Solar net metering has revolutionized the way we harness solar energy and contribute to a sustainable future. This billing arrangement allows solar energy system owners to not only generate clean electricity but also receive credits for the excess power they feed back into the grid. In this blog, we will explore the benefits of solar net metering and provide a guide on how to install a solar meter for those considering this renewable energy option.

Benefits of Solar Net Metering:

1. Cost Savings: One of the significant advantages of solar net metering is the potential for cost savings. By offsetting the electricity consumption from the grid with credits earned from excess solar generation, consumers can significantly reduce or even eliminate their electricity bills. This financial incentive makes solar energy more affordable and accelerates the return on investment for solar panel installations.
   
   

2. Energy Independence: Solar net metering empowers individuals and businesses to become more energy independent. By generating their own electricity, they rely less on the grid and are less vulnerable to rising electricity prices or power outages. It provides a sense of security and control over energy consumption.
   
   

3. Environmental Impact: Solar net metering promotes the adoption of renewable energy and contributes to a cleaner environment. By generating electricity from sunlight, we reduce reliance on fossil fuels and decrease greenhouse gas emissions. It is a step towards a greener and more sustainable energy future, combating climate change and air pollution.
   
   

4. Grid Support: Solar net metering has benefits for the grid as well. During times of peak demand, solar energy systems can help alleviate strain on the grid by injecting excess power. This can reduce the need for utilities to rely on expensive and polluting peak power plants. Solar net metering also encourages distributed generation, which enhances grid resilience and reduces transmission losses.

Installing Solar Meter

Installing a solar meter is a crucial step in implementing net metering. Here’s a general guide on how to install a solar meter:

1. Assess System Requirements: Determine the size and capacity of the solar energy system you plan to install. Consider factors such as your energy consumption, available roof space, and local regulations. Consult with a professional solar installer to evaluate your needs and design a suitable system.
   
   

2. Obtain Necessary Permits: Check with your local utility company and relevant authorities for any permits or approvals required for installing a solar energy system and net metering. Comply with the local regulations and ensure all necessary paperwork is completed.
   
   

3. Install Solar Panels: Engage a reputable solar installer to install the solar panels on your property. They will ensure the panels are correctly mounted, connected, and oriented for optimal solar energy generation.
   
   

4. Connect to the Grid: Coordinate with your utility company to establish the connection between your solar energy system and the electrical grid. They will install a bidirectional meter that can measure both the electricity you import from the grid and the excess electricity you export.
   
   

5. Finalize Net Metering Agreement: Sign a net metering agreement with your utility company, which outlines the terms and conditions of the arrangement. It typically includes details on the billing process, credit calculation, and any specific regulations or requirements.

Case study

In order to explain Net  metering, a 2 kW rooftop solar system (that generates 288 kWh per month on average) installed by a domestic consumer has been assumed. The applicable tariff slab is captured in Table 1 and average cost of supply (ACoS) at which the consumer is compensated for export of power has been assumed as INR 5.90/kWh.
