solar project financing

The Indian government is actively promoting its citizens’ adoption of solar energy. To make it easier for people to embrace solar energy, public sector and private banks have been instructed by the Ministry of Finance to offer loans at reasonable costs, following the guidelines set by the Government of India and the Reserve Bank of India. Installing solar energy systems has numerous advantages, including reducing pollution, decreasing reliance on the electrical grid, and lowering electricity bills. However, many individuals need more time to switch to solar energy due to the upfront installation costs. While the investment pays for itself within 3-4 years, not everyone can afford the total cost upfront. If the large lump sum payment is a concern, this is where solar project financing comes into play. Continue reading this article to find essential information about solar project financing and its benefits.

Current Scenario in India

In terms of the market, India’s renewable energy sector is the fourth most attractive market in the world. As of 2019, India ranked fifth in wind power, fifth in solar power, and fourth in overall renewable power capacity. The sector has become attractive to investors due to government support and improved economics. Renewable energy will be crucial in meeting its energy demand independently, which is expected to reach 15,820 TWh by 2040. By 2030, the government plans to establish a renewable energy capacity of 523 GW, including 73 GW from hydro sources.

Financing Structure of solar project financing

Equity Financing

Regarding the structure of solar project financing, the equity portion of the investment can come from the developer or equity partners who agree to purchase the projects. Equity partners can be individual firms, developers, equity funds managed by management firms, bank equity fund managers, or pension fund managers. These equity funds can be used as the initial capital for project construction following the completion of design, environmental studies, legal analysis, permit applications, and grid connection applications. Equity represents around 15-30% of the total project investment cost.

Debt Financing

The debt portion of the investment is typically provided by an investment bank, offering project finance or leasing finance. Debt financing constitutes the more significant portion of the investment, typically ranging from 70% to 85% of the total project cost. Large corporations and utilities may develop solar plants using their own funds without the need for project finance, utilizing their corporate balance sheets. However, they still conduct due diligence reviews before committing funds to the project.

Major Solar Project Financing Institutes in India

Major solar project financing institutes in India are as follows:

  • Indian Public Sector and Private Banks: State Bank of India (SBI), Punjab National Bank, Bank of Baroda, Central Bank, ICICI, Yes Bank, Axis Bank.

Due Diligence

Whether it is a solar, hydrogen,wind or any other type of technology, due diligence is essential for the legal, technical and financial auditing of renewable energy projects. It allows the developers, owners, investors, financial institutions, etc., who are involved in a transaction to assess the risk involved in each investment.The following are the factors considered during the due diligence phase in the case of solar project financing:

  • Legal due diligence assesses permits and contracts.
  • Insurance due diligence examines insurance policies and coverage gaps.
  • Technical due diligence evaluates the technology, integration, and technical aspects of permits and contracts.

Technical Due Diligence Assessment Areas:

  • Sizing of the PV plant, layout, PV modules, mounting or trackers, and inverters.
  • Electrical design layout, sizing, cable losses, cable placement, connectors, earthing, and protection systems.
  • Technology review of major components, including suitability, integration, track record, quality, compliance, warranties, and design life.
  • Energy yield assessments, considering assumptions, solar irradiation data, shade, degradation, uncertainty analysis, and performance ratio.
  • Contract assessments, identifying risks, construction timelines, warranty and guarantee positions, and financial model assumptions.

Developer’s Effort and Requirements:

  • Considerable effort is required to meet lenders’ requirements during the due diligence process.
  • Realistic financial models with contingencies and a sensible construction program are essential.
  • The process may identify risks and require design or component usage changes to make the project “bankable” for lenders.


The government is dedicated to increasing the utilization of clean energy sources and is already engaged in various large-scale sustainable power projects while actively promoting green energy. Moreover, renewable energy has the potential to generate numerous employment opportunities, particularly in rural areas. Additionally, there are plans to establish around 5,000 Compressed Biogas plants across the country by 2023. Projects concerned about solar project financing and its criteria must seek expert consultation in order to get the above-mentioned government scheme benefits and to complete the documentation and other procedural legalities in a hassle-free method.
