You have opted for on-grid solar PV panels because you want to get the benefits of solar energy with a reliable power supply. In this kind of solar power system, there is an element called net metering that helps you, and the DISCOM (Distribution Company), with how much power you have generated with solar panels and how much you have drawn from the grid.
How does solar net metering work? In this blog, we will demystify this amazing piece of equipment in your sophisticated rooftop solar system. We will also delve into the remarkable benefits that net metering offers, including its role in optimizing the sustainable future that solar energy is building.
How Does Solar Net Metering Work?
Net metering is a billing mechanism that allows solar system owners to feed excess electricity they generate back into the grid.
In a net metering system, a special meter tracks the electricity flowing in both directions—into your home or business and back into the grid.
Imagine it’s a bright sunny day. Your solar panels may generate more energy than your consumption needs. In such instances, the system seamlessly sends the surplus electricity to the power grid using net metering. This mechanism ensures that you receive credits for the excess electricity you contribute. These credits come in handy when your energy usage surpasses your solar generation, such as during nighttime or cloudy days.
Here’s a step-by-step breakdown of how net metering works:
- Energy Generation: When your solar panels generate more electricity than your premises consume, the excess energy is sent back to the grid.
2. Grid Interaction: During times when your solar system doesn’t produce enough electricity (e.g., nighttime), you draw power from the grid to meet your energy needs.
3. Metering and Billing: The net meter measures the net difference between the electricity you consume from the grid and the excess electricity you contribute. This net difference is what you’re billed or credited for, depending on the energy flow.
Benefits of Net Metering
1. Reduced Electricity Bills: With net metering, you can significantly reduce your electricity bills. By generating surplus energy during the day, you offset the energy you consume from the grid, leading to substantial savings.
2. Increased Return on Investment: Net metering allows you to make the most of your solar investment. By feeding excess electricity back into the grid, you earn credits that can be utilized when your solar system produces less energy, such as during nighttime or cloudy days.
3. Environmental Impact: Embracing net metering contributes to a greener and more sustainable future. By generating clean energy and reducing your reliance on fossil fuels, you actively reduce your carbon footprint and combat climate change.
4. Grid Support: Net metering aids in maintaining a balanced grid. The surplus energy you contribute during peak solar production hours can be utilized by other consumers, reducing strain on the grid and promoting energy stability.
Net Metering Regulations and Policies
India has several policies and regulations related to net metering for rooftop solar systems. Here are some of the significant ones to know.
1. System Size Limit: Net metering is allowed for systems ranging from 1 kW to 1 MW, with a 50% cap of the sanctioned load (residential and MSMEs enjoy 100%).
2. Load Limit: Net metering is applicable for loads up to 500 kW or the sanctioned load, whichever is lower.
3 Metering Arrangements: Depending on State Commission regulations, net metering can be implemented through net metering, gross metering, net billing, or net feed-in arrangements.
4. Solar Energy Meter: DISCOMs may install a solar energy meter to measure the total solar energy generated by a prosumer’s grid-interactive rooftop solar system.
5. State Policies: Different states in India have implemented net metering policies, including provisions for the buyback of excess electricity generated through solar panels.
It is worth noting that net metering regulations are subject to periodic updates and amendments. We advise consumers to stay informed about the latest developments in net metering policies and consult local authorities or solar energy experts for guidance on installation, compliance, and financial implications.
Is the Net Metering Right for You?
Net metering is an attractive option for homeowners, businesses, and institutions looking to harness the benefits of solar energy. If you have a solar system installed or are considering investing in one, net metering can amplify your savings and contribute to a sustainable energy transition. However, it’s essential to assess your energy consumption patterns, local net metering policies, and potential system size to determine if net metering aligns with your specific needs.
