An on-grid solar system or a grid-tied solar system, is a setup of solar power which is installed to leverage the solar energy at homes, educational institutions, commercial establishments, industrial units, etc. It is one of the most widely used solar systems across the world. Such systems are not reliant on batteries and are well-connected with the utility grid. Furthermore, there are two requirements for this system to run seamlessly:
In an On Grid Solar Rooftop System, the solar panels absorb solar energy from the Sun and transform this energy into electrical energy i.e. Direct Current (DC). This Direct Current is converted into Alternating Current (AC) through Solar Inverters.
The consumer will never lack access to power and there will never be a power outage as electricity will be available all the time either from the solar panel or from the main grid.
As there are no batteries involved, the cost of On-Grid Solar System is comparatively lower than the other kinds of solar systems. Its power production is also higher than the other kinds of solar systems. Due to considerable reduction in monthly electricity bills and minimal maintenance, the customer can expect a gain of 25-30% in ROI.
Many initiatives by the current Government offer 30-55% solar subsidies covered under the Jawaharlal Nehru National Solar Mission (JNNSM).
Due to Energy Independence or lower reliance on the power grid, there is a drastic reduction in the electricity bill. You gain from net metering as the excess power is sent back to the main grid, providing you with further reduction in electricity bill or earning you credits.
An On-Grid Solar System is less expensive and more affordable than an Off-Grid Solar System as it does not need batteries. It can be installed on the rooftops of various establishments including homes, housing societies,commercial buildings,governmental agencies, community centres, for-profit businesses, etc.
The solar panels of an On-Grid Solar System last long for 25+ years. The equipments that come with an On-Grid system are durable and requires minimal maintenance.
