Solar energy is no longer a niche investment in India. It is emerging as the mainstay of the national power matrix. But most new entrepreneurs are after the panels and don’t think about the hardware which supports the panels. That’s where the manufacturing opportunity is. Today, one of the underutilized but promising business concepts in the renewable energy value chain is the solar mounting structure and panel frame extrusion made of aluminium.
This article outlines the reasons why it is becoming popular, the type of support available from governments, and some specific concepts and business models developed around this one product. It’s written from the perspective of founders looking for a practical starting point in the Indian context and not textbook theory.
Why Aluminium Solar Mounting Structures Are In Demand
No solar installations, rooftop or otherwise, are possible without a frame. That frame needs to be resistant to corrosion, be able to support the structure, and be able to last 20 years. In most uses, aluminium is a better fit for this short than steel since it is not prone to rust, is lighter and extrudes into accurate cross-sections.
The solar power installed in India has increased rapidly. According to Invest India, a data brokerage that monitors investment environment in the solar renewable energy sector, the installed solar power capacity has increased from 2.82 GW in 2014 to more than 123 GW by August 2025. That’s more than a 40-fold jump in a little more than 10 years. For each gigawatt of solar power, there are thousands of tonnes of extruded aluminium in the form of framing and mounting components.
However, the market is also solid on the manufacturing side. In this context, the aluminium extrusion industry in India is growing at a CAGR of 12.1% to cross the US$ 2.60 billion mark in 2025 and is anticipated to reach a market size of US$ 9.77 billion by 2035, owing to solar infrastructure requirement and the lightweighting of EVs in construction, among other factors. Solar mounting structures and panel frames are not on the edges but in the middle of this growth curve.

Structural Demand, Not Just Cyclical Demand
It’s not just a single construction spree. Each year, solar installations are continuing, as India strives to reach the 2030 renewable energy capacity goal. DPIIT data cited by IBEF puts the figure for non-conventional energy sector as more than Rs. Total cumulative FDI inflows of 2,04,341 crore from April 2000 to June 2025. No other product is available for the new capacity additions.
The global aluminum extrusion market is also undergoing a transformation of its players’ strategies. Companies are increasingly looking to add value to the product, such as machining, anodising, powder coating, and assembly, rather than just extruding the product. That’s an invitation for an Indian entrepreneur. Completion of mounting structures that are ready for use requires a better margin than raw extruded sections sold by the foot.
Government Policies and Incentives Supporting This Sector
In most other manufacturing lines, policy support is not as direct as it is here. This business is directly or indirectly touched by several schemes as it fits into the solar ecosystem.
Production Linked Incentive (PLI) for Solar PV
The Ministry of New and Renewable Energy runs the PLI Scheme for the National Programme on High Efficiency Solar PV Modules. While the PLI itself targets cell and module makers, its ripple effect matters: the scheme has provisions for a five-year incentive post commissioning on the manufacture and sale of high-efficiency solar PV modules, with an outlay running into thousands of crores across two tranches. Every new integrated module plant needs a local, reliable supplier of mounting frames and structures — and few module makers want to also run an extrusion line.
Approved List of Models and Manufacturers (ALMM)
This policy is also a measure of protection for your customer base in a roundabout way. The basic Customs Duty (25% for imported cells and 40% for imported modules) and the requirement to list all ALMMs were introduced in 2022, as per the Council on Energy, Environment and Water. This ensures that the manufacturing of the modules will remain within the country instead of coming through the Chinese imports and thus will help in maintaining the demand for mounting structure within the country.
MSME and Udyam Registration benefits
It is important for any small or medium business who want to be in this business to register their own on the Udyam portal. The Credit Guarantee Scheme, priority sector lending and delayed payment protection as per MSMED are all available for registration which are relevant to a capital-intensive extrusion business.
Invest India and Make in India Support
Both platforms actively promote renewable energy component manufacturing. Invest India’s renewable energy sector page notes that 100% FDI is permitted under the automatic route for renewable energy generation and distribution projects, with the sector drawing US$ 23 billion in foreign investment between April 2020 and June 2025. The Make in India renewable energy portal similarly positions component manufacturing, including structural hardware, as a strategic priority as the country works toward a higher non-fossil fuel power capacity share.

Multiple Business Ideas For Startups in Aluminium Solar Mounting Structure and Panel Frame Extrusion
Small-Scale Aluminium Solar Mounting Structure Manufacturing Unit
For first time entrepreneurs, a small-scale unit that concentrates specifically on Aluminium Solar mounting structures is suitable. The main process is to buy aluminium billets or buy pre-extruded aluminium profiles, cut, punch and anodise or powder coat and then assemble them into rooftop or ground-mount racking systems. This does not demand the purchase of an extrusion press from the start; many small presses begin as press fabrication and finishing plants which then purchase raw extruded sections from larger mills and add value by virtue of precision cutting and surface treatments. The local rooftop solar installers, EPC contractors and household solar vendors are already customers. Demand for rooftop solar under schemes such as PM Surya Ghar is spread across geographies, not in a few, large buyers, making it suitable for smaller operation, without being overly dependent on a buyer.

Contract Manufacturing or Toll Manufacturing Model
In this model, the entrepreneur does not deal with end users at all. Instead, the unit manufactures mounting structures and panel frames for solar module companies and/or EPCs, who provide the design requirements and/or raw materials and claim finished products. This is ideal for entrepreneurs looking for reduced marketing expenses and consistent sales. In the aluminium extrusion business in general, and in the case of solar hardware in particular, toll manufacturing agreements are in use. The relationship is viable because big module makers would prefer to invest capital in cell and module lines, rather than a parallel extrusion and fabrication plant. A toll manufacturer becomes an extended arm of the two or three anchor clients, thus cutting the sales cycle significantly when compared to open-market selling.
Private Label and White-Label Supply Model
Some businessmen decide to produce the typical design of mounting structures and have it sold under private label by solar distributors, EPC companies, or even end-users who sell solar accessories through online retailers. This model relies on a few standard designs, engineered to code, and customizable to rooftop conditions; fixed-tilt rooftop mounts, ballasted ground mounts and elevated structures for uneven ground to be rebranded and packaged under a buyer’s name. Since the engineering is seldom different between brands, a manufacturer using this model enjoys long production runs and predictable tooling costs. It also provides an avenue for supplying smaller regional solar installers who don’t have the scale to create structural designs or test them, which ensures the manufacturer a broad and shallow but secure customer base.
B2B Bulk Supply to Institutions and Industry
The mounting structures for large-scale installation on a rooftop—for instance in the large industrial setting, or on government buildings or railway stations—often need to be centrally tendered. A manufacturer geared for this model prioritises fulfilling technical requirements, wind-load certifications and delivery requirements required by big institutional tenders in lieu of customisation for retail businesses. This means it will need to invest more capital in working capital and compliance records at the outset, but will pay off for manufacturers that have long production runs and single really big orders. Since public procurement is increasingly favouring domestic manufacturers as per Make in India policy, a compliant Indian manufacturer who is a bidder for institutional and government tenders has a structural edge over the importers, especially in large public solar programmes at the State and Central level.
Export-Focused Aluminium Solar Mounting Structure Production Unit
As the country becomes a key player in aluminium extrusion and enjoys relatively low manufacturing costs, it is likely to increase its share in producing mounting structures for export, especially to countries in the African continent, South East Asia and Middle East which are witnessing a growing acceptance of solar energy. An export unit will generally need greater structural and corrosion resistance that meets international standards and complies with the requirements of its target countries. It will also need more detailed quality documentation than a domestic unit. This model is suitable for shipment to regionals, not direct-to-installer exports, due to the cost of freight and the logistics of shipping larger structural pieces. The path of entrepreneurs who choose this route typically follows the domestic supply first, then a solid quality track record and, eventually, into export contracts.

Import–Export Opportunity Analysis
The aluminium extrusions industry has been primarily dependent on domestic demand and export orders, and the solar related business is an additional business wing in the trade. On the import front, the risk of being dependent lies in raw aluminium and some alloy grades, but not with finished mounting structures, which, with its existing extrusion base, India is well poised to produce as well.
Opportunity is growing on the export side, as many emerging solar markets are getting on-board faster than they are able to establish local component manufacturing. A domestic manufacturer with good quality control and cost efficiency can provide finished mounting structures to EPC contractors in the overseas solar projects. The Export Import Data Bank, a government resource, provides trade data that helps entrepreneurs monitor past shipment trends and identify key markets before adopting an export-first approach.
The domestic pull is stronger for the short term in the meantime. With India’s ALMM list growing from 2.3 GW module capacity in 2014 to 100 GW by August 2025, with over 100 manufacturers listed with 123 facilities, each facility will require a consistent supply chain of mounting structure to feed the downstream installations. It’s usually better for most new entrants to develop a solid domestic order book first and then look for exports.
Indian MSME Success Stories in Aluminium and Solar Component Manufacturing
Hindalco Industries focuses on the extrusion segment as its core business. Over the years, the company has expanded from primary aluminium production into value-added products such as structural extrusions. These products serve the construction, transport, and renewable energy sectors. The company gained a scale advantage by vertically integrating raw material supply with extrusion operations. Smaller entrants can adopt a similar approach on a proportionate scale by securing stable billet supply contracts instead of relying on spot purchases.
Jindal Aluminium also expanded its business with regular investments in extrusion press capacity and finishing processes like anodising and powder coating, thus catering to customers in the renewable energy, architectural and industrial segments from the same manufacturing facility. Whereas, in the case of MSMEs, the decision logic is worth noting here because rather than limiting production to the building sector, Jindal developed the production lines that could switch from building extrusions to industrial applications such as solar hardware as the demand changed.
Emmvee Group, though primarily known as a solar module manufacturer, offers a relevant lesson for component-focused MSMEs too. The company’s decision to invest heavily in integrated manufacturing, including allied component production, reflects a broader industry pattern: Emmvee announced a Rs. 15,000 crore investment to establish a manufacturing facility generating around 10,000 jobs, signalling how seriously large players are backing India’s solar manufacturing ecosystem. For a smaller mounting structure manufacturer, aligning early with such expanding module producers as a supply partner can be a faster growth route than building a standalone brand from scratch.

Conclusion
Aluminium solar mounting structure and panel frame extrusion sits at an intersection few new entrepreneurs think to explore directly. Everyone talks about solar panels and modules; fewer talk about what physically holds them up, year after year, through monsoons and heatwaves alike. That gap is precisely where the opportunity lives.
Whether you approach this as a small fabrication unit, a contract manufacturing partner to larger module makers, a private-label supplier, an institutional bulk vendor, or an export-focused producer, the underlying demand driver stays the same: India’s solar capacity keeps expanding, and every new installation needs mounting hardware. For founders serious about entering industrial manufacturing with strong policy support, this business ideas category deserves careful evaluation. Start with a rigorous feasibility assessment before ordering any machinery.
