Abstract

Due to rapid depletion of fossil fuels and environmental risk, several non-conventional sources of energy like water, wind, geo-thermal, nuclear and solar photovoltaic, have been taken into account for power generation. Solar energy is finite energy resources to meet up long term global energy crisis. In the last decade the demand of power in India has increased manifold, therefore government has announced the National Solar Mission of generating 100 GW of solar power up to 2022. Around 60% of the total National Solar Mission target is allotted to the national/international large-scale solar power developers/investors. Environmental friendly, reduced installation cost, improved power quality, abundant availability of source makes photovoltaic based distributed generation as one of the most popular alternative source of energy production. Many industries operate 24 hours in a day, practically every day of the year. They expect full reliability and availability from their power systems, with very low tolerance for outages or shortfalls. Such industries operate at a 70% to 90% annual load factor relative to their peak load, but peak loads can occur at any time of day in any season. Due to their inherent variability, most renewable technologies, like photovoltaic panels (PV) and wind, can only address a small fraction of the energy needs, and are not reliable enough for off-grid power so we propose a hybrid grid system for the same. This report analyzes the key barriers and bottlenecks faced by solar power and diesel power developers in achieving the target and their growth and propose an automated method to do the economic calculation of solar power plant at any location. We compare this with diesel plant economics to find the best possible power generation solution for situations. They could be singly used or in a hybrid system.
