24V Bifacial Solar Panel · N-Type TOPCon · 550W
550W Bifacial Solar Power for Residential, Commercial & Agricultural Installs
The MEGA 550 captures light from both the front and rear of the panel — up to 25% additional power from bifacial gain, depending on surface albedo — built for larger-scale grid-tie or off-grid installations and sold in bulk pallet quantities.
What Sets the MEGA 550 Apart
Bifacial Design
- Captures light on both front and rear faces of the panel
- Up to 25% additional power gain from the rear side, depending on surface albedo
- 2.0mm front and rear tempered glass supports light capture from both sides
Cell Technology
- 16-busbar N-Type TOPCon cells, up to 25.1% efficiency
- 144-cell configuration delivers a reliable 550W output
- Power tolerance of 0 to +5W — never undershoots the rated output
- Strong low-light performance on cloudy days and at dawn or dusk
Certified & Versatile
- PID-resistant and 100% EL-inspected against microcracks
- Rated for 5,400 Pa snow loads and 2,400 Pa wind loads
- Certified to UL 61730, IEC 61215, and CSA C22.2 standards
- Compatible with both grid-tie and off-grid inverters
Installation & Built-In Components

Common Questions
What does “bifacial” mean for this panel?
The panel has tempered glass on both the front and rear, allowing it to capture sunlight reflected off the ground or roof surface beneath it — adding up to 25% more power depending on how reflective that surface is.
Can this panel be used in a grid-tie system?
Yes — the MEGA 550 is compatible with both grid-tie and off-grid inverters, suiting utility-connected residential and commercial installations as well as fully off-grid setups.
What quantities does this come in?
It’s sold in pallets of 8, 10, or 12 panels. For other quantities, Rich Solar’s sales team can be reached directly by phone or email.
How much does mounting orientation affect bifacial gain?
Actual rear-side gain depends on the reflectivity (albedo) of the surface beneath the panel — lighter, more reflective surfaces like white gravel or light-colored roofing generally produce a greater bifacial gain than dark surfaces.
Do I need a licensed installer for a system this size?
Given the scale and voltage involved in residential, commercial, or agricultural installations — especially grid-tie systems — installation should be handled by a qualified, licensed electrician or solar installer familiar with your local code.
