Top Things to Know About Commercial Solar Financing


Setting up a solar project can cost up to INR 6 Crores / MW, and most of it comes from equity and debt financing. Equity financing is the process of raising money from internal stakeholders in the company or other investors. In contrast, debt financing—which is about 70% of the project cost—comes in the form of a loan taken out against collateral. 

As a result, before a company decides to set up a solar power project, it is vital to learn about commercial solar financing options.

Here, We have Attempted to Answer Basic Questions, Like:

  • How are commercial solar projects financed?
  • What is the best way to finance solar?
  • How many years can you finance solar panels?

First, let us figure out how many options are there to finance a commercial solar company project.

Domestic Funding from Banks 

Local banks have consistently been the largest financiers of commercial solar projects in India. Banks offer a low interest rate of 11-13%, but they may ask for collateral of up to 100% of the loan amount. 

These institutions started with loans for 7-10 years. However, they are now comfortable with lending for up to 15 years, thanks to the enormous regulatory burden and the formalities companies need to finish before they can begin the solar project.

NBFC Financing

NBFCs/Non-Banking Financial Institutions, such as the Indian Renewable Energy Development Agency Limited (IREDA), are ready to offer low-interest loans for commercial solar projects. For example, grid-connected solar PV projects can get loans with interest rates of 10.2 to 11.4%, depending on the grade that the authorities give to the solar project. 

It is worth mentioning that IREDA gives out loans for projects with a minimum debt requirement of INR 50 lakhs and ones that are commercially and technically viable. The best part of the IREDA loan is that commercial solar projects can get it with collateral of just 10-33% of the total amount applied for.
