Solar photovoltaic (PV) systems have emerged as a pivotal technology in the global shift towards sustainable energy solutions. Central to the widespread adoption of solar PV systems are the financial incentives provided by governments worldwide. These incentives, including tax credits, rebates, subsidies, and other support mechanisms, play a crucial role in making solar energy more affordable and attractive to consumers and businesses alike. In India, various government programs offer tax credits, rebates, and subsidies to promote the use of solar energy. This article provides a detailed examination of the financial incentives available for solar PV installations in India, comparing them with similar programs in leading countries across different continents.
Financial Incentives in India
- Subsidies and Grants
- MNRE Subsidy: The Ministry of New and Renewable Energy (MNRE) in India offers subsidies for residential rooftop solar PV systems. As of recent schemes, the subsidy can cover up to 40% of the benchmark cost for systems up to 3 kW and up to 20% for systems between 3 kW and 10 kW. However, commercial and industrial installations typically do not qualify for these subsidies.
- State-Level Incentives: Several Indian states provide additional subsidies on top of the MNRE subsidy. States like Gujarat, Maharashtra, and Rajasthan have their own incentive programs to encourage solar PV adoption. These subsidies vary in amount and eligibility criteria, contributing to a diverse landscape of support across the country.
- Tax Benefits
- Accelerated Depreciation: Businesses investing in solar PV systems can benefit from accelerated depreciation, allowing them to write off up to 40% of the project cost in the first year. This depreciation benefit reduces taxable income, thereby lowering the overall tax liability for businesses.
- Customs and Excise Duty Exemption: Imported solar PV equipment is exempt from customs and excise duties, making it more cost-effective to procure high-quality components for installations in India.
- Net Metering and Feed-in Tariffs
- Net Metering: The net metering policy allows solar PV system owners to offset their electricity bills by exporting surplus electricity to the grid. States like Karnataka, Tamil Nadu, and Delhi have implemented robust net metering policies, although specifics such as tariff rates and limits on system size vary by state.
- Feed-in Tariffs (FiTs): While less common in India today, some states have experimented with FiT mechanisms where solar PV system owners are paid a fixed rate per kWh of electricity fed into the grid. These rates are typically set by state electricity regulatory commissions. States like Karnataka's KERC (Karnataka Electricity Regulatory Commission), Tamil Nadu's TANGEDCO (Tamil Nadu Generation and Distribution Corporation), Andhra Pradesh, Telangana's TSERC (Telangana State Electricity Regulatory Commission), Rajasthan's RERC (Rajasthan Electricity Regulatory Commission) and Gujarat have either already implemented Feed-in-Tariffs or are planning to implement it in near future.
- Solar Renewable Energy Certificates (SRECs)
- Trading SRECs: Solar PV system owners can generate SRECs based on the renewable energy they produce. These certificates can be traded on exchanges, providing an additional revenue stream separate from electricity sales. The effectiveness of the SREC market in India varies by state and market conditions.
Comparative Analysis with other Countries

- Grants and Low-Interest Loans: The KfW Development Bank offers low-interest loans and grants for renewable energy projects, including solar PV installations.
- China
- Subsidies and Grants: China provides substantial subsidies and grants for both residential and commercial solar PV installations.
- Feed-in Tariffs (FiTs): China’s FiT program has been a significant driver of its solar PV market, though the rates have been gradually decreasing.
- Solar Poverty Alleviation Program: This unique program focuses on installing solar PV systems in poor regions to generate income for local communities.
- Australia
- Small-Scale Renewable Energy Scheme (SRES): This program provides financial incentives in the form of Small-scale Technology Certificates (STCs), which can be traded for cash or discounts on the installation cost.
- State Rebates and Loans: Various Australian states offer additional rebates and low-interest loans to support solar PV installations.

The kind of potential India has, in terms of available solar capacity, a push to realize the renewable energy goal of 500 GW by 2030 can easily be achieved if the various state, UT and the central governments could ease up the norms, incorporate easy financing options for the retail electricity consumers to get solar PV systems installed. The benefits like subsidies, net metering, etc, are good steps, but, do not really incentivize the end users for the huge upfront monetary investment they are expected to make to get the system installed. Subsidies are capped for residential consumers only, that too upto a maximum limit of ₹78,000, discourages consumers wanting to get higher capacity systems installed. Moreover, subsidies are available for on-grid SPV systems only. The other system types including off-grid and hybrid SPV systems have been kept out of the ambit of the Solar PV subsidy. Batteries and battery packs are an essential component when an end user intends to make a huge investment like this. They also want themselves to be somewhat self sufficient and independent of the electricity grid, and autonomy requires incorporation of batteries in the system. Some amount of tweaking up needs to be done to improve the adoption of solar PV technologies.
The government has mandated the use of Made in India components, installation by empanelled vendors, each of which needs to get a separate empanelment done for each electricity DISCOM in a state. For example, Delhi is supplied electricity by four different DISCOMS - BSES Rajdhani, BSES Yamuna, Tata Power Delhi Distribution Limited (TPDDL), and North Delhi Power Limited. If a company wants to provide solar PV installation services and wants to enable its consumers to take advantage of the rooftop solar subsidy programmes, they need to get themselves registered with 4 different DISCOMS to be able to provide their services across Delhi. Other states also have similar setups for DISCOMS. Uttar Pradesh, for example, is supplied by five distinct DISCOMS - DVVNL (Dakshinanchal Vidyut Vitaran Nigam Limited), KESKO (Kanpur Electricity Supply Company Limited), MVVNL (Madhyanchal Vidyut Vitran Nigam Limited), PuVVNL (Purvanchal Vidyut Vitran Nigam Limited) and PVVNL (Paschimanchal Vidyut Vitran Nigam Limited). Getting registered with all the different DISCOMS, providing them with the stipulated bank guarantees to be able to provide solar PV installation services could be quite bothersome for the financial health of most of the companies, which are operating in cut-throat competition with low permeability and adoption of rooftop SPV, mostly owing to huge upfront costs involved.
Financial incentives are instrumental in driving the adoption of solar PV systems worldwide, including in India. While India offers a range of incentives such as subsidies, tax benefits, net metering, and exemptions, there is room for improvement in consistency and clarity across states. Comparative analysis with global practices reveals that countries like the United States, Germany, and China have adopted diverse and evolving incentive structures that have propelled their solar PV markets forward. By learning from global best practices and continuously refining its incentive programs, India can accelerate its transition towards a sustainable energy future powered by solar PV technology.
