Composite Supply: The "Works Contract" Rule

When you sell solar panels + installation as a single bundled "turnkey solar installation" contract, it may qualify as a Works Contract under GST. Key implications:

A works contract for immovable property (rooftop solar is treated as immovable in many interpretations) attracts GST as applicable to the principal supply
If solar is the principal supply (which it is in most EPC contracts), some argue the composite rate should apply
Practical approach used by most dealers: For a supply-and-install contract, value 70% as goods at 5% and 30% as services at 18% (about 8.9% overall), as notified for solar power generating systems

This area has seen litigation and evolving rulings. Consult a CA specialising in GST before finalising your billing structure.

Input Tax Credit (ITC) for Solar Dealers

As a GST-registered solar dealer, you can claim ITC on:

Solar panels, inverters, cables purchased for resale (claim ITC at purchase, pay GST on sale)
Business expenses like vehicle fuel (limited ITC), office rent, etc.
Tools and equipment purchased for your business

ITC is not claimable by end customers (homeowners) on solar system purchases, as it is used for personal consumption (not for taxable output supply).

Billing Best Practices for Solar Dealers

Always issue GST-compliant invoices with correct HSN codes, GSTIN of buyer (if B2B), and tax breakdowns
Separate equipment and service line items on your invoice for clarity
File GSTR-1 and GSTR-3B on time — delays attract interest and late fees
Maintain purchase invoices from suppliers for ITC claims — always buy from GST-registered distributors
Check e-invoicing requirement — applicable if your annual turnover exceeds ₹5 crore (as of 2026)

GST and PM Surya Ghar Subsidy

The PM Surya Ghar subsidy is deducted from the total system cost by the government before billing the customer. Your GST invoice to the customer should be for the net amount after subsidy deduction, or alternatively, issue the invoice for the full amount and show the subsidy as a reduction — your CA should guide you on the correct treatment to avoid GST liability mismatch.
