AI Summary

GST rate on solar panel supplies varies by whether installation is a composite supply or a separable service.
GST treatment depends on whether installation is provided and invoicing structure. Product-only sales attract the goods rates applicable to each item; panels typically attract a lower goods rate while other components attract the standard rate. Where panels and installation form a single supply or are invoiced together, the transaction is a composite supply and the panel's rate applies to the whole. If contractual elements are not independent, deemed valuation/apportionment rules may apply to allocate rates between goods and services, affecting the effective blended tax and ITC availability.
