The Rich Solar MEGA 450 Bifacial 450 Watt 24V Solar Panel is a dual-glass bifacial panel with 108 N-Type TOPCon cells, up to 25.1% cell efficiency and a 23% module efficiency. Its rear side collects reflected light, and Rich Solar rates it for up to 25% additional power from the back, depending on surface albedo. It works with both on-grid and off-grid inverters and is certified to UL 61730, IEC 61215 and CSA C22.2.
This listing offers the MEGA 450 Bifacial as a pallet of 8, 10, 12 or 36 panels, for 3,600W, 4,500W, 5,400W or 16,200W of rated front-side power. Each panel measures 67.8 x 44.6 x 1.2 inches and weighs 52.9 pounds, and Rich Solar backs it with a 25-year power output warranty and a 25-year workmanship warranty.
Light reflected from the ground, gravel, a light roof or snow reaches the back of the cells through the rear glass. Rich Solar rates the rear side for up to 25% additional power gain, depending on how reflective the surface below is.
The 108-cell layout produces 450W at 32.8V and 13.7A. A power temperature coefficient of -0.29%/°C helps the panel hold output as it heats up, and the 0 to +5W power tolerance means each panel is rated to deliver at least 450W at standard test conditions.
Good IAM (incident angle modifier) and low-irradiation performance help the panel keep producing when sunlight strikes at an angle, on cloudy days and in early mornings and late afternoons. Its design also helps energy production under inter-row shading in multi-row arrays.
High-transmission, low-iron semi-tempered glass on the front and rear, 2.0 mm on each side, protects the cells and lets light reach the back. The panel is rated for 5400 Pa front and 2400 Pa rear loads, and it is built to withstand salt, ammonia, sand, high temperatures and humidity. The operating range is -40°F to 185°F.
An IP68-rated junction box with three diodes feeds 4 mm² leads, 47.2 inches each, with IP67-rated MC4 connectors. The cells are PID resistant, every panel is 100% EL inspected, and non-destructive cell cutting helps minimize micro-cracks.
Residential arrays. Rich Solar lists the panel for grid-tie and off-grid home systems.
Ground mounts. Raised ground racks over gravel, light soil or snow give the rear side reflected light to work with.
Agricultural sites. Add a large-format array to farm and ranch buildings.
Commercial buildings. Build larger arrays with matching panels from one pallet.
A one-sided panel only collects light on the front. The MEGA 450 Bifacial can add rear-side gain when it is mounted above a reflective surface.
The two panels have the same size, weight and construction. The MEGA 450 is rated for 10W more per panel (450W versus 440W), with a 32.8V and 13.7A maximum power point versus 32.3V and 13.6A, and a 23% module efficiency versus 22.5%.
Each panel has a 38.1V open circuit voltage and a 15.0A short circuit current. Size series strings so the combined voltage stays within your inverter or charge controller's input range, keeping in mind that open circuit voltage rises in cold weather (temperature coefficient -0.25%/°C). The maximum system voltage is 1500VDC and the maximum series fuse rating is 25A.
Each option is one pallet of 8, 10, 12 or 36 panels. At 52.9 pounds and 67.8 x 44.6 inches per panel, plan handling and racking for large-format modules. The frame has pre-drilled holes for ground mounts, Z-brackets, poles and tilt systems.
Rich Solar rates the rear side for up to 25% additional power gain. The actual gain depends on surface albedo, which is how much light the surface under the panel reflects.
You can choose one pallet of 8, 10, 12 or 36 panels. Each option's model number is listed in the specifications.
Yes. Rich Solar lists the panel as compatible with both on-grid and off-grid inverters, as well as mainstream optimizers and mounting systems.
Rich Solar provides a 25-year power output warranty and a 25-year limited workmanship warranty on each panel.
The Rich Solar MEGA 450 Bifacial 450 Watt 24V Solar Panel combines N-Type TOPCon cells, dual-glass bifacial construction and 25-year output and workmanship warranties in pallet quantities for home, farm and commercial systems. If you'd like help planning strings, inverters or racking, the Outbound Power team is happy to help.
