Joshi cites $400 billion in renewable investment discussions and targets 100 GW of solar cell capacity by mid-2027

Pralhad Joshi put potential renewable investment discussed at the summit at about $400 billion. He projected 100 GW of domestic solar cell manufacturing capacity by May–June 2027.

India's clean-energy push produced two headline numbers at the Bharat Renewable Energy Summit & Expo 2026 in New Delhi. Union Minister for New and Renewable Energy Pralhad Joshi said the government discussed potential investments of about $400 billion in the sector, and that domestic solar cell manufacturing capacity, now about 47 GW, is set to reach 70 GW by the end of December and 100 GW by May–June 2027. Together they say a lot about where India's energy transition stands: installation is no longer the main constraint, and the race is now to make more of the hardware at home.

The summit

The four-day event, organised by the Ministry of New and Renewable Energy (MNRE), ran from 2 to 5 November 2026 at Bharat Mandapam. Prime Minister Narendra Modi inaugurated it, and participants from more than 130 countries, including over 40 ministers, attended.

In his address, the Prime Minister stressed the importance of renewable energy at a time of global energy shocks, called for more innovation in solar technology and linked the sector to the Atmanirbhar Bharat and Make in India campaigns.

Where capacity stands

Joshi said India's installed non-fossil-fuel power capacity has crossed 310 GW, up from 200 GW in September 2024. Reports from the summit put solar capacity at about 171 GW and wind at about 60 GW. Joshi also said the sector had attracted investments of $67 billion over the past two years.

The government's target is 500 GW of non-fossil capacity by 2030, so India is a little under two-thirds of the way there with just over four years to go. The pace of additions in the past two years, more than 100 GW, suggests the target is within reach if grid connections, storage and land acquisition keep up.

The $400 billion question

On 4 November, Joshi said the government had received long-term investment commitments of around $400 billion from companies at the summit. He described the number as a preliminary estimate and said a detailed breakdown would follow.

The commitments reportedly cover renewable generation, energy storage, transmission, green hydrogen and manufacturing. Joshi's figure is roughly double the investment the government estimates is needed to meet its 2030 goals, which reports put at about $220 billion.

Pledges at investor summits do not all turn into projects, and some will overlap with announcements already made. Still, the size of the number reflects how much capital is now looking at Indian clean energy, from developers and manufacturers to storage and hydrogen players.

The solar cell gap

The more concrete story may be in manufacturing. India has built an enormous solar module industry in a short time. MNRE’s summit release reported 225 GW of module manufacturing capacity and 45 GW of cell manufacturing capacity. Business Standard reported Joshi’s later cell estimate at 47 GW.

But modules are only the last step of the solar supply chain. The most technically demanding stages are upstream: purifying polysilicon, slicing it into wafers and turning wafers into cells. Here India has lagged. Cell capacity is about 47 GW today, far below module capacity, which means many Indian-assembled modules still use imported cells, most of them from China.

Joshi said cell capacity will reach 70 GW by 31 December 2026, a figure he said cell manufacturers have committed to, and 100 GW by May–June 2027. He also said the government was considering whether to extend beyond 31 December a relaxation of the domestic solar cell sourcing requirement, and would decide within about 10 days.

Why cells matter

Solar cells are where much of the technology and value in a panel sit. Newer cell designs, such as TOPCon and heterojunction, are where efficiency gains come from, and manufacturing them requires precise, high-volume processes and equipment. Building cell capacity at home means India captures more of the value from its own solar build-out, reduces exposure to supply shocks and trade disputes, and develops the engineering skills needed to move further upstream into wafers and polysilicon.

Several large Indian manufacturers have announced or are building multi-gigawatt cell factories, and the government has been working on support for the remaining upstream gaps. Closing the gap between module and cell capacity is therefore one of the most important industrial goals in India's energy transition.

For manufacturers, the message from the summit is that demand is unlikely to be the problem. A pipeline of renewable projects large enough to add close to 200 GW more by 2030, combined with government rules that favour domestically made equipment in many projects, gives cell makers the visibility they need to commit capital to factories that take years to build and pay back. The open question is how quickly they can add equipment, train workers and reach the yields and efficiencies of established overseas producers.

What it means for India and beyond

For India, a fully domestic solar supply chain would strengthen energy security and create manufacturing jobs, while supporting a power system increasingly built on renewables. For the rest of the world, a large Indian solar manufacturing base offers an alternative source of panels and cells at a time when many countries want to diversify their supply away from a single dominant producer.

What to watch

The key numbers to track in the coming months are whether cell capacity actually reaches 70 GW by the end of the year, what the government decides on the domestic sourcing relaxation, and how much of the $400 billion in pledges turns into specific projects. Progress on storage and transmission, which will determine how much renewable power the grid can absorb, will matter just as much.
