Prototype of household inverter using dual-axis solar tracker to overcome shortage of energy

Abstract

Energy crisis is one of the biggest problems in developing countries. There is a big gap between generation and demand of Electric energy. Since the deposits of Non-renewable energy are limited, the only solution is to use Renewable energy. Solar energy which is present in abundance can play a vital role to overcome the energy deficiency. The potential of solar voltaic energy can also be exploited for averting environmental pollution and managing atmospheric emission. This research paper provides a proposal for design of an inverter using dual axis solar tracker installed on rooftop. The paper focuses on presenting the structure and application of a microcontroller based dual axis solar tracker which tracks the direction of the solar radiation thereby adjusting the movement of solar panel accordingly. This facilitates the sun to remain perpendicular to the PV panel throughout the day which makes the total energy received to be increased by 50–60%. The energy hence received gets stored in a chargeable battery. This battery has an inverter attached to it so that whenever there is a power-cut, the stored energy may be used to light up the appliances. The stated research aims at minimizing the dependence on power from national grid station to meet the daily energy requirements in both urban and rural areas of the country.
