Introduction

India’s Government has introduced a significant GST reform impacting the solar renewable energy sector starting September 22, 2025. With the GST rate on solar and renewable devices set at 5%, this change aims to make clean energy installations more cost-effective and accelerate the country’s green energy goals. GreatSun Power Pvt Ltd explains the new GST structure, its benefits, and what it means for your solar investments.

What is the GST Change?

The Goods and Services Tax (GST) Council has reworked the GST slabs from multiple rates to mainly two slabs: 5% for essential goods and 18% for others. Solar panels, inverters, and related renewable energy equipment are now taxed at 5%, down from a higher combined tax rate, making solar solutions more affordable.

How the New GST Affects Solar Renewable Installations

• The GST on solar products and services, including EPC contracts, will now attract a uniform 5% tax rate.

• Previous effective tax burdens, which included components taxed both at 5% and 18%, are simplified to a lower single slab of 5%.

• This reduces the upfront cost of installing rooftop solar and other renewable systems for households and businesses.

Benefits of the GST Reduction

• Reduced Project Costs: Lower taxes directly reduce the cost of solar installation.

• Faster Payback: The return on investment for solar energy systems improves with reduced tax incidence.

• Encourages Adoption: More homeowners and businesses are expected to switch to solar due to affordability.

• Supports Government Sustainability Goals: Boosts India’s push for renewable energy and carbon reduction.

Effective Date and Compliance

• The new GST rate of 5% for solar products and installations is effective from September 22, 2025.

• All solar vendors and consumers should update billing and accounting practices accordingly.

• Official government notifications and GST Council meeting reports provide the legal basis for this change.
