Spinkraft

What Spinkraft does

Spinkraft, legally Aerem Solutions Private Limited and operating primarily through its SunStore brand, is a B2B solar equipment procurement marketplace headquartered in Mumbai, Maharashtra, India. The platform aggregates modules (HJT, Mono PERC, Thin Film), inverters (grid-tied, hybrid, off-grid), batteries, cables, solar balance-of-system components (DCDB, ACDB, installation accessories), structures, and pre-configured solar kits from more than 20 partner brands including Waaree, Jinko, Trina, Luminous, Havells, Polycab, Vikram Solar, Goldi Solar, and Axitec. Customers — primarily EPC companies and solar installers — browse the catalog, add items to a cart, and submit quote requests; SunStore confirms availability and returns quotes within 24 hours, after which customers confirm and pay before choosing between last-mile delivery and warehouse pickup.

The underlying technology is a procurement platform with an integrated quote-to-order workflow, partner management portal (Partner Portal), and an embedded financing interface via Net Zero Finance that offers credit lines up to ₹3 Cr. The platform is part of a broader Aerem ecosystem that includes AeRoc Monitoring for solar asset performance tracking, suggesting an intent to extend beyond pure transactional procurement into post-installation operations. The technology stack is described as standard e-commerce and order management rather than AI-native.

The business model is primarily transaction-based hardware sales, with revenue captured on each confirmed order of solar products and BOS components. Pricing is quote-based and not publicly disclosed; final quotes are confirmed before order commitment, and an additional revenue stream is implied through the embedded financing arrangement with Net Zero Finance (likely referral or facilitation economics). The go-to-market motion combines inside sales with a channel-partner model, supported by a B2B partner portal and industry referrals; marketing is supplemented by an organic social presence on Facebook, Instagram, YouTube, and LinkedIn. Customer concentration evidence shows a mix of SMB and mid-market EPCs across India.

Expansion highlights4 records

Broad incumbents

• CleanMax Solar: India-focused C&I solar EPC and rooftop developer procuring modules, inverters and BOS at scale, with embedded financing capabilities. Comparable as both a potential large SunStore customer and as a broader incumbent with in-house solar supply operations.
• Tata Power Solar Systems: Subsidiary of Tata Power offering solar EPC, modules and rooftop solutions across India with its own supply chain and financing partnerships. Comparable as a large-scale competitor in the Indian solar procurement and installation market that EPCs may choose over independent distributors.
• Waaree Energies: India's largest solar module manufacturer with an expanding direct sales and distribution network for EPCs and installers. Comparable both as a key supplier brand on SunStore and as a broader incumbent competing for the same EPC procurement wallet.
• Adani Solar: Large Indian solar module and cell manufacturer with vertically integrated manufacturing and direct sales to EPCs. Comparable as a supplier brand on SunStore and as a dominant incumbent whose D2C channel could disintermediate B2B distributors.

Regional players

• Fourth Partner Energy: India-focused C&I solar EPC and distributed-solar developer with in-house procurement of modules, inverters and BOS. Comparable as a major Indian customer of solar distribution channels like SunStore and as a regional competitor in B2B solar supply.

Direct peers

• Loom Solar: India-based online solar equipment marketplace selling modules, inverters and batteries directly to installers and end customers. Directly comparable to SunStore in product range, online B2B procurement model and India-only distribution focus.
• SolarSquare: India-focused solar installation and equipment provider combining procurement of modules/inverters with installation services and financing for residential customers. Comparable to Spinkraft as a multi-brand solar supply channel in India with embedded finance.
• Freyr Energy: India-based distributed solar installer and equipment supplier that bundles procurement of modules, inverters and BOS with financing and installation services. Comparable as an integrated solar supply-and-installation platform serving SMB and mid-market customers in India.
• SunKing (Greenlight Planet): Distributes affordable solar products and PAYG-financed solar kits across India and emerging markets via a large installer and dealer network. Highly comparable in financing-enabled B2B distribution of solar hardware to last-mile installers.
• EnergySage: US-based B2B solar marketplace where installers source quotes and equipment from multiple manufacturers and financiers. Functionally the closest international analog to SunStore's quote-driven, multi-brand procurement model for solar professionals.
