The Rich Solar MEGA 720 Bifacial 720 Watt 24V Solar Panel (model RS-M720BF-33) is a large-format dual-glass bifacial panel with 132 N-Type TOPCon cells, up to 25.1% cell efficiency and a 23.18% 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.
Each order is one pallet of 33 panels, for 23,760W of rated front-side power. Each panel measures 93.9 x 51.3 x 1.3 inches and weighs 85.3 pounds. It works with both on-grid and off-grid inverters, is certified to UL 61730, IEC 61215 and CSA C22.2, and carries a 25-year power output warranty and a 25-year workmanship warranty.
Light reflected from the surface below 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 that surface is.
Each panel produces 720W at 41.3V and 17.4A. A power temperature coefficient of -0.29%/°C helps it hold output as it heats up, and the 0 to +5W power tolerance means each panel is rated to deliver at least 720W 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 is built to withstand salt, ammonia, sand, high temperatures and humidity. The operating range is -40°F to 185°F.
Twelve pre-drilled mounting holes fit ground mounts, Z-brackets, poles and tilt systems. 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 and every panel is 100% EL inspected.
Residential arrays. Rich Solar lists the panel for home systems that reduce electricity costs, grid-tie or off-grid.
Ground mounts. Raised racks over a reflective surface give the rear side light to work with.
Agricultural sites. Add a large-format array to farm and ranch buildings.
Commercial buildings. A full pallet of 33 matching panels supports larger arrays.
A one-sided panel only collects light on the front. The MEGA 720 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 720 is rated for 20W more per panel (720W versus 700W), with a 41.3V and 17.4A maximum power point versus 40.5V and 17.3A, and a 23.18% module efficiency versus 22.53%.
Each panel has a 49.4V open circuit voltage and an 18.5A 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 -0.24%/°C). The maximum system voltage is 1500VDC and the maximum series fuse rating is 35A.
Each order is one pallet of 33 panels. At 85.3 pounds and 93.9 x 51.3 inches per panel, plan handling, storage space and racking for large-format modules.
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.
One pallet holds 33 panels, for 23,760W of rated front-side power.
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 720 Bifacial 720 Watt 24V Solar Panel brings N-Type TOPCon cells, dual-glass bifacial construction and 25-year output and workmanship warranties to large home, farm and commercial arrays, 33 panels per pallet. If you'd like help planning strings, inverters or racking, the Outbound Power team is happy to help.
