Photovoltaic module solar energy is a renewable source of energy that uses solar radiation to produce electricity. It is worked on the so-called photoelectric effect, by which semiconductor materials are able to absorb photons (light particles) and release electrons, generating an electric current in form of Direct Current. Which then converted into Alternative current with the help of alternator. There is notable research is going on to use various Straight PV Modules and their types of System on the basis of their operation as alternative of electricity. Solar power systems derive clean, pure energy from the sun. Traditional electricity is sourced from fossil fuels such as coal and natural gas. Installing solar panels on home, Educational Institute and open spaces helps combat greenhouse gas emissions and reduces our collective dependence on fossil fuel. In present assessment Installation of roof top solar PV modules for reducing Electricity bill by using On-grid power system by net metering. Here energy generated by this solar pv module solar plant is transmitted to the electricity power grid and on compensation from electricity board Electricity bill reduces to minimum or extra arears provided to consumer. In traditional way to production of electricity fossil fuels is used which continues to rise producing high levels of carbon dioxide (CO2) which climatologists believe is a major cause of global warming. Similarly, electricity from various Electricity Boards and manufactures hikes their prices by day by day which is affect the unbalanced in the cost and profits of the individuals and its show the impact on social economic life of the persons. Whereas solar energy which is get from Sun is in bulk and its cost nothing. Initial Cost and maintenance cost is low as compare to other source energy.
