Abstract

Cilj ovog diplomskog rada je procjena životnog vijeka fotonaponskog sustava. U teorijskom dijelu rada proučeni su planovi i strategije Europske unije kojima je cilj postizanje ugljične neutralnosti, tranzicije energetskog sektora na obnovljive izvore energije i energetske neovisnosti. U svrhu procjene utjecaja fotonaponskog sustava na okoliš proučena je metodologija životnog ciklusa proizvoda (engl. Life Cycle Assessment, LCA), standardizirana serijom normi ISO 14040. U radu je opisana konstrukcija i tehnologija izrade sastavnih dijelova fotonaponskog sustava instaliranog na površinu od 50 m2 krovišta stambenog objekta u Zagrebu predviđene vršne snage sustava od 9,72 kWp. Za taj sustav izrađen je model životnog vijeka u edukacijskoj verziji softvera GaBi. Metodom procjene životnog ciklusa izračunat je utjecaj svake životne faze fotonaponskog sustava na okoliš. Za fotonaponski sustav izrađen je i certifikat Izjava o utjecaju na okoliš (engl. Environmental Product Declaration, EPD). Cjelokupna provedena analiza u radu pokazala je kako fotonaponski sustav u manjoj mjeri utječe na okoliš od tradicionalnih izvora energije te da ima značajne prednosti u pogledu smanjenja emisija stakleničkih plinova.

Abstract (english)

The aim of this master’s thesis is to assess the life cycle of a photovoltaic system. The theoretical part of the thesis examines the plans and strategies of the European Union aimed at achieving carbon neutrality, transitioning to renewable energy sources in the energy sector, and achieving energy independence. To assess the environmental impact of the photovoltaic system, the methodology of life cycle assessment (LCA) standardized by the ISO 14040 series of norms, was studied. The thesis describes the construction and manufacturing technologies of the components of a photovoltaic system installed on a 50 m2 roof surface of a residential building in Zagreb. A life cycle model for this system was developed using the educational version of the GaBi software. The impact of each life cycle phase of the photovoltaic system on the environment was calculated by applying the life cycle assessment method. An Environmental Product Declaration (EPD) was also created for this photovoltaic system. The comprehensive analysis conducted in the thesis showed that the photovoltaic system has lesser environmental impact than traditional energy sources and offers significant advantages in reducing greenhouse gas emissions.
