“Interservice Uzunovi“ PLC solar division was established at the beginning of year 2009 by the experienced entrepreneur Krasimir Uzunov, in accordance with the commitment of Bulgaria about fulfillment of Directive 2001/77/EU on the promotion of electricity produced from renewable energy sources in the internal energy market
Key company advantages are:
• Long term relationship with SHARP (leading producer of photovoltaic modules)
• Partnership with SMA (inverter producer)
• Good relations with governmental and administrative bodies
• Partnership with well-known European consultants and specialists in renewable field
• Land acquisition at very competitive prices
SOLAR PARK RAVNA GORA
The company’s first built photovoltaic project is situated in the land of Ravna Gora village, municipality Avren with installed capacity of 5MWp. In accordance with the Bulgarian solar map it is situated in zone with sun radiation of 4,25kWh/m2/day or 1450-1500 kWh/m2/year. Total land area is 309 dka, as the photovoltaic modules are placed on 200 dka.
Legislation
The solar project have obtained all necessary documents in accordance with the Bulgarian legislation law, including Building Permission, Preliminary and Final Contracts with EON, Contract for purchase of electricity, Permission for commissioning and positive statement from Electricity System Operator about the possibility for connection to Electric Line Entry 20kV “Bolyiartsi” from „Staro Oryahovo” substation .
Technology
For the implementation of Solar Park Ravna Gora “Interservice Uzunovi“ PLC used the best components suppliers and the most up to date technologies on the market, as follows:
Photovoltaic panels SHARP NA121GJ – the thin-film modules are the last development of the biggest producers and their main advantage is their possibility to collect the sun rays in bad weather conditions as well. This allows a greater length of the proceedings during the daylight.
Inverters SMA – SMA transformerless inverters allow higher system efficiency due to direct connection to the medium-voltage grid. These are the first central inverters that fulfill the requirements of the European medium-voltage directive.
Mounting structure TATA Steel – choosen mounting construction is designed and produces by TATA Steel, Great Britain, one of the biggest world producers and has 25 years full guarantee. The fixing of modules is by sliding in, which allows tide connection on long side of the modules.
Solar cables HIS Solar – this company is well-known in this sector and one of the leaders of solar cables and components production.
Quality
In order to maintain high quality during the design, implementation and exploitation „Interservice Uzunovi” PLC collaborates with consultants and world-known organizations in the renewable energy field, as follows:
TUV Rhainland – world-known organization, looking after the products and services quality, who participate in every stage of the solar park implementation.
SGS Bulgaria – international recognized company. By its Bulgarian licensed office, SGS is responsible for the independent supervising of the project.
Central Laboratory of Solar Energy and New Energy Sorces - Bulgarian Academy of Sciences – in collaboration of science and business, „Interservice Uzunovi” PLC works together with representatives of Bulgarian Academy of Sciences, who develop science experimentations in the renewable sector.
