ON-GRID SOLAR SOLUTION
An on-grid solar system, also known as a grid-tied solar system, is the most widely deployed form of rooftop solar across the world. These systems do not need any batteries and are connected to the utility grid power. It is best suited for customers with stable grid power and minimal power cuts. Other than homes, even educational institutions, industrial units, commercial establishments use these systems as their primary source of power. An on-grid system is designed to first allow solar energy to be consumed by the customer. Beyond this, if the customer needs any excess power, it is drawn from the grid. If the customer’s energy requirement is lower than power generated from the solar system, excess solar units are exported to the grid. This is possible through a “Net-meter”. The Net meter is provided by the electricity board, Net meter calculates how many units has your solar system generated and transmitted to the electricity board and also how many units have been consumed from the electricity board. Mandatory requirements are the need to check the sanction load mentioned on the electricity bill , get feasibility certificate & net Metering permission from the electricity board.
