Basic Difference Between Net Metering vs Gross Metering – Visol India – Solar Panel Installation Company
Major Priyanka Gupta Over the past year’s pandemic time, people are adopting solar more & more in India. The government has also taken a great initiative & set up many large utility-scale power plants in India. India has set a target of 175 GW solar energy by 2022, which includes 40 GW rooftop solar. So rooftop solar is a very important segment to reach the target.
What is Rooftop Solar?
In a rooftop solar system, solar panels are placed on top of roofs of the building like commercial, institutional or residential buildings. They capture the light energy emitted by the sun and convert it into electrical energy. This setup is completely independent & owned by a single or more person.
In this system, there are two types of policy for the consumer who generate electricity from the rooftop solar PV system:
1. Net Metering
2. Gross Metering
Net Metering
The net-metering system helps solar consumers reduce their electricity bills. In net metering, when the solar system produces electricity, electricity first goes to the consumer’s home load, only then does the excess power go to the local power grid.
When the load of the consumer’s house increases and more power is required, electricity is imported from the local power grid. In this process, the consumer uses a bi-directional meter for measuring the exported electricity to the local grid and the imported electricity from the local grid. At the end, when the power consumption bill is generated, if the exported electricity is more, then the consumer gets credits for the excess energy injected into the grid. This can be carried forward to the next month or reimbursed at a rate provided by the state authority. & if the imported electricity is more, then the consumer will pay the bill for the excess amount of consumed electricity at the same rate provided by the state authority.
In net metering, the consumer uses the local grid as battery storage. which can be used to stabilize the solar energy demand and provide energy independence and sustainability.
As we know, tariffs & policies are different in every state, it makes solar a workable option at one place and a non-workable option at another. For applying net-metering policies successfully, the tariffs and policies must be market-driven rather than regulated.
One more issue in net metering policy, the solar system is connected to the grid, if the grid turns-off, the consumer cannot use the electricity generated by the solar system as the grid-tied inverter turns off the supply of power from the PV system.
Gross Metering
Gross metering technology is completely different from net metering. In gross metering, all the electricity generated by the consumer’s rooftop system is exported to the local grid. After that, the required energy for home consumption is imported from the grid. In this policy, consumers’ bill-paying process will be the same as per the tariff decided by the concerned state authority for the consumed units. Those electricity units which is supplied to the grid by the consumer will be determined by the state and will be regulated from time to time. The consumers are paid a feed-in-tariff decided by the respective state nodal agencies for the electricity injected into the grid.
So, this is the basic difference between gross metering and net metering policies. If you liked this information or you want to give any kind of suggestion, then you can comment below in the comment box. Stay connected for important information with Visol India.
