Optimal PV system dimensioning with obstructed solar radiationOptimal PV system dimensioning with obstructed solar radiation Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-09-281996enThis paper describes an analytical methodology for the optimised design of stand-alone photovoltaic (PV) systems installed at locations where the solar radiation is considerably shortened by obstacles, i.e. at the bottom of a gorge. A method for the computation of the real available solar energy incident on the PV panel is proposed, based on easily conducted measurements. The optimum tilt of the PV array, under such conditions, is obtained and a dimensioning procedure provides the optimal size of the PV-array/storage. The resulting system is tested by a verification routine. A case study, employing the complete algorithm proposed, is illustrated.Δημοσίευση σε επιστημονικό περιοδικό http://creativecommons.org/licenses/by/4.0/Renewable Energy1751-56 Kalaitzakis Kostas Καλαϊτζακης Κωστας Elsevier Photovoltaic energy systems Photovoltaic facilities Photovoltaic power plants Photovoltaic solar generating plants Power plants, Photovoltaic Power systems, Photovoltaic photovoltaic power systems photovoltaic energy systems photovoltaic facilities photovoltaic power plants photovoltaic solar generating plants power plants photovoltaic power systems photovoltaic Absorption, Atmospheric Atmospheric absorption of solar radiation Insolation Radiation, Solar Sun--Radiation solar radiation absorption atmospheric atmospheric absorption of solar radiation insolation radiation solar sun radiation
