Financing is one of the most common barriers MSMEs cite when evaluating solar investment. The good news: the solar lending ecosystem in India has matured significantly in 2025–26, with multiple institutional lenders offering dedicated green energy products at attractive rates. This guide compares the main financing options available to MSMEs in Hyderabad and across Telangana/AP.
SIDBI — Small Industries Development Bank of India
SIDBI has dedicated green energy lending lines specifically for MSMEs, typically channelled through its direct lending or refinancing schemes. SIDBI's solar loans offer: interest rates in the range of 8–10% p.a. for eligible MSMEs; tenures up to 7–10 years; loan amounts from ₹25 lakh to ₹10 crore for individual projects; and credit guarantee support through the CGTMSE (Credit Guarantee Fund Trust for Micro and Small Enterprises) scheme for loans up to ₹2 crore, reducing or eliminating collateral requirements for eligible borrowers.
SIDBI also operates dedicated lines of credit in partnership with international development finance institutions (ADB, KfW) specifically for clean energy MSMEs. These blended finance lines can carry rates 50–100 basis points below SIDBI's standard green energy rates.
SBI — Green Loan for Industry
State Bank of India offers solar loans under its SME Energy Saver and Green Plus product lines. Key parameters: interest rates at MCLR + 50–100 bps (approximately 9–10% p.a. as of mid-2026); tenures up to 7 years; no processing fee for loans to existing SBI current account holders; solar asset as primary collateral (no additional property collateral for systems up to ₹1 crore, subject to credit assessment). SBI's relationship banking advantage is that existing current/OD account holders can often access faster processing and preferential rates.
HDFC Bank — Solar Loan Products
HDFC Bank offers solar financing through its working capital and term loan products for SMEs. Rates are typically 10–11% p.a. — slightly higher than SIDBI or SBI but with faster processing (approvals often within 5–7 business days) and more flexible documentation requirements. HDFC also offers a solar loan top-up on existing HDFC property-backed loans — an option for business owners who already have HDFC property mortgage facilities.
IREDA — Indian Renewable Energy Development Agency
IREDA is the dedicated central government financing agency for renewable energy projects. IREDA's rates for rooftop solar projects typically range from 8–9% p.a. for corporate borrowers to 9–10.5% for MSMEs, with tenures up to 15 years for larger projects. IREDA financing is particularly attractive for projects above ₹2 crore, where the longer tenure reduces annual EMI burden and the rate is competitive with private sector banks.

We prepare the loan application dossier — project report, PVsyst simulation, financial projections, and technical documentation — and liaise directly with the lender's processing team to ensure fast approvals. For most MSMEs in the ₹25 lakh–₹2 crore project range, the SIDBI CGTMSE-backed product is our first recommendation given the collateral-free feature and competitive rates.
