Runergy 405W Residential Bifacial Solar Panel (HY-DH108P8B)
Pickup available at Shop location
Usually ready in 2 hours
The Runergy 405W Hyperion (HY-DH108P8B) is a Tier-1 bifacial solar panel built on P-type monocrystalline cell technology with a dual-glass construction. At 20.7% module efficiency and a 70% bifaciality factor, it captures reflected light from roof surfaces and ground-mount albedo to deliver meaningful rear-side energy gains — particularly valuable on light-colored or reflective roofing and ground-mount installations with high-albedo ground covers.
The dual-glass frame eliminates the EVA backsheet delamination risk common in framed modules, improving long-term durability in high-humidity and coastal environments. The module is load-tested to withstand extreme wind (2,400 Pa) and snow (5,400 Pa), making it suitable for high-wind zones and heavy snowfall regions without additional structural engineering in most residential racking designs.

Frequently Asked Questions — Runergy 405W Solar Panel
What type of cell does the Runergy 405W use?
The Runergy 405W (HY-DH108P8B) uses P-Type PERC monocrystalline cells in a bifacial configuration. PERC technology improves light absorption and efficiency compared to standard mono cells, while the bifacial design captures reflected light from the rear for additional energy output.
What is a bifacial solar panel?
A bifacial panel generates power from both the front and rear surfaces. The rear side captures sunlight reflected off rooftops, ground, or nearby surfaces. In the right installation — elevated racking, white roofs, or ground mounts — bifacial panels can produce 5–15% more energy than a comparable monofacial module.
What warranty does the Runergy 405W carry?
The Runergy 405W includes a product/workmanship warranty and a linear power output warranty guaranteeing at least 80%+ of rated output over the warranty term. As an authorized Runergy distributor, Solwel supports warranty claims directly. Call us at (346) 432-4228.
Does the Runergy 405W perform well in partial shade?
The Runergy 405W uses half-cut cell technology, which limits power loss when part of the panel is shaded. For rooftops with significant shading, pairing with microinverters provides the best performance by eliminating string shading losses entirely.
Is this panel suitable for residential rooftop installation?
Yes. The Runergy 405W is sized and rated for residential rooftop installation, compatible with standard rail-based and rail-less racking systems. It is UL 61730 certified for safety in U.S. installations.
