The numbers from this year's Renewable Energy India Expo (REI), held October 22-24 at the India Expo Center in Greater Noida, tell their own story: more than 54,000 visitors walked the halls over three days, and over 1,000 exhibitors filled the venue — with temporary structures erected in the parking lot to accommodate the overflow. For context, that is nearly double the footfall of REI 2023. India's solar industry has grown from ambition to sheer physical scale, and the expo now mirrors that.
GF New Energy was on the show floor throughout the event, meeting with EPCs, developers, and manufacturer partners from across India's utility-scale and C&I segments. What we observed confirms what the headline data suggests: India is no longer an emerging solar market — it is one of the world's three largest, and it is building domestic manufacturing capacity to match.
But beneath the surface of those impressive numbers, three structural shifts are reshaping the opportunity for tracker component suppliers — and they look different from what the headlines suggest.
Analysts presenting at REI estimate India now has more than 200 GW of annual module assembly capacity, far exceeding the country's expected installation demand of 50-60 GW per year through 2030. This overcapacity is widely expected to trigger a market shakeout beginning in 2027, particularly among manufacturers who operate only module assembly — those without upstream cell production.
For tracker component suppliers, this dynamic has a counterintuitive but important implication. When module makers consolidate, the projects that continue forward tend to be larger, better-financed, and more professionally managed. These are precisely the customers who value component quality, system-level optimization, and long-term O&M planning — not the lowest-bid-everything segment. A shakeout that removes the bottom tier of the market actually improves the average customer profile for quality component suppliers.
Furthermore, the installed base of solar plants continues to grow regardless of which manufacturers survive. India's cumulative installed PV capacity is projected to exceed 100 GW by the end of 2026 and reach 280-300 GW by 2030 (per MNRE targets). Each gigawatt of installed tracking capacity represents a multi-year demand for replacement components — controllers that need firmware updates, bearings that wear, dampers that require inspection. The aftermarket for tracker components is a growing market that is entirely independent of which module manufacturer wins the shakeout.
India's domestic content requirements (DCR) have been steadily climbing up the supply chain. The policy, extended to solar cells in 2026, will further extend to wafers by 2028. The intent is clear: build the entire PV supply chain domestically. Multiple Indian manufacturers — Saatvik, Grew, Solex, Navitas, Reliance, and Adani among them — announced wafer production plans at REI that aim to be operational by 2028.
For international companies trying to export finished modules to India, this is a closing window. But the DCR policy is targeted at modules, cells, and wafers — not at the broader ecosystem of tracker system components. solar tracker controllers (TCU), Network control units (NCU), bearings, and dampers are not subject to domestic content requirements. They fall into the same category as inverters, transformers, and mounting hardware: specialized components where India's domestic manufacturing is still maturing.
This means that while the module market is becoming walled off, the accessory and component market is effectively more open than it was three years ago — because the installed base of trackers requiring these components is growing rapidly, and Indian domestic production of controllers, bearings, and dampers has not scaled proportionally. During our conversations at REI, several Indian EPCs and developer partners confirmed that they continue to source tracker controllers and dampers from specialized international suppliers, and expect to do so for the foreseeable future.
The strategic insight for component suppliers is this: the DCR policy is restructuring the supply chain, but it is restructuring it in a way that pushes opportunity upstream and downstream of the module, not toward the module itself.
India's solar market has historically been dominated by utility-scale ground-mount projects, which has favored tracker system suppliers capable of operating at megawatt and gigawatt scale. But conversations at REI 2026 made clear that the market is diversifying:
Commercial & Industrial (C&I) demand is surging, driven by corporations seeking to lock in long-term energy prices and meet decarbonization commitments. Many of these projects are rooftop or carport installations — not traditional tracker territory — but a growing number are ground-mount systems in the 1-10 MW range that do use single-axis tracking.
Residential + storage is emerging as a new segment. With the cost of residential batteries falling, several manufacturers at REI spoke of bundling PV + storage for the residential market in 2027-2028. While residential systems don't use trackers, the broader maturation of India's solar ecosystem creates a more sophisticated buyer base that understands component quality across all segments.
For GF, the C&I ground-mount segment is particularly interesting. These projects — 2-10 MW, often on industrial land or degraded agricultural land — need the same tracking reliability as utility-scale plants but with simpler commissioning and tighter cost constraints. The GF-S-V2 DC-powered tracker controller, with its integrated lithium battery and self-powered operation, is well-suited to these mid-scale projects where grid availability for controller power may be intermittent.
Across three days of meetings, a few themes consistently emerged from Indian EPCs and developers:
"We need controllers that handle all-terrain." India's solar projects span Rajasthan deserts, Gujarat coastlines, Maharashtra rocky terrain, and Tamil Nadu farmland. A controller that performs identically across dust, humidity, salt air, and temperature extremes is not a luxury — it's a procurement requirement. GF's IP65-rated controllers, tested across -40°C to 60°C operating ranges and CE-certified, directly address this demand.
"Communication is the biggest pain point on large sites." Multiple developers mentioned that communication failures between tracker rows and the plant SCADA system are their #1 source of unplanned downtime. GF's dual-communication architecture — LoRa wireless + RS485 between NCU and TCUs, with Ethernet/4G uplink — was a frequent topic of discussion at our booth. The elimination of communication cabling across large sites resonated strongly with Indian project teams facing high cabling costs and cable-failure rates.
"We want one supplier for the whole tracker kit." Indian EPCs expressed strong interest in sourcing the complete tracker accessory package — controller, NCU, bearing, and damper — from a single supplier rather than procuring each component from different vendors. GF's one-stop product portfolio aligns directly with this procurement preference, reducing their vendor management overhead and ensuring component compatibility.
For tracker component suppliers, the Indian opportunity is not in competing with domestic module manufacturers (that battle is already being fought and won by DCR policy). The opportunity is in being the specialized component partner to the EPCs and developers building India's next 200 GW of tracking-capable projects. The controllers that keep those rows tracking, the bearings that carry those rotations, and the dampers that protect those structures during monsoon-season winds — these are the components that India's domestic supply chain is not yet equipped to produce at scale.
GF New Energy will continue to invest in the Indian market — not as a module supplier, but as the tracker component specialist that Indian EPCs have come to know through multiple REI exhibitions. We welcome Indian developers and EPC partners to connect with us for project-specific requirements.
