Kosol Energie, an Indian solar module Manufacturer, has signed a Memorandum of Understanding (MoU) with Valeo for supplying 600 tons of solar PV ribbons and busbars from November 2025 to October 2026. This agreement was made during the Renewable Energy India (REI) Expo 2025 in Greater Noida. At the event, Kosol Energie also launched its new 720 Wp solar modules, aimed at optimizing space in large-scale solar projects. The company, with a manufacturing capacity of 3.3 GW, also engages in EPC work for multiple solar installations and plans to expand into solar tracker and solar structure manufacturing The recent memorandum of understanding (MoU) signed between Indian.
Module maker Kosol Energie and component supplier Valeo Products marks a strategic milestone for India’s domestic solar manufacturing landscape. Under the terms of the deal, Valeo will supply approximately 600 tons of PV ribbons and busbars to Kosol, with the supply window spanning November 2025 through October 2026 Kosol Energie, headquartered in India, has been active in solar module manufacturing and in the EPC segment. According to published reports, the company currently operates a module manufacturing capacity of 3.3 GW and has recently launched a 720 Wp module variant aimed at utility-scale installations, signifying its intention to compete at higher watt-levels.
Why This MoU Matters
The other hand, Valeo Products is a specialist in PV interconnects ribbons and busbars being integral elements of the cell-to-module chain. They bring in experience and are positioned to serve module makers looking to build scale in India In the module manufacturing value chain, components like ribbons and busbars though relatively small in cost compared to cells or wafers play a disproportionate role in quality, reliability, and production throughput. By securing a supply of 600 tons, Kosol is effectively locking in a supply of these critical inputs for a full year, which helps in production planning, cost control, and quality assurance. The timeline spans a full 12 months which suggests Kosol.
Expects steady production volumes and possibly ramp-up phases Beyond the immediate operational aspect, this partnership signals something larger: a strengthening of the supply chain within India. As the Indian solar module manufacturing sector expands, securing domestic suppliers for components reduces reliance on imports, which is both a risk mitigation strategy and aligns with national manufacturing ambitions. According to recent data, India’s module manufacturing capacity is rising sharply from 72 GW in March 2024 to nearly 118 GW by July 2025.
Strategic Implications for Kosol Energie
For Kosol, this MoU helps in multiple respects. First, it ensures continuity of supply for two of the key materials needed in module assembly. This is particularly timely because the company has just unveiled a new 720 Wp module. Having secured the input materials helps Kosol avoid bottlenecks, especially as module sizes grow higher and production tolerances tighten. Second, this (Busbar) move helps Kosol project a level of reliability and supply chain maturity that may bolster its credibility with large-scale EPC clients or utility customers. Third, because the MoU covers a defined period (Nov 2025–Oct 2026), it gives Kosol the window to ramp up manufacturing, plan inventory, and perhaps negotiate favourable pricing or volume terms.
From Valero’s perspective, this MoU gains them a significant customer commitment 600 tons is not trivial in this space. It indicates that Valeo is confident of meeting the quality, volume and timing demands of a module manufacturer. The agreement could also be a signal to the market that component suppliers are aligning themselves with fast-growing module makers in India. In a market where component supply can be strained (due to global demand, trade restrictions, logistics issues etc.), a committed partnership helps both parties.
Broader Industry Context
This deal sits within a broader wave of manufacturing growth in India’s solar sector. Government policies, domestic demand, and export opportunities are pushing Indian manufacturing to scale up rapidly. As module and cell capacities expand, critical components like ribbons and busbars become more than just commodities they become enablers of scale, quality, and competitiveness. The fact that a domestic maker (Kosol) is tying up a domestic component supplier (Valeo) is a clear indicator of supply-chain localisation in action. It’s also an encouraging sign for jobs, manufacturing infrastructure, and technological maturity within India.
While the MoU is positive, there are of course caveats. Supply of 600 tons sounds robust, but if Kosol scales faster than expected, or if module specifications change higher watt modules needing different ribbon/busbar designs), the agreement may need to be renegotiated or supplemented. Quality control is critical if the ribbons or busbars fail or under-perform, it could affect module durability, warranty claims, or yield in the field. For Valeo, meeting the supply schedule, maintaining consistent quality, and managing cost pressures (raw materials, logistics, exchange rates) will be key. And for the broader industry, localisation of supply is still a work in progress components further upstream.
In the near-term, one will watch whether Kosol’s production ramps as planned and whether the supplied components meet performance and reliability benchmarks. In the medium term, if this collaboration succeeds, it may encourage more module makers in India to forge such module MoUs with domestic component suppliers potentially accelerating India’s localisation agenda. Also, as module manufacturers move to higher watt-counts and larger formats, ribbon and busbar technologies may evolve To understand where this deal fits into module demand and manufacturing growth.
Q1. What exactly is the MoU between Kosol Energie and Valeo Products?
The agreement covers the supply of 600 tons of PV ribbons and busbars from Valeo to Kosol between November 2025 and October 2026.
Q2. Why are PV ribbons and busbars important in solar module manufacturing?
PV ribbons and busbars serve as key interconnects and current-carrying components in solar cells and modules, enabling efficient power flow and module reliability.
Q3. What is the context of this collaboration for Kosol Energie?
Kosol Energie is scaling its solar module manufacturing; this supply agreement secures material for its upcoming production runs and supports its expansion into module manufacturing and possibly structures/trackers.
Q4. Who is Valeo Products and what do they bring to the table?
Valeo Products is an Indian manufacturer specializing in interconnects and busbars for PV modules. It has a track-record in supplying to the solar manufacturing ecosystem in India.
Q5. What does this mean for the Indian solar industry overall?
This kind of deal underlines the maturation of India’s solar manufacturing supply chain. By securing domestic supply of critical components, manufacturers like Kosol reduce import dependence and enhance self-sufficiency.
