Photovoltaic Power Plant Karlovo
Project Description
Photovoltaic power plant with a capacity of 80 kWp, connected to the distribution network of EVN ELECTRIC POWER DISTRIBUTION LTD, on LOW VOLTAGE level to existing concrete complete transformer stations (CCTS) 0,4 / 20kV, via 300 meters cable route length. The plant is mounted on flat terrain, the panels are fixed on steel construction. The construction is divided into 8 pieces, called “bedding”, each of which carries 40 solar panels with a total output of 10 kWp.
Solar panels:
The installed 320 pcs. photovoltaic panels are CN SOLAR Technology, delivered by TAO Engineering on behalf of the investor.
PV inverters:
For converting electricity from the photovoltaic generator from constant to variable as a request of the investor are used 8 photovoltaic inverters of the German company SMA - a particular model Sunny Tripower 10000 TL. This transformerless inverter with a power output 10 kW, suitable for both indoor and outdoor installation.
Constructive solution:
The panels are designed to be fixed on steel “bedding” made of cold rolled profile sheets stainless steel of Voestalpine. Finishing layer is Zn600. The structure is only with bolted connections without welding because of preventing dammages on the anti-corrosion coating. The foundation is piloted using steel poles with a length of 2.6 meters, reaching the design depth of 2.1 meters.
