Abstract: | Building-integrated photovoltaics (BIPV) have various installation types, of which the photovoltaic (PV) shading-type module combines the effects of generating electricity and reducing heat gain of building envelope. The aim of this dissertation is to find out the optimal tilt angle of PV shading-type systems in Hong Kong, namely a tilt angle at which the PV module generates the maximum electricity by using the solar energy. The simulations were conducted based on the EnergyPlus which is a computer program for simulating the building energy consumption. The ten-story building model was designed in Open Studio with an area of 150 m2 per floor. Tilted angles of 15. to 30. were chosen with an interval of one degree and three different orientations of PV modules were simulated. The output results showed that the south-facing PV shading-type modules had more electricity production than the east-facing and west-facing ones. The power output of the PV shading-type modules was 175.5KWh, 234.0 KWh, and 197.6 KWh per unit area in the east, south, and west orientation respective with tilt angle 27.. In addition, the PV shading-type modules could reduce more heat gain through southern window than that of through eastern and western windows. According to the simulation result in this study, the optimal tilt angle of PV shading-type modules installed in Hong Kong was 27. facing south in considering both the power production and heat gain reduction by the PV shading-type module. |
