Investigation on Viability of Solar Panel Covered Carpark Project for Inti International University

Abstract

This project aimed to study feasibility of implementing solar panels into Inti International
University, Nilai academic block carpark area, forming solar carports. Capital calculation as well
as breakeven calculation for the whole project are predicted in order to examine viability of project
in long run. First of all, measurement of planned covered parking area was carried out and
estimated total covered area is about 8520????2
to cover 822 parking slots. A shading analysis has
been carried out on planned covered area as shading impact may affect performance of panels and
creating hotspot on shaded cells and eventually damage solar cells. Based on above, parking area
located near sport facilities of Inti Academic Block were considered. Carports structure to cover
such area has been designed and cost of carports structure is about RM190k. For solar system, a
real quotation has been requested from Solar Company named Plus Solar in order to obtain an
accurate calculation of capital where solar system consists of 72 pieces of JA Solar 375Wp
Monocrystalline panels, forming a 27kwp (kilowatt-peak) solar system that potentially saves an
average of RM 15k per year. As cost for solar system is RM 194,400, the total capital of this solar
carport project is approximately RM 465k. By considering tax incentives provided by government
including GITA & CA tax incentives, and in addition consideration of 0.65% for annual derating
of solar system and 3% of increment for OPEX annually, as well as RM 14,924.29 of average
annual electricity bills saving (for 30year), and this solar carport project requires 25 years and 2
months (25.17years) to reach its breakeven point.
