A research on design and evaluation of BIPV

Building Integrated Photovoltaic (BIPV) systems are expected to increase significantly in the forthcoming years because of its friendliness with natural environment. This paper discusses design and evaluation of BIPV. A novel way to calculate tilt angle is presented to reduce the impacts of shading and maximize power output, followed by a design example to show its effectiveness. In system evaluation, levelized cost of energy (LCOE) method is used to evaluate the economy of designed system and output optimized tilt angle and LCOE optimized tilt angle are obtained. Government's incentives are more crucial for the improvement of BIPV's LCOE. Life-cycle emission analysis is used to quantify environmental benefits of BIPV systems.
