RICH SOLAR MEGA 590 Bifacial Solar Panel
590 watts from the front, bonus power from the back. The MEGA 590 Bifacial turns reflected light into real production.
The MEGA 590 Bifacial uses 144 16-busbar N-Type TOPCon cells with up to 25.1% cell efficiency to deliver 590W from the front face alone. Its dual 2.0 mm tempered glass construction lets the rear side capture reflected light for up to 25% additional power gain, depending on surface albedo. With a 1500 VDC max system voltage, IP68 junction box and 5400 Pa snow load rating, it is built for ground mounts, carports and large-scale arrays. Every panel carries UL 61730 certification, a 25-year output warranty and a 10-year workmanship warranty.
Why it stands out
More Harvest From Every Square Foot
Bifacial N-Type TOPCon technology captures direct sunlight on the front and reflected light on the back, making the MEGA 590 an ideal choice for elevated ground mounts, light-colored surfaces and commercial-scale arrays.
Best for: Homeowners, farms, businesses and installers building ground-mount, carport or commercial arrays who want maximum output per panel plus bifacial rear-side gain.
