Performance analysis of roof-mounted photovoltaic systems The case of a Norwegian residential building

摘要

Currently, the application of solar Photovoltaic (PV) systems on energy efficient buildings such as passive house, zeroenergy building (ZEB) and net-positive energy building (NPEB) is becoming increasingly attractive, particularly in Europe andNorth America. The rooftops of residential and commercial buildings are ideal places for the installation of PV systems. Thework presented in this article aims at parametric analysis of PV systems applied to a 100 m2 flat rooftop of a Norwegianresidential building in Oslo. The study shows the effect of PV module types, the modules’ row spacing, and installation tilt angleon the electrical energy yield. The study also includes the economic and environmental aspects of a selected PV system
