Abstract
This paper presents the use of solar energy for generation of electrical energy through solar pho-tovoltaic (SPV) system to meet the load requirement of a domestic building. Complete design and economic analysis of SPV system for different costs of SPV module is done and compared with grid electricity for with and without storage conditions. The results of the study encourage the use of SPV system for a residential building and show that SPV system is an economically viable option to meet the exponentially growing electricity requirement for household applications in India.
Highlights
India faces a significant gap between electricity demand and supply
The cost of electricity generated from solar photovoltaic system with batteries is calculated to be Rs. 22/kWh, whereas the cost of utility electricity supplied to consumers is approximately Rs. 6.8/kWh for domestic purpose
This study presents the complete design and the life cycle cost analysis of the PV system for single household application
Summary
India faces a significant gap between electricity demand and supply. Demand is increasing at a very rapid rate compared to supply. According to the World Bank, roughly 40% of residences in India are without electricity. Blackouts are a common occurrence throughout the country. The World Bank reports that onethird of Indian businesses believe that unreliable electricity is one of their primary impediments of doing business. Coal shortages are further straining power generation capabilities. In order to meet the situation, a number of options are considered. Power generation from freely available solar energy is one such option. Most parts of India receive bright sunshine around 3000 hours in a year except Kerala, northeastern states and Jammu & Kashmir where sunshine hours are appreciable low
