The GST cut, effective from September 22, 2025, is expected to lower the cost of renewable energy projects. For example, a typical 3 kW rooftop solar system may become ₹9,000–₹10,500 cheaper, making solar energy more accessible to consumers and farmers under schemes like PM Surya Ghar and PM-KUSUM.
Minister Joshi thanked Prime Minister Narendra Modi for implementing the tax reduction during the Navratri festival. He noted that the change would boost investor confidence and help India add around 248 GW of renewable energy capacity over the next five years.
The Ministry of New and Renewable Energy estimates that the GST reduction will save ₹1,750 crore on 10 lakh solar pumps under the PM-KUSUM scheme. The move is also expected to make large-scale solar projects more affordable, accelerating the country’s transition to clean energy.
This tax reform is considered a key step in supporting sustainable development and energy independence in India, while attracting investments and fostering growth in the renewable energy sector.
