an installed capacity of 0.30 MWp, which increased to 3.5 MW by the end of 2011, and to 6.5 MW by the end of 2012. Romania is located in an area with a good solar potential of 210 sunny days per year and with an annual solar energy flux between 1,000 kWh/ m2/year and 1,300 kWh/ m2/year. From this total amount around 600 to 800 kWh/ m2/year is technically feasible. The most important solar regions of Romania are the Black Sea coast, Dobrogea and Oltenia with an average of 1,600 kWh/ m2/year.
Romania was a major player in the solar power industry, installing in the 1970s and '80s around 800,000 square metres (8,600,000 sq ft) of low quality solar collectors that placed the country third worldwide in the total surface area of PV cells. One of the most important solar projects was the installation of a 30 kW solar panel on the roof of the Politehnica University of Bucharest that is capable of producing 60 MWh of electricity per year.
Rominterm, a Romanian company, by 2010, installed a total of 600 solar panels in Mangalia, Constanţa County making the city self-sufficient in terms of heated water during the summer months and providing around 70% of heated water in the winter months and another 1,150 solar panels used for the generation of electricity spread over an area of 1,400 square metres (15,000 sq ft). Another Romanian city, Alba Iulia, installed a total of 1,700 PV cells on several public buildings that have a rated power of 257 kW. Other cities include Giurgiu with 174 solar panels and 391.5 kW installed capacity and Saturn, Romania with 50 panels and 112 kW installed capacity.
Many photovoltaic projects are planned for Romania, totaling over 200 MW, and of these, about 61 MW were expected to be completed within 2012.
The first two industrial scale solar power plants in the country are the Singureni Solar Park completed in December 2010, and the Scornicesti Photovoltaic Park, completed 27 December 2011. Each is 1 MW.
A 32 MW project in four sections of 8 MW each is planned for Gătaia, and a 48 MW solar park is planned for Segarcea.
The Romanian State supports the production of solar / PV energy by offering six (6) green certificates for each MWh produced and injected into the grid. One green certificate will be traded on a regulated market (i.e. OPCOM) with a price that varies between EUR 27 to EUR 55 per green certificate, subject to indexation with the Euro zone inflation rate. However, due to the reduction of the cost of technology, the Romanian Energy Regulatory Body (i.e. ANRE) considers reducing the number of green certificate in the first half of 2012. In order to protect the interest of the solar / PV producers and for an appropriate guidance through the Romanian RES-E issues, the Romanian Photovoltaic Industry Association was created. Solar / PV energy is expected to be the second most active developed source of energy, after wind.
