India’s solar manufacturing industry is exploring German technology and equipment suppliers as companies seek alternatives to Chinese machinery following Beijing’s proposed restrictions on solar manufacturing technology exports. Indian manufacturers are concerned that the proposed controls could disrupt plans to expand domestic production of solar wafers, ingots, polysilicon and advanced solar cells.
Companies are evaluating European suppliers, including Germany-based Centrotherm and RENA Technologies, as part of efforts to diversify their technology partnerships. However, shifting away from Chinese equipment could increase manufacturing costs by 40%–50% and extend project timelines. The development comes as India targets approximately 100 gigawatts (GW) of upstream solar manufacturing capacity by the end of the decade.
Why India Is Looking Beyond China for Solar Technology
China dominates several stages of the global solar manufacturing supply chain, particularly the production of polysilicon, silicon ingots, wafers and solar cells.
Indian manufacturers have expanded their solar module production capacity significantly over recent years. However, the country remains dependent on imported technology, machinery and intermediate components for deeper stages of solar manufacturing.
China’s proposed export restrictions have exposed this dependence and prompted Indian companies to reconsider their sourcing strategies.
According to industry representatives cited by Mint, manufacturers are exploring equipment and technology partnerships with suppliers in Germany and other European countries, Japan and Taiwan.
Germany has become an important alternative because of its established capabilities in precision engineering, industrial machinery and solar manufacturing technology.
Vineet Mittal, chairman of Avaada Group, said the company was exploring opportunities across European technology ecosystems, including equipment manufacturers and research institutions such as Fraunhofer ISE.
The objective is to reduce reliance on a single country for critical manufacturing equipment and technical expertise.
China Proposes Restrictions on 12 Solar Manufacturing Technologies
The shift towards German suppliers follows China’s October 16, 2026, announcement proposing changes to its catalogue of technologies prohibited or restricted from export.
The proposal covers 12 photovoltaic manufacturing technologies and associated equipment used in producing polysilicon, silicon wafers and advanced solar cells.
The proposed restrictions cover technologies associated with:
- Polysilicon manufacturing processes
- Advanced silicon wafer production
- TOPCon solar cell manufacturing
- Heterojunction (HJT) technology
- Back-contact solar cell technology
- Perovskite and tandem solar cells
- Advanced crystal-pulling and wafer-cutting equipment
The proposed framework distinguishes between technologies that could face export prohibitions and those requiring government approval or licensing.
An important distinction is that the proposal targets manufacturing technology transfers and associated equipment. It does not amount to a blanket prohibition on exports of finished solar panels.
China also introduced an interim pre-export registration requirement for specified technology transfers from October 16.
The public consultation period is scheduled to close on November 15, 2026. The final scope and implementation of the proposed restrictions will determine how significantly Indian manufacturers are affected.
German Companies Centrotherm and RENA Technologies Attract Interest
Indian solar manufacturers are already engaging with European technology suppliers to explore alternatives to Chinese manufacturing equipment.
Saatvik Green Energy is among the companies evaluating European suppliers, including Germany-based Centrotherm and RENA Technologies, for advanced solar cell manufacturing capabilities.
These companies operate in specialised areas of semiconductor and solar manufacturing equipment, making them potential partners for Indian manufacturers looking to develop more sophisticated production facilities.
Avaada Group is also exploring opportunities with European equipment manufacturers, engineering specialists and research institutions.
The interest is not limited to Germany. Manufacturers are also considering technology partnerships in Japan, South Korea, Italy and Australia.
However, industry representatives have cautioned that replacing Chinese equipment will not be straightforward. Some international suppliers also depend on Chinese manufacturing networks for components, meaning diversification may not eliminate all supply-chain risks.
European Solar Equipment Could Cost 40%–50% More
One of the biggest challenges for Indian manufacturers is the higher cost of European manufacturing equipment.
According to industry estimates reported by Mint, sourcing equipment from European suppliers could increase costs by approximately 40%–50% compared with Chinese alternatives.
This could affect the financial viability of new manufacturing projects, particularly companies planning large-scale production facilities.
Chinese suppliers have built substantial manufacturing capacity and established supply chains, allowing them to offer equipment at competitive prices and provide technical support at scale.
European manufacturers may offer advanced engineering capabilities, but their available production capacity could be insufficient to meet the demand emerging from India’s solar manufacturing sector.
Vinay Rustagi, chief business officer at Premier Energies, cautioned that it remains uncertain whether suppliers outside China can meet the scale of India’s equipment requirements.
The financial impact also extends beyond the initial purchase price. Longer equipment delivery schedules, installation requirements, production ramp-up periods and maintenance arrangements could increase project costs.
Manufacturers must therefore evaluate equipment based on its lifetime production efficiency rather than simply comparing upfront prices.
India’s Solar Manufacturing Supply Chain Faces a Major Gap
India has made significant progress in expanding solar module manufacturing, but its upstream production capabilities remain relatively limited.
The solar manufacturing process involves several stages:
- Polysilicon: High-purity silicon is produced from raw materials.
- Ingots: Polysilicon is melted and formed into large silicon crystals.
- Wafers: Ingots are sliced into thin silicon sheets.
- Solar cells: Wafers are processed to convert sunlight into electricity.
- Solar modules: Multiple cells are assembled into finished panels.

According to figures cited by The Indian Express, India has approximately 233 GW of annual solar module manufacturing capacity, while solar cell capacity is estimated at around 30 GW. Installed ingot and wafer capacity is approximately 2 GW.
This imbalance means that manufacturers can assemble substantial quantities of solar modules but still depend heavily on imported upstream components and technology.
India’s ambition is to develop approximately 100 GW of domestic capacity across wafers, ingots and polysilicon by the end of this decade. Around 30 GW of wafer and ingot capacity is currently in the pipeline, according to industry estimates reported by Mint.
China’s proposed restrictions could complicate this expansion if manufacturers face delays in obtaining equipment, technical support and production technology.
Indian Solar Manufacturers Face Higher Costs and Project Delays
The immediate impact of China’s proposed restrictions will depend on individual companies’ procurement arrangements.
Manufacturers that have already received their equipment may face less disruption than companies still negotiating purchases or waiting for shipments.
The uncertainty could affect:
- New wafer and ingot manufacturing projects
- Advanced solar cell production facilities
- Equipment delivery schedules
- Access to technical support and spare parts
- Project commissioning and production targets
- Manufacturing costs and profitability
The challenge is particularly significant for companies planning advanced TOPCon and other high-efficiency solar cell production lines.
Even when alternative equipment is available, manufacturers must ensure that production facilities achieve the required output, quality and efficiency levels.
Industry executives have also highlighted the importance of production yields and polysilicon availability. A manufacturing line that takes longer to reach its designed production efficiency could create additional financial pressure.
India Also Needs to Build Domestic Solar Equipment Capabilities
Diversifying imports is only one part of India’s response. The longer-term objective is to develop domestic manufacturing capabilities for the machinery and technology required across the solar supply chain.
Industry representatives estimate that building competitive domestic equipment manufacturing capabilities could take at least three years under favourable conditions and as long as five years more realistically.
Developing this ecosystem will require investment in research and development, precision engineering, skilled workers, manufacturing infrastructure and partnerships with international technology providers.
India’s solar manufacturing industry will also need reliable access to specialised components, maintenance services and technical expertise.
The opportunity extends beyond solar equipment. Reducing dependence on imported manufacturing machinery could strengthen India’s position in other clean-energy industries, including battery production.
The Bigger Picture
India’s search for German solar technology highlights a structural weakness in its renewable-energy manufacturing ambitions. The country has developed substantial module production capacity, but the upstream stages that produce polysilicon, ingots and wafers remain heavily dependent on imported technology and equipment.
China’s proposed export restrictions have accelerated the need for alternative suppliers. Germany and other European countries could help India diversify its technology partnerships, but higher equipment costs and limited supplier capacity may slow the transition. Ultimately, the challenge is not simply to replace Chinese machinery but to build a competitive domestic manufacturing ecosystem.
Looking Ahead
The November 15 consultation deadline will be an important milestone in determining the future scope of China’s proposed solar technology export controls. Indian manufacturers will be watching whether technologies such as TOPCon, HJT and back-contact manufacturing remain subject to licensing requirements and how the rules affect existing procurement agreements.
For India, the next phase will involve securing alternative equipment suppliers, strengthening domestic engineering capabilities and ensuring that new solar manufacturing projects remain commercially viable. The ability to develop reliable upstream production could determine whether India becomes a more self-reliant solar manufacturing hub or continues to depend on imported technology despite expanding its domestic production capacity.
