Case Study of the Day: Solar Rooftop Systems in Residential and Industrial Sectors in Tamil Nadu

Table of Contents

Introduction

Tamil Nadu is one of the leading states in India in terms of solar rooftop installations. The state has a strong solar policy in place, which provides financial incentives for both residential and industrial consumers to install solar rooftop systems.

Residential Sector

In the residential sector, the Tamil Nadu government offers a subsidy of up to Rs. 20,000 for the installation of solar rooftop systems. This subsidy has been a major driver of solar rooftop adoption in the state. In addition to the subsidy, the Tamil Nadu government also offers a net metering scheme, which allows consumers to export any excess solar power generated to the grid and get compensated for it.
As a result of these policies, the number of solar rooftop installations in the residential sector in Tamil Nadu has increased significantly in recent years. In 2022, the state had an installed solar rooftop capacity of 2,500 MW, of which 1,500 MW was in the residential sector.

Industrial Sector

The Tamil Nadu government also offers a subsidy of up to Rs. 50 lakhs for the installation of solar rooftop systems in the industrial sector. In addition to the subsidy, the Tamil Nadu government also offers a capital subsidy of up to 30% of the project cost for solar rooftop systems installed in industrial clusters.
As a result of these policies, the number of solar rooftop installations in the industrial sector in Tamil Nadu has also increased significantly in recent years. In 2022, the state had an installed solar rooftop capacity of 1,000 MW, of which 500 MW was in the industrial sector.

Benefits of Solar Rooftop Systems

Reduced electricity bills: Solar rooftop systems can significantly reduce electricity bills, especially for consumers who have high electricity consumption.
Increased self-reliance: Solar rooftop systems can help consumers become more self-reliant in terms of their electricity needs. This can be especially beneficial during power outages.
Environmental benefits: Solar rooftop systems generate clean and renewable energy, which helps to reduce greenhouse gas emissions and improve air quality.
Financial incentives: The Tamil Nadu government offers a number of financial incentives for the installation of solar rooftop systems, which can help to make them more affordable.

Conclusion

Solar rooftop systems are a viable and affordable option for both residential and industrial consumers in Tamil Nadu. The state government’s strong solar policy has helped to drive solar rooftop adoption in the state, and the number of installations is expected to continue to grow in the coming years.
