Key Takeaways

• PM Surya Ghar Yojana provides subsidies of ₹30,000–78,000 for residential rooftop solar, but industrial/commercial projects are not eligible for this scheme.
• Industrial solar projects benefit from accelerated depreciation (40% in year 1), which effectively reduces project cost by 25–30% through tax savings.
• State-level incentives for industrial solar include subsidized land, electricity duty exemptions, and green energy certificates in states like Rajasthan, Gujarat, and Maharashtra.
• Understanding which incentives apply to your project can improve your solar ROI by 20–35%.
• Sun Wave Technologies helps industrial clients navigate subsidy applications and maximize tax benefits for solar EPC projects.

PM Surya Ghar Muft Bijli Yojana: What Is It?

PM Surya Ghar Muft Bijli Yojana (formerly PM Surya Ghar Yojana) is the Government of India's flagship rooftop solar subsidy programme launched in February 2024 with a budget of ₹75,021 Crore. The goal is to provide free electricity to 1 crore households by installing rooftop solar systems with government subsidies.

Subsidy Structure

Who Is Eligible?

• Residential consumers only — individual households with a valid electricity connection
• Grid-connected systems — off-grid systems are not eligible
• BIS-certified equipment — only ALMM-listed solar modules and BIS-certified inverters qualify
• Empanelled vendors — installation must be done by a vendor empanelled with the state DISCOM

Important: Industrial and Commercial Projects Are NOT Eligible

This is a common misconception. PM Surya Ghar Yojana subsidies are exclusively for residential consumers. Factories, warehouses, commercial buildings, and industrial units cannot claim this subsidy.

However, industrial projects have their own set of financial incentives that are often more valuable than the residential subsidy. Let's explore those.

Financial Incentives for Industrial Solar in India

1. Accelerated Depreciation (AD) — The Most Valuable Benefit

Under Section 32(1)(iia) of the Income Tax Act, solar power assets qualify for 40% accelerated depreciation in the first year of installation. This is the single most powerful financial incentive for industrial solar.

How it works:

For a 1 MW solar plant costing ₹4 Crore:

The Year 1 tax savings of ₹40 lakhs alone reduces the effective payback period by 6–8 months. The total tax benefit of ₹92+ lakhs over the depreciation period makes solar one of the most tax-efficient investments available.

Who can claim AD:

• Companies and firms with taxable profits
• The entity must own the solar system (not applicable for RESCO/OPEX — the developer claims AD in that model)
• System must be commissioned and operational in the financial year

2. Custom Duty and GST Benefits

• Solar modules: 0% GST for modules used in government projects; 12% GST for commercial procurement
• Inverters: 12% GST
• Solar cells: Basic Customs Duty (BCD) of 25% on imported cells, 40% on imported modules (driving domestic manufacturing)
• Domestic Content Requirement (DCR): Using ALMM-listed Indian modules can qualify for additional benefits in certain schemes

3. Priority Sector Lending

The Reserve Bank of India (RBI) classifies solar energy under priority sector lending:

• Banks must allocate a portion of their lending to priority sectors
• Solar projects qualify for lower interest rates (8–10% vs. 10–14% for regular term loans)
• Faster loan processing and approval
• Available from SBI, PNB, Bank of Baroda, and other major banks

4. Green Energy Open Access Benefits

For factories procuring solar through open access:

• Waiver of inter-state transmission charges for solar projects
• Reduced or zero transmission charges in many states
• Green energy certificate (REC) generation potential
• CSS waiver in group captive model

State-Level Solar Incentives for Industry

Haryana

• Electricity duty exemption: 100% exemption for solar power consumed within the state
• Net metering: Favorable net metering policy with annual credit settlement
• Industrial policy incentive: Solar installation earns points under Haryana Enterprise Promotion Policy (HEPP) for additional benefits like stamp duty concession
• DHBVN/UHBVN support: Streamlined net metering approval process

Rajasthan

• Rajasthan Investment Promotion Scheme (RIPS): Capital subsidy of 25–30% on solar investment for new industrial units
• Land allocation: Subsidized government land for solar parks
• Electricity duty: Exemption on captive solar power consumption
• Wheeling charges: Reduced wheeling charges for captive solar
• Best solar irradiance in India: 5.5–6.0 kWh/m²/day maximizes generation

Gujarat

• Gujarat Solar Power Policy: One of India's most progressive solar policies
• Industrial plot scheme: Priority allotment of industrial plots for units with solar commitment
• Net metering: Favorable policy with monthly adjustment
• Low CSS: Gujarat has the lowest cross-subsidy surcharge among major industrial states

Maharashtra

• Maharashtra Solar Policy: 100% electricity duty exemption on captive solar power
• MIDC incentives: Special incentives for solar installation in MIDC industrial areas
• Power purchase obligation (RPO): Solar installation helps meet RPO requirements, avoiding penalty
• Very high tariffs: Industrial tariffs of ₹10–13/kWh make solar savings enormous

Delhi

• Generation-Based Incentive (GBI): ₹2/kWh for solar generation (varies by consumer category)
• Net metering: Extended to 1 MW capacity
• Green building incentives: Additional FAR (Floor Area Ratio) for buildings with rooftop solar
• Highest industrial tariffs: ₹9–11/kWh ensures the best solar economics

MNRE Solar Guidelines and Policies

The Ministry of New and Renewable Energy (MNRE) sets national policy direction for solar energy:

Key MNRE Policies Affecting Industrial Solar

1. National Solar Mission: Target of 500 GW renewable energy by 2030, with 280 GW from solar
2. ALMM (Approved List of Models and Manufacturers): Only ALMM-listed modules can be used in government and subsidy-backed projects. Key Indian manufacturers on ALMM: Waaree, Adani Solar, Vikram Solar, Tata Power Solar
3. BIS Certification: Mandatory for all solar modules and inverters sold in India
4. Renewable Purchase Obligation (RPO): Industrial consumers must source a percentage of electricity from renewable sources — solar installation helps meet this obligation
5. Green Hydrogen Mission: Incentivizes solar power for hydrogen production (future industrial application)

RPO Compliance Benefits

Many industrial consumers are required to meet RPO targets:

• Current RPO target: 8–10% solar (varies by state)
• Target increasing to 25% by 2030
• Penalty for non-compliance: ₹0.5–1.0/kWh on shortfall
• Installing solar directly satisfies RPO without purchasing RECs

For a factory consuming 1 Crore units per year with 10% solar RPO:

• RPO requirement: 10 lakh solar units
• Cost of buying RECs: ₹10–20 lakhs per year
• Cost of own solar generation: ₹0 (post-payback) or ₹2.5–3.5/kWh (LCOE)
• Double benefit: Save on electricity AND avoid RPO penalties/REC purchases

Tax Planning with Industrial Solar

Optimal Tax Strategy for Solar Investment

For maximum tax benefit from industrial solar:

1. Commission before March 31: Ensure your system is commissioned before the financial year-end to claim AD in the current year
2. Choose CAPEX over RESCO: Only CAPEX (owned) systems qualify for accelerated depreciation. In RESCO, the developer claims AD
3. Structure under the right entity: Ensure the entity claiming AD has sufficient taxable profits to absorb the depreciation
4. Combine with MAT planning: If subject to Minimum Alternate Tax, AD may need different treatment — consult your CA
5. Document thoroughly: Maintain commissioning certificates, DISCOM approvals, and equipment invoices for tax audit

Solar Investment Under New Tax Regime

Under the new tax regime (lower rates, fewer deductions):

• Accelerated depreciation on solar is still available as it falls under Section 32 (business asset depreciation)
• However, the effective tax saving is lower at the reduced rate
• Consult your tax advisor to determine which regime maximizes your combined solar + tax benefit

How to Apply for Solar Incentives: Step by Step

For Accelerated Depreciation

1. Install and commission your solar system (via EPC contractor)
2. Obtain commissioning certificate from DISCOM
3. Record the solar asset in your books at actual cost
4. Claim 40% depreciation in your Income Tax Return for the year of commissioning
5. Continue claiming depreciation on Written Down Value (WDV) in subsequent years

For State Incentives

1. Check your state's industrial/solar policy for applicable incentives
2. Apply through the state industrial development corporation (e.g., HSIIDC in Haryana, RIICO in Rajasthan)
3. Submit project details, investment proof, and commissioning certificate
4. Most state incentives require application within 6–12 months of commissioning

For RPO Compliance

1. Register with your state's RPO compliance portal
2. Submit monthly/quarterly solar generation data
3. Obtain solar generation certificates from your DISCOM
4. File RPO compliance report annually

Frequently Asked Questions

Can industrial units get subsidy under PM Surya Ghar Yojana?

No. PM Surya Ghar Yojana subsidies are exclusively for residential electricity consumers. Industrial, commercial, and institutional consumers cannot claim this subsidy. However, industrial solar projects benefit from accelerated depreciation (40% in year 1), which provides tax savings of ₹25–30 per ₹100 invested — often more valuable than the residential subsidy on a per-kW basis.

What is the accelerated depreciation benefit for solar in India?

Accelerated depreciation allows you to depreciate 40% of your solar asset value in the first year itself, instead of the standard 15% rate. For a ₹4 Crore solar project with 25% corporate tax rate, this means ₹40 lakhs in tax savings in year 1 alone. The total tax benefit over the depreciation period exceeds ₹90 lakhs, effectively reducing your project cost by 23–25%.

Which solar panels qualify for government schemes in India?

Solar modules must be listed on MNRE's Approved List of Models and Manufacturers (ALMM) to qualify for government-backed schemes. Major ALMM-listed manufacturers include Waaree (India's largest), Adani Solar, Vikram Solar, Tata Power Solar, Emmvee, and Renewsys. For EPC projects, using ALMM-listed modules ensures eligibility for all current and future government incentives.

How does solar help with RPO compliance for factories?

Industrial consumers in India are required to meet Renewable Purchase Obligation (RPO) targets — currently 8–10% of total consumption must come from renewable sources. Installing rooftop solar or procuring solar through open access directly satisfies this obligation. Without solar, factories must purchase Renewable Energy Certificates (RECs) at ₹1–2 per unit, adding ₹10–20 lakhs per year for a factory consuming 1 Crore units annually.

Are there any subsidies for industrial solar in Haryana?

While there's no direct capital subsidy for industrial solar in Haryana, the state offers several benefits: 100% electricity duty exemption on captive solar power, streamlined net metering approvals through DHBVN/UHBVN, incentive points under the Haryana Enterprise Promotion Policy (HEPP), and favorable open access charges. Combined with central accelerated depreciation, these make Haryana one of the most attractive states for industrial solar investment.

Can I get a bank loan for industrial solar at preferential rates?

Yes. Solar energy qualifies as a priority sector under RBI guidelines, which means banks offer preferential lending terms. Expect interest rates of 8–10% for solar term loans from banks like SBI, PNB, and Bank of Baroda, compared to 10–14% for regular term loans. Loan tenures of 7–10 years are standard, with EMIs roughly matching your monthly electricity savings — making the investment cash-flow neutral from day one.
