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, zero energy building (ZEB) and net-positive energy building (NPEB) is becoming increasingly attractive, particularly in Europe and North America. The rooftops of residential and commercial buildings are ideal places for the installation of PV systems. The work presented in this article aims at parametric analysis of PV systems applied to a 100 m~2 flat rooftop of a Norwegian residential building in Oslo. The study shows the effect of PV module types, the modules' row spacing, and installation tilt angle on the electrical energy yield. The study also includes the economic and environmental aspects of a selected PV system.
