Prospects of solar systems in production chain of sunflower oil using cold press method with concentrating energy and life cycle assessment

The aim of this study is determination exergoenvironmental efficiency for using solar technologies in sunflower oil production Iran. Accordingly, the applications photovoltaic and photovoltaic/thermal systems were evaluated both agricultural industrial phases production. Energy results reveal that 1 ton consumes produces about 180,354 39,400 MJ energy, respectively. About 86% total energy consumption belongs to phase electricity with 32%, has highest share consumption. IMPACT 2002+ method cumulative demand life cycle assessment are applied 3 defined scenarios including Present, photovoltaic/thermal. Results indicate amounts climate change Present 24537.53 kg CO2 eq. . human health (90%), ecosystem quality (90%) (50%) all direct emissions. also illustrates 177,538, 99,054 132,158 1TSO?1, Furthermore, most contribution non-renewable resources fossil fuels (37%), nitrogen (52%) panels (39%) scenarios, Finally scenario best environmental-friendly scenario.
