Design and development of mini hydropower system integrated for commercial building

In this power generation system, the abundant rainfall in Malaysia will be fully utilized through a gutter roof system, down into a series of pipelines which leads to a power generation system through turning of the mini hydro turbine. The particular system consists of several subsystems which make up the entire system, which shows the rainwater flow and usage from the beginning to disposal. 3D designs of the system was done utilizing the Solid Works 2015 software, and its site of interest is located at the College of Engineering(COE) BN-Building of Universiti Tenaga Nasional (UNITEN). Through usage of Solid Works 2015 and ANSYS FLUENT 16.0, the project has been able to simulate rainwater flow in the system which leads to the study of the rainwater characteristics alongside stress-strain analysis on the entire structure of the system. Finally, cost analysis was performed which sums up to an initial investment of RM 250k. The project will break-even at the 19^th year, and is expected to yield a net profit of RM 145k at the end of its peak performance life.
