Session

Energy Efficiency Engineering

Description

This paper presents the results obtained from monitoring a 3.9 kWp grid connected photovoltaic system, influenced by the climatic characteristics of a given geographic area in which the PV system is installed, as well as the orientations and types of system modules. The 3.9 kWp system consists of two types of photovoltaic modules, monocrystalline silicon and polycrystalline silicon, inverters and other measuring and monitoring equipment. The methodology consisted of market research of these systems and component selection, site analysis, and designation of the appropriate area for their installation. All the tests were performed in PVSyst software. The photovoltaic system connected to the grid is installed in order to supply with electrical power the laboratory and the network respectively. This photovoltaic system also contains accumulator batteries that enable the supply of electricity to the building even in the case of lack of electricity from the electricity network as well as during the time when there is no sun and there is no possibility of generating electricity from photovoltaic systems. In this paper, the 3.9 kWp system is simulated in three different directions in the south, east and west, as well as in the two slope angles of the modules, the angle 45˚ and 32˚, in order to find the optimum orientation and the slope angle which enables the highest output of energy. During the analysis, the following system parameters were calculated and evaluated: average generation per kWh per day, solar radiation, daily temperature, monthly average system parameters, module output energy, network injected energy and performance ratio, losses due to modification of the modules, system losses, inverter losses and cell temperature losses. The results obtained will enable the evaluation of the work and use of photovoltaic systems in the conditions of Kosovo.
