STM 26

STM-26 is a 184 mm × 184 mm Solar Thermal Module designed as the fundamental unit for rooftop solar panels. It represents the first product in a new class of sustainable renewable energy systems under development at UmaHari.

STM-26 modules create a modular energy platform that captures solar thermal energy — including infrared radiation — and converts it into usable electrical power through a proprietary energy conversion architecture.

The STM-26 module is envisioned to be manufactured using advanced bio-based polymers wherever technically feasible. By replacing conventional petroleum-derived plastics with durable bio-plastics, the module aims to further reduce its embodied carbon footprint while supporting a more circular manufacturing ecosystem.

06 Philosophy

A Manufacturing Philosophy Built for the Developing World

Imported PV Manufacturing

Characteristics: Increasingly intricate, exclusive, and highly capital-intensive.

Result: Consolidates wealth and technological control in a single geographic monopoly (China). Locks out emerging Indian competitors who cannot match the economy of scale.

Indigenous Thermal Manufacturing

Characteristics: Utilises standard manufacturing processes and simpler tooling.

Result: 'Monopoly-Free'. Democratises production, enabling a distributed manufacturing and repair ecosystem across multiple Indian states, driving massive local employment.

For over half a century, the world has pursued one dominant pathway for solar energy— photovoltaics. While this approach has transformed renewable energy, it has also concentrated manufacturing within a limited global supply chain.

STM-26 has been conceived with a fundamentally different manufacturing philosophy.

The module is designed around engineering materials that are widely available across global manufacturing ecosystems. The overall grammage of metals, non-metals, Bio-polymers and electronic components required for each module indicates a credible pathway toward manufacturing costs that are intended to be comparable with today's photovoltaic panels while offering significant opportunities for further cost reduction through optimization, automation and production scale.

Unlike technologies dependent on highly specialized semiconductor manufacturing, STM-26 has been conceived to enable manufacturing using industrial capabilities that already exist in many developing economies

This creates the opportunity for countries to participate not only as consumers of renewable energy, but also as manufacturers of renewable energy technology.

07 Renewable

Beyond Renewable Electricity

STM-26 is designed to utilize solar thermal energy, including infrared radiation, creating opportunities beyond electricity generation alone.

By harvesting thermal energy that would otherwise contribute to rooftop heating, widespread deployment of STM modules has the potential to reduce thermal loading on buildings. Subject to future validation, this approach could contribute toward mitigating aspects of the Urban Heat Island effect while simultaneously generating clean electricity.

This creates a compelling dual-value proposition:

Renewable electricity generation.

Potential contribution to cooler buildings and more climate-resilient cities.

Such a proposition aligns naturally with future smart-city initiatives, sustainable construction practices and climate adaptation strategies.

08 Circular Economy

A Toxic Time Bomb Versus
a Purpose-Built Circular Economy

STM-26 has been conceived from the outset as a product for the circular economy.

Unlike many existing renewable energy products, the plaƞorm is designed with repairability, modular replacement and recyclability as core engineering principles rather than end-of-life considerations.

Use of Bioplastics in STM complements the core philosophy of the STM plaƞorm— renewable energy generated by renewable materials. Combined with its repairable and recyclable architecture, bio-based construction has the potential to create one of the most environmentally responsible renewable energy plaƞorms, reducing dependence on fossilderived materials and enabling a cleaner, more sustainable manufacturing value chain.

09 Indigenous Thermal

The Strategic Diagnostic: Imported PV vs. Indigenous Thermal

STM-26 is not simply another renewable energy product.

It is the first building block of a new modular energy platform.

As future generations improve efficiency, manufacturing methods and energy conversion technologies, they can be integrated into the same STM architecture without changing the fundamental product ecosystem.

The long-term opportunity extends beyond selling modules.

It is about establishing a globally scalable platform that enables nations to manufacture their own renewable energy hardware, diversify global supply chains, strengthen energy security and accelerate the transition toward cleaner and more resilient energy systems.

Our ambition is not merely to compete with photovoltaic panels.

Our ambition is to establish the Solar Thermal Module (STM) as a new global standard for modular sustainable renewable energy—one that is affordable, repairable, recyclable, locally manufacturable and designed to empower the next generation of energy independence.
