Heliene and Caelux announced their Hybrid-Tandem solar module is in commercial-scale production for the U.S. market, achieving module conversion efficiencies up to 27%+. The companies entered a multi-year, multi-gigawatt agreement to commercialize the module.

Why it matters

The module integrates Caelux's Energy Producing Glass into Heliene's existing manufacturing lines without an entirely new production setup. Its capability to generate up to 20% more energy than a conventional N-type module could affect how much power U.S. solar installations produce.

The module achieves conversion efficiencies up to 27%+ and is designed to produce up to 20% more energy than a conventional N-type module. Heliene's two U.S. facilities have a combined annual capacity of 1.3GW, and the 29% efficiency target for 2028 remains a projection.

The players

Heliene

Heliene is a solar module manufacturer that operates two U.S.-based facilities and employs more than 500 full-time solar industry professionals.

Caelux

Caelux is a Baldwin Park, California-based company that develops Energy Producing Glass technology.

The details

Caelux's Energy Producing Glass forms the top layer, which is combined with compatible silicon N-type cells on Heliene's manufacturing lines in Mountain Iron, Minnesota. An initial industrial-scale commercial order is underway, and the module will be displayed at Heliene's booth at RE+ in Las Vegas.

Timeline

  1. November 10, 2026: Companies announce the Hybrid-Tandem module is in commercial-scale production.

  2. November 17-19, 2026: The module is displayed at the RE+ trade show in Las Vegas.

  3. 2027: Modules become available for deliveries.

  4. 2028: Target for module efficiencies to exceed 29%.

The Tech Race

The Hybrid-Tandem module is positioned against conventional N-type silicon modules, which the companies say it outperforms by up to 20% in energy output. Its path to a 29% efficiency target by 2028 would extend a steady push in U.S. solar manufacturing to raise module efficiency.

Installers and developers weighing module options for 2027 deliveries can compare the claimed 20% energy gain against conventional N-type modules. Buyers should confirm how the 27%+ efficiency figure and future 29% target translate into project output before committing.

The takeaway

Higher module efficiency can increase energy output without requiring entirely new production lines, which may matter as U.S. solar buyers evaluate next-generation products. Watch whether the companies reach their 29% efficiency target by 2028.

What happens next

Modules will be displayed at RE+ in Las Vegas from November 17-19, 2026, and deliveries are scheduled for 2027.
