Economic Sizing of Solar Array for a Photovoltaic Building in Malaysia with Matlab

This article illustrates a simulation method to find a sizing and economic of a required photovoltaic array for a photovoltaic building in Malaysia. This paper represents the result using by Matlab software and also mathematic equation. It is known that the important factor for photovoltaic system is cost of a system, and because of several kinds of the photovoltaic array we have the right to select the best array with the best efficiency and best price. The popular types of materials are crystalline and thin films, which have differences in terms of light absorption efficiency, energy conversion efficiency, manufacturing technology and cost of production. Different kinds of crystalline materials like a mono-crystalline, polycrystalline are available. In this paper, the generated current and generated power by the photovoltaic array is calculated according to daily solar irradiation when the case study is Malaysia. Think over generated power of each array´s and also according to required energy for a typically building, the number of photovoltaic array is estimated then the cost of the solar array is calculated. System is simulated by Matlab software, and the results are discussed. The simulation is about sizing and economic in order to select the best array for photovoltaic system to have a optimize system according to size and price of the system.
