Bangladesh is a progressing country with huge population. Almost 75 percentage of the population lives in rural areas and only about 30 percentage of the rural households have access to grid electricity and about 42 percentage of the population no access to the electricity. It is highly difficult to extend high tension transmission lines to these areas as some of the places are separated from the mainland and from each other by wide rivers, creeks and hills. Renewable energy is considered to be the right choice for providing clean energy to these remotesettlements. Off-Grid energy systems are growing in popularity as an independent source of energy to satisfy electricity needs of individual households, small communities and commercial applications. Mainly in Bangladesh where the main grid is either not developed or the grid is noncommercial to extend due to remoteness of the location. A successfully installed Off-Grid energy system for several years to provide a reliable 24-h electricity supply to the inhabitant of an island. The objective of this paper is to analyze and design an off-grid energy system for Bangladesh consisting of PV panels, charge controller, battery and inverter to serve a remote locality. A mini solar grid of 21KWh capacity has been designed.
