Academic internship of students of the National Advanced School of Engineering (ENSPY) at the CURES during the year 2017(1)

From February 13 to July 13, 2017, the student Yolande Ebude of the ENSP of Yaoundé did an academic internship at CURES for a period of five months. The theme of her work is: "Designing a Solar Power System for Backup and Surveillance in hospitals".

In her study, Yolande Ebude proposes an energy supply using solar energy which is abundant in the Sub Saharan and the equatorial zone. This energy has little or no pollution compared to Diesel Generator set.
 In her approach, Yolande has established 4 essential steps for hospitals to design the solar energy supply system. She proposed algorithm for design which can be modified according to the hospital’s characteristic. The methodology was validated with two Cameroonian hospitals.The study reveals that for the first hospital, there is a contrast between the existing standby system (which is a 5 KVA Generator set with an annual Operation and Maintenance cost of XAF 1,900,400) and the proposed SOLAR ENERGY SUPPLY SYSTEM which has an investment of XAF 14 Million. But in the long run, the solution proposed by Yolande becomes less expensive with an annual Operation and Maintenance cost of XAF 432,000 and a Return on Investment 7 years and 4 months. Similarly for the second hospital, the existing system (grid + Generator set) has an annual Operation and Maintenance cost of XAF 2,280,960 whereas the proposed SOLAR ENERGY SUPPLY SYSTEM has an initial cost of XAF 13.5 Million but becomes less expensive on a long run with an annual Operation and Maintenance cost of XAF 432,000 and a Return on Investment of 6 years.
