Methodology to Calculate the Energy Consumption and Supply for One Family House in Buildings

A case study of one house has taken for taking care energy demand, crisis and energy supply for one family or one house. It is one step to save environment climate in world, It is necessary for large population of world (especially India and China) is increasing with an alarming rate, there is an increase in the demand of conventional energy resources leading to its depletion, therefore emphasis is now given on the resources which will not only fulfil the demand of energy requirement but also provide eco-friendly environment for its inhabitant. This paper deals with the overall setup of solar PV system (including capacity required and cost incurred for its component) in order to meet the need of electrical energy requirement for a family of four people with their basic need of energy to run their basic household appliance without taking any energy from grid. As one family buildings become more energy efficient, small power equipment with all appliance are an increasingly significant source of energy end-use and consumption for one family and one apartment.
