Solar Panel GST Rate in India: HSN Code & Slabs
Most buyers assume solar panels carry the same GST rate as other electronics, somewhere around 18%. That assumption is wrong and it's the single most common misconception in solar procurement conversations. The solar panel GST rate in India is 5%, a concessional rate specifically applied to renewable energy devices, and it was previously 12% before being revised downward.
At a Glance: Solar GST Rates and HSN Codes
Product/Service | HSN Code | GST Rate |
|---|---|---|
Solar panels/modules | 8541 40 11 / 8541 40 12 | 5% |
Solar inverters | 8504 | 5% |
Solar EPC contracts (goods + services) | 9954, 9983, 9987 | Blended: 70% @ 5% + 30% @ 18% |
Why People Get the Solar Panel GST Rate Wrong
The confusion has a specific source: solar installation services and solar panels are not taxed identically, and most people conflate the two into one number. The panel itself, classified under HSN 8541 40 11, sits at the concessional 5% rate because it's officially a "device for generating electricity from renewable sources." But when a full EPC (Engineering, Procurement, Construction) contract is billed, meaning the panel plus labour plus installation as one bundled service, the tax treatment splits.
Under the standard valuation rule for solar EPC contracts, 70% of the contract value is treated as "goods" and taxed at 5%, while the remaining 30% is treated as "services" and taxed at 18%. Blend those together and the effective rate on a full EPC invoice lands closer to 8.9%, not 5%, and definitely not 12% or 18% flat. This blended figure is what actually shows up on most residential and commercial solar invoices, and it's rarely explained by installers upfront. It's also already folded into the pricing you'll see in our 1kW solar panel price in India guide, so you won't see it as a separate line item unless you ask.
Solar Panel HSN Code: The Full Breakdown
Component | HSN Code | GST Rate | Notes |
|---|---|---|---|
Solar PV modules/panels | 8541 40 11 | 5% | Core renewable energy device classification |
Solar cells | 8541 40 12 | 5% | Sub-component, same concessional treatment |
Solar inverters | 8504 | 5% | Converts DC to usable AC power |
Mounting structures | Varies (often 18%) | 18% | Frequently taxed as general metal fabrication, not a renewable device, verify at publish with your vendor's invoice |
Batteries (for hybrid/off-grid) | 8507 | 18% or 28% depending on chemistry | Not covered under the concessional solar rate |
This is the fact most commercial solar sales pages leave out entirely: not every component in your quote is taxed at 5%. Mounting structures and batteries often carry the standard 18% or higher rate, which is why a full system invoice rarely nets out to a clean 5% even though "solar panels are 5% GST" is technically true for the panel line item alone.
The Rate Change History: 12% to 5%
Solar panels and renewable energy devices were previously taxed at 12% GST. The rate was revised down to the current concessional 5% to encourage renewable adoption, though the exact notification date isn't consistently cited across sources, so confirm the applicable rate on your invoice date directly with your CA or the current GST notification before filing (verify at publish).
GST Input Tax Credit: What Businesses Should Know
For commercial and industrial buyers, GST paid on solar panel purchases is generally eligible for Input Tax Credit (ITC) if the system is used for business purposes, which materially improves the effective cost compared to residential purchases where ITC doesn't apply. This is a meaningful, and often overlooked, difference between residential and C&I solar economics.
Pros and Cons of the Current GST Structure
Pros:
- 5% concessional rate on panels genuinely lowers the barrier to entry compared to standard 18% goods
- Businesses can claim ITC, improving payback economics for commercial installations
- Encourages domestic renewable adoption in line with national solar targets
Cons:
- The blended 70:30 EPC valuation rule means the "5%" headline rate is misleading for full-system buyers
- Ancillary components (structures, batteries) are taxed at standard rates, inflating the effective blended rate
- Rate history and effective dates are inconsistently documented across sources, creating compliance risk for businesses filing returns
Who Benefits Most from the Current GST Rate
Strong fit: commercial and industrial buyers who can claim ITC, since the net effective cost after credit is meaningfully lower than the invoice price, especially at the scale discussed in our 2 MW solar power plant cost guide.
Marginal fit: residential buyers purchasing a full EPC-bundled system, where the blended 8.9% effective rate applies and no ITC offset exists.
Not a fit for assuming savings: anyone buying batteries or premium mounting structures expecting the 5% rate to apply uniformly. It doesn't, and budgeting on that assumption will produce a cost surprise at invoicing.
How to Verify the GST on Your Solar Quote
- Ask your vendor to itemise the invoice by HSN code rather than showing one blended total.
- Confirm the panel line item is billed under HSN 8541 40 11/12 at 5%.
- Check whether the quote is a pure supply (5% on goods) or an EPC bundle (70:30 blended valuation).
- For business purchases, confirm ITC eligibility with your accountant before finalising.
- Cross-check the current notification rate with the GST portal or your CA, since renewable energy GST rates have changed before and can change again.
FAQs
What is the GST rate on solar panels in India?
The solar panel GST rate in India is 5%, classified under HSN code 8541 40 11/12, down from a previous 12% rate.
What is the HSN code for solar panels?
Solar panels/modules fall under HSN 8541 40 11, and solar cells under 8541 40 12, both taxed at 5% GST.
Is GST on solar installation different from GST on solar panels?
Yes. Full EPC (installation) contracts use a blended valuation of 70% goods at 5% plus 30% services at 18%, producing an effective rate closer to 8.9%, higher than the 5% rate on panels alone.
What GST rate applies to solar inverters?
Solar inverters fall under HSN 8504 and are taxed at 5%, the same concessional rate as panels.
Are solar batteries taxed at the same GST rate as panels?
No. Batteries typically fall under HSN 8507 and are taxed at 18% or 28% depending on chemistry, not the 5% concessional solar rate.
Can businesses claim Input Tax Credit on solar panel GST?
Yes, businesses purchasing solar systems for commercial use can generally claim ITC on the GST paid, improving effective project economics. Residential buyers cannot claim ITC.
Was the GST rate on solar panels always 5%?
No, the rate was previously 12% before being revised down to the current concessional 5% rate to support renewable adoption. Confirm the applicable rate for your invoice date with current GST notifications.
Why does my solar invoice not show a flat 5% GST?
Because mounting structures, batteries, and bundled EPC services are taxed at different rates (often 18%), your blended invoice total will be higher than the 5% panel-only rate suggests.
