Best Solar Energy Stocks in India

(The stocks mentioned in the blog are based on Market Capitalisation)

India has great potential for generating solar energy. With around 300 days of sunshine annually, the country could harness solar power equivalent to 748 GW.

India's solar energy sector has grown significantly in recent years, driven by falling solar panel prices, supportive government policies, and increased environmental awareness. Moreover, the country aims to become a key net exporter of solar energy by 2026.

Solar Energy Industry in India - A Brief Overview

India produces around 5,000 trillion kWh of solar energy, from which most parts of the country receive 4-7 kWh per square metre per day. Solar power plants in India can generate energy on a distributed basis, enabling additional capacity to be added with short lead times.

In recent years, the decentralised and distributed applications of solar energy have benefited millions of people in rural Indian villages, fulfilling their cooking, lighting, and other energy needs in an environmentally friendly manner. It has led to various social and economic benefits, such as reduced risk of lung and eye ailments.

Additionally, the solar energy sector in India has become a significant contributor to grid-connected power generation capacity, aligning with the government's agenda for sustainable growth and enhancing energy security.

The Indian government has introduced schemes such as the Production Linked Incentive (PLI) and the Solar Park Scheme to create a conducive environment for solar power development and boost domestic manufacturing. These initiatives aim to achieve economies of scale, make solar energy more affordable and generate employment opportunities. 

India’s installed solar energy capacity (cumulative) touched 105.65 GW by 31st March, 2025, while a record addition of 23.83 GW in solar capacity was seen in FY2024-25, higher than 15.03 GW added in the previous fiscal. By the end of FY25, ground-mounted and rooftop solar stood at 81.01 GW and 17.02 GW, respectively, while off-grid systems accounted for 4.74 GW.

The PM Surya Ghar Muft Bijli Yojana was launched in February 2024 and has encouraged faster adoption of rooftop solar energy. India is reportedly on track to add about 41-45 GW of new solar capacity in FY26, while the first nine months of FY26 saw 30.16 GW of new capacity added. Domestic solar module production capacity under ALMM touched 144 GW per annum in late 2025. Rajasthan leads in capacity, along with Gujarat and then Karnataka. 

The Government is also aiming for 1 crore rooftop solar installations by FY2026-27 under the PM Surya Ghar target. The rapid growth is backing the country’s larger Panchamrit target of 500 GW of non-fossil energy capacity by2030.
