Solar is a fast-growing sector in sun-rich Gujarat, and its GST has evolved through several changes — around device rates and how turnkey EPC contracts are split between goods and service. Because these rules have moved, we always apply the current position rather than dated figures.
Rates on solar devices
Solar panels, modules and many renewable-energy devices carry a concessional GST rate that has been revised over time. The exact rate for your specific equipment depends on the current notification and the product’s classification — so we confirm the live position for what you supply rather than relying on an old figure. Correct HSN is the anchor.
EPC contracts: the goods/service split
Turnkey solar installation (EPC) is typically treated as a composite supply split between the goods (equipment) portion and the service (installation) portion, each taxed at its applicable rate under a prescribed ratio. This split is precisely where solar GST gets technical, and where errors creep into billing. We structure EPC invoicing to match the current rules.
Input credit and compliance
- Input credit on equipment and inputs, matched against GSTR-2B
- Correct treatment of subsidy-linked and net-metering projects
- Clean segregation of goods and service portions on EPC invoices
- Monthly GSTR-1 + GSTR-3B
