Use of Solar Energy for Green Building & Reduction in the Electricity Bill of Residential Consumer

This paper presents a case study of residential consumer from the urban area and suggests methods to make anenergy self-reliant house for the reduction in electricity bill. Unlike developed countries, India has to explore the use of renewable sources and other means to reduce the energy cost due to non-availability of real time pricing for LT consumers. Depending on the tariff offered by different utilities and the degree of necessity of various household appliances, a comparative study of energy cost is carried out. For the same sample residential flat, a solar PV plant is proposed and saving in energy cost with solar aid is discussed. Finally, a cost objective function is formulated and optimized using linear programming to justify the effectiveness of the proposed method.
