Description
If you're building a system that needs to perform in the real world not just on paper the Heliene 72M G1 Bifacial 390W delivers bankable Tier 1 quality with bifacial technology that keeps harvesting energy long after the sun shifts position. This pallet of 26 panels gives you 10,140W of total array capacity straight off the truck.
- Bifacial Energy Harvest – Captures additional energy from the rear side of the panel with a 70% bifaciality factor, boosting real-world output beyond the rated 390W per panel.
- 20.4% High-Efficiency PERC Cells – Built with the latest 72-cell Monocrystalline PERC technology for maximum power density in a proven form factor.
- Anti-Reflective Solar Glass – 3.2mm low-iron, high-transmission glass with anti-reflective coating delivers more energy output across all light conditions throughout the day.
- Rugged Double-Webbed Frame – 15-micron anodized aluminum alloy frame withstands wind, snow, and mechanical stress loads up to 113 psf on the front and 50 psf on the back.
- 25-Year Linear Performance Guarantee – Backed by a 15-year workmanship warranty and a 25-year linear power guarantee with performance down to 86% at end of life.
Designed and manufactured to ISO 9001 standards with fully automated robotics and computer-aided inspection, every Heliene panel that leaves the factory is built to the same exacting spec. It has earned Top Performer rankings from PV Evolution Labs and carries UL61215 and UL61730 certifications for peace of mind on every install.
The bifacial glass-backsheet construction and proven PID resistance make this module equally at home in high-temperature, high-humidity environments where lesser panels start to degrade. Whether ground-mounted on an open field or installed on a high-visibility rooftop, the framed glass-backsheet aesthetic keeps the install looking sharp.
With a 1500V system voltage rating and Stäubli MC4 connectors standard, this pallet of 26 integrates cleanly into both residential and commercial system designs without extra adapters or compatibility concerns.
