India’s journey to adopting rooftop solar is closely tied to tax and policy decisions, and the latest Goods and Services Tax (GST) reform is a major milestone for the clean energy sector. By reducing GST on the renewable energy value chain from 12% to 5%, the government has lowered project costs and made rooftop solar systems more accessible for households, businesses, and institutions. When combined with schemes like the PM Surya Ghar: Muft Bijli Yojana, the impact on rooftop solar affordability is significant.
