The Conceptual Design of the Solar Photovoltaic Plant in Kopilica

The paper gives the conceptual design of the solar photovoltaic plant placed on the roof of newly reconstructed building of the University Department of Professional Studies of the University of Split. Solar photovoltaic plant is designed as a network-type, where all electricity produced by the plant is supplied to the electricity network. PVGIS application has been used for the estimation of average yearly electricity production from the plant that reached some 77.300 kWh. The technical solution for placing the photovoltaic panels on the building's roof has been proposed, as well as functional scheme of the photovoltaic plant. The assessment of investment is given based on the simplified economic analysis. The estimated payback period of investments is based on the conditions defined in the Tariff System for Electricity Production from Renewable Energy Sources and Cogeneration. The total investment in the solar photovoltaic plant is estimated to some 890,000.00 kn, while the period of cost recovery, considering the given conditions, to some 7.5 years.
