GST on Solar Panels

GST on solar panels in India is 5% on photovoltaic (PV) modules, as revised by the GST Council in September 2025, reducing the earlier rate from 12% to support renewable energy adoption. This applies to rooftop solar systems, ground-mounted installations, and clean technology projects used for electricity saving in homes and businesses. When you invest in solar, the solar system GST depends on whether components are supplied individually or as a complete system. Understanding GST on PV modules, solar installation GST, and component-level taxation helps you plan costs and evaluate benefits under government subsidies and green energy policy.

GST Rate on Solar Panels at a Glance

GST on solar systems varies based on classification and supply structure.
This structure defines how renewable energy GST applies across equipment and services.
GST rate on solar panel (PV modules): 5% (reduced from 12%)

Solar system GST (composite supply):

  • 70% value taxed at 5%
  • 30% value taxed at 18% (as per CBIC clarification on EPC contracts)
Solar installation GST: 18%

Solar inverter GST:

  • 5% when supplied as part of a solar power system
  • 18% when sold separately under HSN 8504

  3. What It Means for You

    1. Reduced rate lowers equipment cost
    2. Depends on bundled vs standalone supply
    3. Blended GST based on composite supply
    4. Labour increases total project cost

What the Rate Means for Your Purchase Cost

GST affects your total solar investment depending on supply structure. If a solar system costs ₹48,000, the effective solar energy tax under composite supply is approximately ₹4,272, making the total ₹52,272. This excludes approvals, maintenance, and subsidy adjustments. For rooftop solar tax planning, understanding this structure helps estimate your actual cost accurately.

GST on Solar Panel Parts and Accessories

GST on components depends on classification and billing.
If components are billed separately, individual GST rates apply. If supplied as a complete solar system, composite GST rules may apply instead.
Solar inverter GST: 5% (if bundled), 18% (if standalone)
Mounting structures:18%
Batteries:18%
Electrical components:18%

How to Calculate GST on Solar Panels

GST calculation depends on how the solar system is supplied.

For standalone panels:

Total = Base Price × (1 + 0.05)

For complete systems (composite supply):

Total GST = (70% × 5%) + (30% × 18%)

Example:

₹48,000 system → approximately ₹52,272 after GST

This helps ensure accurate solar system GST estimation.

Impact of GST on Solar Panel Prices

GST plays a key role in renewable energy adoption.
This balance improves affordability across residential and commercial use.
Reduction from 12% to 5% lowers upfront cost
Higher GST on services increases installation expense
Composite taxation standardises pricing across suppliers
Supports electricity saving and clean technology adoption

Input Tax Credit (ITC) on Solar Panels

ITC on solar systems is available under specific conditions.
ITC is not available for personal residential use, which affects rooftop solar tax outcomes for individuals.
Available for business use and taxable supply
Applies to both equipment and installation services
Requires GST registration

GST Benefits for Solar Panel Buyers

The GST framework supports renewable energy adoption.
This makes solar a cost-effective long-term solution.
Reduced 5% GST lowers upfront investment
ITC helps businesses reduce effective cost
Works alongside government subsidies and PV subsidy rules
Encourages green homes and sustainable infrastructure

Why GST Matters for Your Solar Panel Purchase

GST forms a noticeable part of your solar investment.

Before purchasing, you should:
This helps you optimise cost and planning.
Check whether supply is composite or itemised
Review GST breakup across components
Verify eligibility under government subsidies
Calculate total cost including installation and approvals

GST Reforms 2.0 on Solar Panel Types

The September 2025 update by the GST Council reduced GST on renewable energy devices, including solar panels, from 12% to 5%. This change strengthens India’s renewable transition by improving affordability and accelerating adoption of clean technology across residential and commercial sectors.

Additional Costs to Consider

GST is only one part of your total solar system cost.
You should include these when estimating total investment.
Installation and service charges (18% GST)
Net metering and approval fees
Maintenance and servicing costs
Documentation and subsidy processing charges
