This paper reviews the prospects of available renewable energy resources along with various private and government future project plans to incorporate renewable energy sources and their potentials as per context of Bangladesh. According to the approved renewable energy policy, the Government of Bangladesh (GOB) is devoted to facilitating investment in both public and private sectors in renewable energy projects to substitute contemporaneous non-renewable energy resources and to escalate the contributions of renewable energy based electricity generation. A plan has been initiated by the GOB to generate 5% of the total energy from renewable energy resources within 2015 and 20% by the year 2020. The aim of this paper is to provide an overview of the present condition of renewable energy resources in Bangladesh and hence, different types of renewable energies are discussed from global perspective to achieve a clear perception about solving the power crisis issues in Bangladesh with this sustainable approach.

This paper presents a circuit based simulation model for a solar photovoltaic (PV) module to examine the estimated electrical performance parameters with the changes of environmental parameter such as solar irradiation and temperature. Modeling and simulation of a solar PV module is presented based on Shockley diode equations. The Solarex MSX 120, a typical 120W PV module is chosen for model performance evaluation. The mathematical model for the chosen module is implemented on matlab with respect to various temperatures, solar irradiations, diode quality factors and model series resistances and obtained I-V and P-V characteristics curves were compared with the manufacturer's published curves which show precise correspondence to the model.
