Energy balance analysis of a stand-alone photovoltaic system, including variable system reliability impact

摘要: Official statistics estimate that almost two billion people have no direct access to electrical networks, 500,000 of them living in European Union and more than one tenth Greece. An autonomous photovoltaic system is the most interesting environmental friendly technological solutions for electrification remote consumers or entire rural areas. The primary objective this current study determine optimum dimensions an appropriate stand-alone system, able guarantee coverage energy demand located typical Greek territories using long-term measurements, under restriction minimum initial cost. Accordingly, impact acceptable reliability level on behaviour cost also examined. Finally, special emphasis laid detailed balance analysis selected configurations, hourly basis at least. According results obtained, a properly sized motivating prospect problems numerous existing isolated all around
