Understanding Solar Power Taxes: Exemptions and Generation Levies Explained

India is aware of the geographical advantages it has to grow exponentially in the renewable energy sector, especially in solar and wind. The Indian government has left no stone unturned to bring in more investors and encourage consumers to use renewable energy.

For instance, currently, talks are going on to reduce the goods and services tax (GST) on solar devices from 12% to 5% and to also decrease the import duty on solar panels from 40% to 20%. 

However, do you know about the tax exemption for solar power in India? Yes, the Indian government has introduced several sections like Section 80-IA of the Income Tax Act, 1961 to provide accelerated depreciation and GST exemptions on solar projects.

These tax exemptions implied on the green energy for installation, usage and commercial services can be claimed by firms and individuals irrespective of the capital involved.

Let’s see how tax exemption for solar power in India works.

Tax Exemption for Solar Power in India

As disclosed above, the Income Tax Act  of 1961 provides Tax exemption for solar power under Section 80-IA. The exemptions are covered under accelerated depreciation.

Let’s first see the Accelerated depreciation rate of Solar Panels.

Accelerated depreciation rate on Solar Devices

Tax exemption for solar power in India

A solar project has several components (tangible assets) in it: devices, battery storage, panels, etc. Accelerated depreciation (AD) helps investors recover their capital invested in setting up solar projects by claiming higher solar tax depreciation on the various assets.

The rates of depreciation for the solar are given in the tangible assets section, 3-Machinery and Plant, under subsection 8. The depreciation rate for renewable energy devices is granted at 40% of the cost that occurred for any device established in AY 2018-19  onwards. However, the depreciation allowance for AYs 2003 to 2019 was 80%.

Below are the renewable energy devices covered under Ssection 8 (from point 13 onwards) for more information – 

(XIII) Renewal energy devices being—

(a)  Flat plate solar collectors

(b)  Concentrating and pipe-type solar collectors

(c)  Solar cookers

(d)  Solar water heaters and systems

(e)  Air/gas/fluid heating systems

(f)  Solar crop driers and systems

(g)  Solar refrigeration, cold storage, and air-conditioning systems

(h)  Solar steels and desalination systems

(i)  Solar power-generating systems

 (j)  Solar pumps based on solar-thermal and solar-photovoltaic conversion

(k)  Solar-photovoltaic modules and panels for water pumping and other applications 

How does Accelerated depreciation help Investors?

In the first year of inception, a company can claim up to 80% depreciation on solar panels. This helps reduce the setting-up and running costs of the solar plant in the long run, making it financially feasible and practical. With the support of the government, more and more companies are coming forward and investing in India’s solar sector. 

Tax on Solar Power Generation Systems

Suppose, a company installed a Solar Power Generation System. Then, for the first ten years, the company is exempt from paying income tax on the earnings from the solar plant. Also, the accelerated depreciation tax benefits allow the company to recover its set-up costs. 

Let’s see the subsidies provided by the government to boost the solar sector.

Solar Subsidies Given by Central and State Governments of India

Tax exemption for solar power in India

The Indian government’s Ministry of New and Renewable Energy (MNRE) has introduced various Central Financial Assistance (CFA) schemes to provide financial aid for both personal and commercial use. 

Many states including  Uttarakhand, Himachal Pradesh, Jammu & Kashmir, and Uttar Pradesh, get assistance of 70% installation cost from state governments and 30% assistance for installation cost for rooftop solar panel installations.

Schemes like Jawaharlal Nehru National Solar Mission (Phase II) under SECI help set up projects with viability gap funding support from the central government.  The projects are selected based on bidding. Any developer can participate in the open tender process announced by SECI.

So, SECI provides funding support to the project developers involved in providing solar solutions for residential or personal purposes; say to a social association. 

To ease up the process, you can avail yourself of the services of solar solution providers like Sustvest and benefit from solar energy through a PPA model or RESCO model of SECI. Under this, rooftop solar owners can use electricity and pay for it at a pre-decided monthly tariff plan. The excess electricity can be sold to the grid supplier/DISCOM for monetary benefits.

 See the subsidies provided for different types of solar projects below.

Types of Solar ProjectsSubsidy
Solar parks and Ultra-mega solar power projectsCFA of INR 2M/MW or 30% of the project cost.
