Economic Analysis of Bi-Directional Net-meters with Orientation and Positioning of Solar Module

Abstract

In this paper, the methodologies and worldwide impact of the net meter are discussed with the points to be considered in positioning the solar panel for maximizing the self-consumption. In addition, the net metering policies associated with its financial factors are discussed. The depletion of fossil fuels drags the world to the paramount use of available renewable energy sources for power production in small and medium scales. In this, the power production using solar energy is playing a vital role as it is safe and pollution free. The solar PV system has made a good impact in different countries and it's fast-paced in the last two decades because of the increase in demand for electric power. Apart from the utility service to generate power by Solar PV power plants in large scale, this idea has been an attraction to the peoples and results in implementing the Solar PV in their building roofs to generate their own power in small scale. The rooftop solar PV systems made the consumers to support their residential load during the power failure, consuming less power from the grid and in advance, it can feed the excess power to the grid. By delivering the power to the grid the consumer becomes prosumer and experience economic return equal to the power delivered to the grid. Bidirectional net energy meters are useful for the consumers to keep in track of the amount of power that is transmitted to the grid (Solar power generated in excess) and received by the consumer (power received from the utility center). The main outcome of this net metering from the consumer side is the reduced total tariff when they fed the excess power to the grid.-Researches are being developed in the area of minimizing the losses, and maximum consumption with low cost affordable to build Zero Energy Buildings. In some parts of the USA, the government has come forward for free installation of the rooftop solar PV system in their people's house as awareness and receiving their excess power at a considerable rate. Without this Net metering technology, the utility cannot consume power from the consumer.
