FLAT ROOF THIN-FILM PV COMPARED TO TILTED THIN FILM AND CRYSTALLINE PV

摘要

A 36 kW (DC-rated) building integrated photovoltaic system on a light industrial building has been installed with electric power meters and temperature probes to test and compare performance of three different types of solar panels. The first is a unique solar design which consists of two 2,560 watt arrays of unframed thin-film panels placed directly on a flat insulated spray-applied polyurethane foam ("SPF") roof- -ElectroRoof™. These two arrays will be subjected to different conditions and compared to a third 2,552 watt framed thin-film array mounted with an adjustable tilt angle, and a fourth 2,500 watt crystalline array also mounted with an adjustable tilt angle. These three types of PV technology have been compared in both tilted and horizontal positions under variable maintenance regimes.
