Increasing Energy Efficiency Using Photovoltaic Panels

Abstract The paper analyses the way of design of photovoltaic systems. The objective of this paper is to study the production capacity of electrical energy and the way it is influenced by real time conditions. In order to realize some energetic models that could be implemented on a large scale and used as a model of good practice we used photovoltaic systems of 3 dimensions: 60 PV panels, 100 PV panels and 160 PV panels respectively. The present study considered the climate conditions of the city of Cluj-Napoca for 12 months. It considered the consumption profile (hourly consumption) and the period of the year (summer, winter, etc.) for 3 typical buildings. We used Matlab/Simulink software for simulations. The result is an estimation of the production of electrical energy for renewable sources and the reduction of GreenHouse Gases (GHG). The aim is to reduce both GHG and the energy consumption from conventional sources.
