India’s renewable energy sector received a major boost in the Union Budget 2026–27, with targeted duty reductions aimed at lowering costs and strengthening domestic manufacturing. The government has reduced effective duties on solar modules to 20% and rebalanced Basic Customs Duty (BCD) and cess on solar cells to improve overall project viability.
These changes come at a critical time as India accelerates toward its ambitious clean energy targets and the Net Zero 2070 vision.
Lower Costs, Better Project Economics
One of the biggest impacts of the budget will be improved financial viability for solar projects. Lower duties on modules and cells directly reduce capital costs for utility-scale plants, commercial rooftop systems, and industrial installations. For businesses evaluating solar, even a small percentage reduction can significantly shorten payback periods and improve long-term returns.
Additionally, the removal of the 7.5% BCD on sodium antimonate—a key raw material used in solar glass—will help domestic manufacturers lower production costs. This move strengthens India’s solar supply chain and supports the growth of local players competing with global manufacturers.
Strengthening Domestic Manufacturing and Storage
The budget also extends duty exemptions on capital goods used in lithium-ion battery cell manufacturing. This is a strategic step toward integrating energy storage with solar projects, especially for industries, data centres, and large commercial consumers that require reliable round-the-clock power.
With states like Gujarat, Rajasthan, and Tamil Nadu expanding solar capacity and companies such as Tata Power and Adani Green investing heavily, policy support for manufacturing and storage will help India build a more resilient renewable ecosystem.
What This Means for Businesses
For commercial and industrial consumers, the timing is significant. Lower equipment costs, improving storage economics, and supportive policies mean rooftop solar and hybrid solutions are becoming more attractive than ever. Combined with net metering benefits and accelerated depreciation, businesses can now achieve faster ROI while reducing energy risks and carbon footprint.
As policy momentum continues, early adopters will benefit the most from falling costs and improving technology.
Key Takeaways:
Budget Gains
– Reduced duties lower solar project costs and improve investment returns
– Domestic manufacturing support strengthens India’s solar supply chain ecosystem
– Battery incentives accelerate solar-plus-storage adoption for reliable power solutions
– Policy stability encourages faster commercial and industrial solar decision-making
– Early adopters benefit from falling costs and stronger long-term energy economics
