Size optimization of a PV system installed close to sun obstacles.Size optimization of a PV system installed close to sun obstacles. Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-09-291996enThe assessment of the optimal size of a PV-array/battery-storage system, when the incident solar radiation is considerably obstructed, is presented in this article. An optimal dimensioning method is proposed based on a new procedure for the calculation of the actual solar radiation on the array surface, for installations located near obstacles. The optimum tilt of the PV array is also computed and the resulting optimal PV-array/battery-storage system is evaluated by an appropriate routine. The results of the application of the complete algorithm for a real case study inside a gorge are illustrated.Δημοσίευση σε επιστημονικό περιοδικό http://creativecommons.org/licenses/by/4.0/Solar Energy457291-299 Kalaitzakis Kostas Καλαϊτζακης Κωστας Stavrakakis Georgios Σταυρακακης Γεωργιος Elsevier solar radiation PV array case study
