Tax Benefits and Subsidies on Solar Loans in India

Switching to solar energy is not only an eco-friendly step but also a financially smart one. With rising electricity costs, the Indian government supports adoption through tax benefits and subsidies on solar loans. 

Homeowners can avail a solar loan subsidy in India on rooftop panels, businesses get incentives like accelerated depreciation and tax deductions apply on solar loan repayments. These measures make solar a practical, cost-effective long-term solution. 

Read on to understand everything step-by-step.

Government Subsidies for Solar Panels in Domestic Homes

For households, the government has introduced direct subsidies to encourage rooftop solar installations. These subsidies are available under the Rooftop Solar Programme Phase II and are credited directly to the consumer’s bank account after installation and inspection.

Solar subsidies vary depending on system size and type of installation. Below is a structured breakdown of the subsidy benefits:

• Residential Users (Up to 3 kW): Subsidies cover 40% of benchmark cost, making solar systems more affordable for small households.
• Medium Installations (3 kW – 10 kW): A 20% subsidy is provided on the benchmark cost, lowering expenses for medium-scale residential users.
• Housing Societies & Groups: Housing societies can claim subsidies for shared spaces such as corridors, lifts and water pumps under the MNRE’s rooftop solar programme.

Subsidy on Solar Panels for Commercial Use

When it comes to businesses, the approach is slightly different. There is usually no direct subsidy on solar panels for commercial use. Instead, businesses benefit from tax incentives like accelerated depreciation. Under this rule, commercial entities can depreciate up to 40% of the asset’s value in the first year, reducing taxable profits significantly.

This tax saving acts as an indirect subsidy for businesses, lowering the overall cost of ownership. For example, under accelerated depreciation benefits, a company can save up to ₹20–25 lakh per MW installation in the first year itself. For industries with high energy consumption, the financial relief from depreciation, combined with long-term savings on electricity bills, makes solar a smart business investment.

Solar Panel Tax Benefits in India

If you install solar panels using specific loan products, such as home improvement or green energy loans, the interest component may qualify for deductions under the Income Tax Act. This can help lower taxable income and reduce overall costs.

• Homeowners (Section 80C Deduction): If you are a homeowner, the principal portion of your solar loan may qualify for Section 80C deductions, subject to the overall ₹1.5 lakh annual limit.
• Businesses (Depreciation Benefits): Businesses investing in solar systems can claim accelerated depreciation on solar panels, allowing them to recover a higher portion of the asset cost in the initial years. This not only reduces taxable income but also improves long-term financial efficiency and enhances overall ROI.
• Commercial Users (GST Input Credit): Certain government-backed schemes allow commercial users to claim GST input tax credit, further reducing the overall cost burden of solar installations.

Solar Loan Tax-Deductible Benefits

If you are financing your solar panel installation through a loan, you may wonder: Is a solar loan tax-deductible? The answer is yes, partially. Here’s how:

• Principal Repayment: For individuals, principal repayment may qualify for tax deductions under Section 80C, just like a home loan.
• Interest Repayment: Many ask, is interest on a solar loan tax-deductible? In most cases, it may qualify under Section 24(b) of the Income Tax Act, but only if the loan is classified by the lender as a home improvement loan linked to a residential property. Applicability can vary by bank and loan product, so it is advisable to confirm eligibility with the lender or a tax professional.

Income Tax on Solar Power Generation

Another area that confuses many people is income tax on solar power generation. Here’s the simple explanation:

• Households: If you install solar panels for personal use at home, the savings on your electricity bill are not considered taxable income.
• Commercial Users: If a business generates income by selling surplus power back to the grid, that income is taxable. However, this is often offset by deductions from depreciation and other business expenses.

Why These Benefits Matter?

The combination of solar panel subsidies in India, tax incentives and renewable energy incentives has made solar energy more affordable for households and businesses. Without these benefits, the upfront cost of panels can feel heavy for a middle-class family. With government subsidies for solar panels in domestic homes, the payback period shortens, while businesses gain from accelerated depreciation and loan deductions.

At a larger level, such policies align with India’s renewable energy goals by reducing reliance on fossil fuels and encouraging solar adoption across both residential and commercial sectors.

Key Takeaways

Residential users get subsidies that reduce the upfront cost of rooftop solar panels, while commercial users benefit through tax breaks like accelerated depreciation and GST input credits. If panels are financed through loans, both principal and interest qualify for tax deductions. Income tax applies only when businesses earn from selling excess power, making solar loans with tax benefits a cost-saving option during installation and repayment. Over time, these factors not only provide significant solar energy cost savings but also improve the solar ROI (return on investment) by shortening the payback period and boosting long-term financial returns.

FAQs

Is there any subsidy for solar energy in India?

Yes, the Indian government provides subsidies for residential rooftop solar systems under the Rooftop Solar Programme. For homes, the subsidy can cover 20% to 40% of the system cost, depending on the capacity. Commercial entities do not receive direct subsidies but benefit from accelerated depreciation and tax incentives.

What is the tax benefit of a solar panel loan?

A solar panel loan provides tax benefits similar to a home improvement loan. The principal repayment may qualify for deductions under Section 80C, while the interest portion may be deductible under Section 24(b). This reduces your taxable income while helping you pay off the loan faster.

Are both principal and interest on a solar loan tax-deductible?

Generally, interest on solar loans is tax-deductible under renewable energy financing schemes. The principal repayment may qualify under Section 80C if the loan is categorised as a home improvement or green loan by the bank.

Is GST applicable to solar panels in India and can businesses claim input credit?

Yes. Solar panels attract 5% GST and businesses can claim input tax credit (ITC) on this amount if the system is used for commercial or industrial purposes.

Can housing societies or apartment complexes get solar subsidies?

Yes. Group housing societies and RWAs (Resident Welfare Associations) can avail subsidies for common facilities like lifts, water pumps and lighting when installing rooftop solar systems.
