What Is Gross Metering In Solar? How Will Solar Gross Metering Affect Return On Investment?


The electricity generated by the rooftop solar system is integrated into the grid and, under these conditions, the output of the system meets the requirements of the grid.    

Grid meters allow utility customers who generate their own solar power to feed energy they do not consume back into the grid. The net meters credit solar customers with their electricity consumption and thus reduce their monthly bill. Most states have passed net meter laws, but the differences in state legislation and implementation mean that net meters can vary across different parts of the country.    

Grid counting is a policy that determines what rooftop solar owners pay for the electricity they feed into the grid. The net metering policy requires utilities to pay the retail tariff for electricity produced by rooftop solar panels, which is generally lower than the tariff paid by utilities to other electricity producers. On the other hand, net meters export solar power, which adjusts electricity bills to energy consumption.    

Consumer behavior shows that a consumer with a rooftop solar system of 5 kW, which generates an average of 600 kWh per month, would incur the cost of Rs99.75 per quarter in case of a gross count. Gross consumption measurement is compensation for the consumer through lower retail tariffs when he or she buys electricity from the disco. Under the scheme, discos lose no income, unlike net meters where they do.    

The supplier pays you an energy credit on your electricity bill per kilowatt-hour (kWh) of solar power that you feed into the grid. The idea is that consumers’ electricity bills will be adjusted if they are able to produce, for example, rooftop solar panels as part of their electricity needs. When surplus electricity is fed back into the national grid, consumers are compensated by the discos on a fixed feed-in tariff.    

When consumers install solar panels on their property, there are two things they can do with the solar energy they generate: they use it on their property or sell it to an energy company.

Solar incentives allow consumers to send excess energy back to the grid for a credit on their monthly electricity bill. Every time the solar panels produce too little, you can use the credit to offset the cost of the energy consumed by the grid.   

Today, most solar customers produce more electricity than they consume. Net meters let them export some of it back to the grid to reduce their future electricity bills. On average, 20-40% of the output of a solar plant goes back into the grid, where it serves as a customer load. Since it is more expensive to store electricity than to connect the system to the grid, surpluses are exported to the system, and deficits are imported from the grid.    

If the consumption of a solar system (e.g. A solar system on the roof) does not consume electricity during the holidays, the surplus electricity is fed back into the grid via a meter connection, the so-called grid meter. The shutdown ensures that the surplus electricity is transferred back to the grid and adapted as a net billing unit to subsequent electricity bills. The use of Net Metering to save and go solar net metering is a good solar policy because it allows you to save the electricity each unit of the electricity you generate from solar energy in the grid for later use.    

Net energy meters, also known as net energy meters (NEM), are the basic solar policy incentives that underpin the entire private solar industry. Net meters are not the only way utilities compensate homeowners for switching to solar, but they are the most common and effective solar policy. In fact, you can save thousands of dollars by offsetting your power needs from the grid thanks to net measurement over the lifetime of your solar system.   


Using solar energy to power your home has many advantages, from cleanliness to independence from the grid:

  1. The net energy meter, also known as the net energy meter or NEM, is a supply structure that requires your utility to buy the excess solar energy produced by your solar panels at the full retail price. If you use more electricity than the panels produce at night or on a cloudy day, you will need to pull electricity from the grid to run to your electricity meter.   
  2. One of the most important measures of the Electricity Rights of the 2020 Consumer Rule is that consumers can install solar panels on their land or roofs and resell the electricity produced to the utility, the Power Distribution Operator (Discom). In light of the rooftop boom last month, it was announced that the new rules will recognize prosumers as a class of consumers who generate electricity and sell it to the grid. With this system, known as gross metering, prosumers buy from the grid and reconnect to the grid in two separate streams.       
  3. In the gross census, all electricity generated by rooftop photovoltaic systems must be measured, regardless of whether it is consumed on-site or outside. The Gross Measurement introduces a system of credits for this electricity at a discount based on the year of installation. A bizarre, punishing, and unsupported twist that seems to be fueled by LePage is the obsession to stop rooftop solar installations, as shown above.    
  4. In September 2020, the Ministry of Energy (MoP) published the draft Electricity Rules 2020, which will streamline electricity supply and distribution. One of the most critical points of the draft revolved around gross and net meters for rooftop solar panels. If the scheme is approved, all roofs with solar projects with an output of at least 5 kW will be covered by the “net meter scheme,” and all projects over 5 kW will be eligible for a gross meter calculation.
