ENVIRONMETAL IMPACT OF SOLAR SYSTEMS – CASE OF SERBIAN RESIDENTIAL BUILDING WITH SOLAR COLLECTORS AND PV PANELS

Abstract

In the recent years, solar energy became the most common renewable energy source, because of its abundance and small pollution of environmental. In this paper, it is analyzed the environmental impact of installed solar system at Serbian residential building. The building has gas space heating or electric space heating and PV panels and solar collectors installed on the roof. Installed solar systems emit a certain amount of carbon dioxide in the atmosphere when generating electricity and heat. The investigations in this paper were carried out with the aim of determining the optimal size of solar systems, in which the minimum consumption of primary energy is realized. The residential buildings with variable types of PV panels are investigated. For optimal size of solar systems, emissions of carbon dioxide and emission payback-time (EPBT) are calculated. The buildings are simulated in EnergyPlus environment. Open Studio plugin in Google SketchUp was used for buildings design, Hooke-Jeeves algorithm for optimization and GENOPT software for software execution control.
