Commercial Solar Loans and Commercial Solar Financing for Businesses in India

Commercial electricity consumers in India, including retail businesses, hotels, hospitals, educational institutions, and industrial facilities, pay some of the highest electricity tariffs in the country. A rooftop solar installation that offsets a significant proportion of grid consumption represents one of the highest-return capital investments available to these businesses, and commercial solar loans from specialist commercial solar financing companies make the investment accessible without requiring the full capital outlay upfront. Understanding how commercial solar financing works, what distinguishes quality commercial solar financing companies, and how the financial case for a commercial solar investment is structured helps business owners and facility managers make the right decision about solar adoption.

What is a commercial solar loan?

A commercial solar loan is a credit facility extended to a business, institution, or commercial property owner to finance the capital cost of a solar installation on a commercial or industrial property. Unlike residential solar loans, which are typically collateral-free for smaller amounts and structured around the PM-Surya Ghar subsidy framework, commercial solar loans are generally larger in amount, longer in tenure, and assessed against the commercial creditworthiness of the business and the financial case of the solar investment.

The key characteristics of commercial solar loans:

• Loan amounts: commercial solar installations typically range from Rs. 5 lakh for small commercial rooftop systems to several crore for large industrial rooftop or ground-mounted installations. Commercial solar loans are sized to the net system cost after applicable subsidies, which for commercial customers are more limited than for residential customers
• Loan tenures: commercial solar loan tenures typically range from three to ten years, with the tenure selection reflecting the business’s preference for a lower monthly EMI at longer tenure versus the lower total interest cost of a shorter tenure
• Interest rates: commercial solar loan rates from banks and NBFCs typically range from 9 to 14 per cent per annum on a reducing balance, varying with the borrower’s credit profile, the loan amount, and the lender’s product structure
• Security: larger commercial solar loans typically require some form of security, which may be the solar asset itself, a charge on the property where the system is installed, or a general corporate guarantee from the borrower’s business

What financial case supports commercial solar financing?

The financial case for commercial solar financing is based on the comparison between the cost of the loan and the electricity bill savings that the solar installation generates:

• Monthly EMI vs monthly saving: a well-structured loan for solar rooftop commercial installation produces a monthly EMI that is lower than the monthly electricity bill saving the solar system generates. This means the investment is cash-flow positive from the first month, and the solar installation effectively pays for the loan repayment from the savings it generates
• Return on investment: the internal rate of return (IRR) of a commercial solar investment in India typically ranges from 15 to 25 per cent per annum depending on the system size, the applicable tariff, the solar irradiance of the location, and the financing terms. This return compares favourably with most alternative capital investments available to commercial businesses
• Tax benefits: commercial solar installations are eligible for accelerated depreciation of 40 per cent in the year of installation under the Income Tax Act, which significantly reduces the effective post-tax cost of the investment for profitable businesses that can utilise the depreciation benefit

How do commercial solar financing companies evaluate loan applications?

Commercial solar financing companies evaluate commercial solar loan applications against a combination of the borrower’s creditworthiness and the technical and financial quality of the solar project:

• Business financials: the borrower’s revenue, profitability, existing debt service obligations, and the ability to service the proposed solar loan from operating cash flow are the primary credit assessment inputs
• Electricity bill history: the historical electricity consumption and tariff data that establishes the baseline against which the solar system’s generation and savings are projected
• Solar project assessment: the technical design of the proposed system, the credibility of the EPC contractor, and the energy yield assessment that supports the financial projections

What are the tax benefits of commercial solar financing?

Commercial solar financing is made considerably more attractive for profitable businesses by the income tax provisions for capital investment in renewable energy. Commercial solar installations are eligible for accelerated depreciation of 40 per cent under the Income Tax Act, which allows businesses to deduct 40 per cent of the system cost from taxable income in the year of installation. For a business in the 30 per cent tax bracket, this translates to an immediate tax saving of approximately 12 per cent of the system cost, significantly reducing the effective net cost of the installation. When this tax benefit is factored into the commercial solar loan financial model alongside the electricity bill savings and the depreciation over subsequent years, the IRR of a commercial solar investment in India typically reaches 18 to 25 per cent, making it one of the highest-return capital investments available to commercial businesses. Commercial solar financing companies that understand the tax dimension of the investment can help business customers structure the financing in a way that maximises this benefit alongside the energy cost saving.
