Abstract :
This paper has discussed designing and economic analysis of BIPV systems. For system designing, two major problems: shading and tilt angle calculation are analyzed. A new way to calculate tilt angle so as to reduce the impacts of shading and maximize power output is presented, followed by a designing example to show its effectiveness. In economic analysis, LCOE method is used to evaluate the designed system with a comprehensive way to find the LCOE optimized tilt angle. Comparisons between output optimized tilt angle and LCOE optimized tilt angle are made in this paper with the conclusion that the two angles are almost equal in BIPV systems and governments´ incentives are more crucial for improvement of BIPV´s LCOE.
