ISMA's Vision 2047 targets 32.3 lakh solar jobs and USD 89 billion in investment

For Indian manufacturers and investors, the report is a benchmark. It is not a forecast. Moving into cells, wafers and polysilicon would cut import dependence. It would also push jobs up the value chain. Two things remain unknown: which projects get financed, and how fast global demand absorbs the extra capacity.

The 2047 numbers

The report is Vision 2047: Solar Manufacturing from Polysilicon to Power Plant. It projects 2,275 GW of installed solar capacity by 2047. That would need 3,266 GW of module capacity, 2,796 GW of cells, 2,479 GW of ingots and wafers and 2,156 GW equivalent of polysilicon. Manufacturing jobs would rise from about 4.1 lakh now to 8.1 lakh by 2030 and 32.3 lakh by 2047. Direct plant jobs would climb from about 1.4 lakh to 11.1 lakh. Nearly 68% of them would be in cells, wafers and polysilicon. ISMA also projects India at 26.5% of global module supply by 2047. That compares with around 5.9% under current policy by 2030.

Cell plants first

Rayzon Solar is a Gujarat-based module maker. It starts production at its 5.1 GW TOPCon cell facility in December 2026. First deliveries are due in the first quarter of 2027. Rayzon has 11.3 GW of installed module capacity. It plans a 5.1 GW ingot casting and wafer slicing plant by 2028. It is negotiating incentives with several states. It also shifted from IPO proceeds to debt financing amid market volatility. That makes the upstream leg a credit question as much as a policy one. Co-founder Chirag Nakrani said the cell plant would mark an important milestone in Rayzon Solar's push towards deeper backward integration.

Waaree Energies is taking a similar route. It is doing so at home and in the United States.

Its subsidiary Waaree Solar Americas began commercial production on two 800 MW module lines at Brookshire, Texas, on 29 October. That doubled the site to 3.2 GW. Waaree Energies plans to raise its India cell capacity from 5.4 GW to 15.4 GW in fiscal 2027. It also plans a 10 GW ingot and wafer facility. That facility is due in fiscal 2028. US manufacturing revenue reached INR 13 billion ($146 million) in the second quarter of fiscal 2027. That was up from INR 7.32 billion a year earlier.

Equipment and engineering

Factories need more than money. They need the engineering between an equipment order and a line running at spec.

Zuvay Technologies says it combines wafer and cell-line configuration with GW-scale cell plant engineering. It also covers automation, utilities, cleanroom, HVAC and gas abatement. Its parametric tools derive utility loads and cost of production from cell-line capacity and equipment class. By 2030 it aims to be the go-to engineering and equipment partner for India's GW-scale solar manufacturing. It also aims to build semiconductor capabilities. ISMA's report calls for domestic manufacturing equipment and stronger technical skills.

Money and policy

ISMA puts the investment bill at about USD 4.3 billion a year between 2027 and 2047. Nearly 70% would go to polysilicon, wafers and cells.

The Production Linked Incentive scheme had drawn about USD 8.4 billion of investment by June 2026, the report says. Every dollar of incentive attracted around four dollars of private capital. ISMA projects the annual solar import bill falling from about USD 4.4 billion to zero by 2041. Its policy checklist is where the plan becomes a schedule. It includes firm ALMM timelines, completed PLI projects, wider rooftop and agricultural solarisation and faster upstream investment.

What to watch

Amit Manohar is secretary general of ISMA. He said the ambition "will require sustained policy support, a predictable demand pipeline, investments in upstream manufacturing and continued efforts to strengthen India's global competitiveness".

Waaree's global module order book exceeds 25 GW. Its US domestic business accounted for 43.8% of its INR 592 billion order book. That was up from about 36% at the end of the previous quarter. Sunil Rathi, a director of Waaree Group, said shifting trade policy had strengthened the case for local manufacturing. Rayzon's December commissioning will be the first clear test. It will show whether India's cell capacity arrives when companies say it will.
