80kW photovoltaic power plant was installed to cover the enterprise’s own energy needs. It was constructed on the roof area of a building in Sofia. The documentation for ERM West and Sofia Municipality, as well as the project in all necessary parts, were managed and prepared by VVT Engineering. The structure was designed and built by VVT Engineering Ltd. It is made of high-quality Schletter aluminum profile for thermal panels and consists of aluminum profiles that provide sufficient airflow and cooling for the panels. The power plant consists of 148 Bauer Solar photovoltaic modules with a capacity of 550W, each with a 20-year product warranty, and two Kostal Piko Ci inverters with capacities of 30 kW and 50 kW, each with a 10-year warranty. The entire construction of the power plant took 10 working days. After the photovoltaic power plant was built, all necessary declarations and quality certificates were issued to enable its commissioning.
