India’s push to expand its solar energy capacity is facing major setbacks as domestic manufacturers struggle to replace Chinese imports, leading to factory shutdowns and production delays that may derail the country's 2030 renewable energy ambitions.
- Domestic solar cell shortages force factory shutdowns and production cuts.
- India depends on China for 95% of solar cell imports amid export restrictions.
- Delays and higher costs threaten India’s target of 500 GW non-fossil fuel capacity by 2030.
What happened
Since new government rules came into effect on June 1, requiring increased use of domestically sourced solar components, many Indian solar panel manufacturers have been forced to halt production. Domestic solar cell shortages have led to wait times up to eight months, causing nearly a third of small and medium panel makers to stop output entirely while others operate at reduced capacity.
These disruptions primarily affect companies that rely on procuring solar cells rather than manufacturing them in house. With limited local cell production capacity—only around 16 to 18 GW operational, compared to an installed capacity of 200 GW—manufacturers are struggling to secure sufficient parts. The gap is exacerbated by China’s curbs on solar manufacturing technology and equipment exports, restricting India’s ability to ramp up domestic cell production rapidly.
Why it matters
India aims to achieve 500 GW of non-fossil fuel energy capacity by 2030, with solar energy expected to expand from 162 GW today to over 292 GW. The current shortage of solar cells and component delays jeopardize the timely completion of solar projects, risking slower growth in renewable capacity and a greater reliance on coal and other fossil fuels to meet rising electricity demand.
The slowdown threatens thousands of jobs and investments estimated at nearly $4 billion in solar manufacturing. Higher costs due to dependence on domestic cells, which can be almost twice as expensive as those from China, may undermine the competitiveness of Indian-made solar panels and stall sustainable energy advancement at a critical time.
What to watch next
Industry experts and government officials will closely monitor domestic cell manufacturing capacity developments over the next six months, as new factories come online to alleviate shortages. However, building these advanced manufacturing facilities requires significant capital, technical partnerships, and time for commissioning, making a rapid scale-up challenging.
China’s ongoing control over solar technology exports remains a key constraint on India’s ambitions. The extent and duration of China’s export restrictions, coupled with Indian policy responses to encourage self-reliance, will be crucial factors determining how quickly India can reduce its dependence on Chinese solar cells and secure its 2030 renewable energy goals.
