Abstract

One part of the building was deliberately made to face the sun was window. It is because windows function as a source of natural lighting for the house, so that the building becomes bright, not humid and healthy. Considering the position of the window that was deliberately made to face the sun, it is suspected that the window can also be integrated with solar panels to optimize the electricity that can be generated in buildings that use the Building Integrated Photovoltaic (BIPV) concept. The objectives of this study were explaining electrical power that produced by photovoltaic windows based on the direction of their placement position. This study uses an experimental method, the dependent variable was the power generated by the photovoltaic window and the independent variable was the position of the photovoltaic window (north, south, east and west). The study was conducted in July, when the sun^s position was north of the equator. The research data was collected every 20 minutes from 09.00 am to 03.00 pm. Data analysis using t-test. The discussion was carried out using the graph method. The result of this research show that there was a difference in the average electrical power produced by each window. The results show that the average electrical power generated by the north window was 1,64W- east 0,94W- south 1,07 W and west 1,57 W. Photovoltaic windows that have north, and west position were able to produce highest electrical power.
