Abstract
Abstract Presently, a green building concept is the design trend for new building. The Shading Device Integrated Photovoltaic system (SIPV) is one option can be applied for building energy conservation. Although, SIPV has some weakness when a building creates the shadow on SIPV by the sun ray projection. Nevertheless, SIPV operation has many benefits that are reduction and compensation the cooling load of air condition system that it follow from building code as OTTV indicator. Furthermore, Design can avoid a high performance glass window that is an expensive material. Therefore, the aim of this paper is to evaluate the annual energy yield per square meter of SIPV of the different slopes and directions of SIPV installation and different types of PV module as used for SIPV was compared. The evaluated location refers to building in Bangkok as 14o North latitude. The results shown that SIPV produces maximum energy yield when the slope nearly 120o on South, Southeast or Southwest direction, which is installed on the exterior wall that has the diffuse reflectance value approximately 30% like a rough semi-glossy surface. Amorphus Silicon and Polycrystalline Silicon technology produces the annual energy yield is 84 and 149 kWh/m2-Year respectively. Which replaces absolutely the cooling load from the glass area is 0.85 and 1.51 m2 respectively.
