Kerala, renowned for its progressive stance on renewable energy, has implemented a Net Metering Policy designed to encourage the adoption of solar power. This initiative enables residential, commercial, and industrial consumers to install solar rooftop systems, thereby cutting down on electricity expenses while promoting environmental sustainability. Through its distribution companies, the Kerala government has streamlined the process for users to produce their own electricity, with surplus energy being fed into the grid for credit.
In this article, we’ll delve into how net metering operates in Kerala, explore the advantages of this policy, and break down the costs associated with setting up a solar rooftop system in the region.

**What is Net Metering?**
Net metering is a billing arrangement that permits individuals with renewable energy systems, particularly solar panels, to export excess electricity generated by their systems back to the grid. The exported electricity is measured, and users receive credits that can be applied to future electricity usage. Essentially, consumers are charged only for the "net energy" they consume, which is the difference between what they take from the grid and what they supply back.
Kerala’s net metering scheme aims to make solar power more accessible and cost-effective for consumers, reducing electricity bills and fostering the state’s transition to cleaner energy sources.
**Key Features of Kerala’s Net Metering Policy**
One of the most significant aspects of Kerala’s policy is its inclusivity. Both residential and commercial entities can benefit from this initiative, provided they meet certain criteria. A bi-directional meter is installed to monitor both the energy consumed from the grid and the energy supplied back. Excess energy is credited monthly, with any surplus credits carried forward to the following billing cycle.
**Eligibility Criteria**
To qualify for net metering in Kerala, consumers must:
- Be connected to the Kerala State Electricity Board (KSEB) or a local distribution company.
- Have a sanctioned load or contract demand that matches the proposed solar system’s capacity.
- Use systems ranging from 1 kW to 1 MW, with residential and commercial consumers limited to 80% of their sanctioned load.
**Billing and Settlement**
Under net metering, a bi-directional meter records both energy imports and exports. Users are billed based on the net energy consumed, which ensures transparency and fairness in billing. The settlement period is monthly, and any leftover credits are carried forward to subsequent billing cycles.
**Installation and Maintenance**
While consumers are responsible for the initial investment in solar panel installation, ongoing maintenance, such as regular cleaning and system checks, remains their duty. It’s advisable to work with approved vendors and certified installers to guarantee compliance with KSEB standards.
**Government Incentives and Subsidies**
The Ministry of New and Renewable Energy (MNRE) provides subsidies of up to 40% for systems up to 3 kW and 20% for systems between 3 kW and 10 kW. Additionally, Kerala offers further incentives to encourage solar adoption.
**Benefits of Net Metering in Kerala**
1. **Reduction in Electricity Bills**: By producing their own electricity, users can significantly cut down on utility costs. Exporting surplus energy earns credits that lower future electricity bills.
2. **Environmental Benefits**: Promoting solar energy usage helps reduce the state’s carbon footprint, encouraging a shift away from non-renewable resources like coal and natural gas.
3. **Energy Independence**: Solar energy empowers consumers to become more self-sufficient, shielding them from potential grid shortages and rising electricity prices.
4. **Financial Returns**: The payback period for a solar system typically falls between 5 to 8 years, after which the system provides free electricity for its remaining lifespan, often up to 20-25 years.
