IMPLEMENTATION OF SOLAR SYSTEMS IN FOOD INDUSTRIES – CASE STUDY KRAGUJEVAC

Abstract

Energy management in the food industry is a continuous process, which includes monitoring the energy performance of the company and continually finding ways to sustain and improve it. At a concrete company located in Kragujevac, the installation of flat plate solar collectors (FPSC) and photovoltaic panels (PVP) on flat roofs of the plant was discussed to increase the energy-eco efficiency (EEE). Complete research was conducted numerically, using the EnergyPlus software. The results show that PVP annually can meet 3.65% of the electricity needs of the company, with a payback period of 22.6 years, while using the FPSC consumption of natural gas annually reduces by 14.64%, with a much shorter return on investment (12.05 years).
