Technical and financial aspects of solar PV system for city dwellers of Bangladesh where green energy installation is mandatory to get utility power supply

Acute power crisis in Bangladesh stresses on the necessity of alternative sources of power generation in short, mid and long term basis. If solar panels be the alternative short term power source, then per unit production cost is a huge barrier in making this technology popular among the mass. But, urban house owners are under a mandatory condition of installing solar panels on their rooftop to get new electricity connection from power utilities. In such a situation, a solar energy rate has been proposed that will cover the solar electricity production cost, alternately called the cost recovery scheme. This rate is near about the maximum per unit rate of energy the government purchases from quick rental plants. Also, different types of solar modules have been compared. This can be a technical support for the city dwellers to who wants to buy solar panels. In this paper, a typical 6 storied building has been surveyed for the calculation of annual average electricity consumption and selected for solar PV design utilizing the unused rooftop of the building.
