Rich Solar MEGA 590 Bifacial 590 Watt Solar Panel

The Rich Solar MEGA 590 Bifacial 590 Watt Solar Panel Turns Front and Rear Light Into Power for Large Home, Farm and Commercial Arrays

The Rich Solar MEGA 590 Bifacial 590 Watt Solar Panel is a large-format bifacial panel that delivers 590W from 144 N-Type TOPCon cells with up to 25.1% efficiency. Its rear side collects light reflected from the surface below, and Rich Solar rates the bifacial design for up to 25% additional rear-side power gain, 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 sells the MEGA 590 Bifacial by the pallet, in quantities of 8, 10, 12 or 36 panels, for 4,720W, 5,900W, 7,080W or 21,240W of rated front-side power. Rich Solar ships this panel by pallet only. For other quantities, contact our team.

Rich Solar MEGA 590 Bifacial 590 Watt Solar Panel Features

Up to 25% Rear-Side Gain

The rear glass lets reflected light from gravel, concrete, light-colored ground or snow reach the back of the cells. Rich Solar rates that rear side for up to 25% additional power gain, depending on surface albedo.

16-Busbar N-Type TOPCon Cells

The 144-cell layout uses 16-busbar N-Type TOPCon cells with up to 25.1% efficiency. Excellent IAM and low-light performance help the panel produce at low sun angles, on cloudy days and at dawn and dusk.

At Least the Rated Output

The 0 to +5W power tolerance means each panel delivers at least its rated 590W at standard test conditions.

Dual-Glass Construction

Tempered glass on the front and rear, 2.0 mm on each side, maximizes durability and bifacial performance. The anodized aluminum frame is strong, light for its size and corrosion resistant.

Rated for Snow, Wind and Weather

Each panel is rated for 5,400 Pa snow loads and 2,400 Pa wind loads and operates from -40°F to 185°F. The IP68 junction box and IP67 connectors keep out dust and water, the cells are PID resistant, and every panel is 100% EL inspected to help prevent microcracks.

Ready for Racking

Eight pre-drilled mounting holes fit Z brackets, tilt mounts, pole mounts and ground racking. Pre-attached 12 AWG leads, 4 ft each, with MC4 connectors speed up string wiring.

25-Year Output Warranty

Rich Solar backs every panel with a 25-year output warranty and a 10-year workmanship warranty.

Real-World Applications

Residential arrays. Rich Solar lists the panel for home systems that reduce electricity costs, on-grid or off-grid.

Ground mounts. Mount panels on raised racks above a light surface so the rear side has reflected light to collect.

Agricultural sites. Power barns, pumps and outbuildings with a high-output array.

Commercial buildings. Build large arrays for shops, warehouses and remote facilities.

How It Compares to Common Alternatives

Versus monofacial panels. A one-sided panel only collects light on the front. The MEGA 590 Bifacial can add rear-side gain when mounted above a reflective surface.

Versus the MEGA 600 Bifacial. The two panels share a Rich Solar spec sheet, size and weight. The MEGA 600 Bifacial is rated for 10W more per panel.

Versus smaller residential panels. Fewer, larger panels mean fewer modules, mounts and connections for the same array size, but each panel is 89.7 x 44.6 inches and 70.6 pounds.

Is This Panel the Right Fit

• Quantity. Choose a pallet of 8, 10, 12 or 36 panels. Rich Solar ships this panel by pallet only.
• System design. Each panel has a 52.5V open circuit voltage and a 14.2A short circuit current. Size strings to stay within your inverter or charge controller's limits.
• Fusing. The maximum series fuse rating is 25A, and the maximum system voltage is 1500VDC.
• Handling. At 70.6 pounds and 89.7 inches long, plan handling and racking for large-format modules.

This may be a good fit if

• You are building a large residential, agricultural or commercial array
• You can mount panels where the rear side will see reflected light
• You want UL-certified panels with a 25-year output warranty
• You can receive a full pallet of panels

Common Questions

How Much Extra Power Does the Rear Side Add?

Rich Solar rates it for up to 25% additional rear-side power gain. The actual gain depends on surface albedo, which is how much light the surface under the panel reflects.

Can I Buy a Single Panel?

Rich Solar ships this panel by pallet only. This listing offers pallets of 8, 10, 12 or 36 panels. Contact our team about other quantities.

Does It Work With Grid-Tie Inverters?

Yes. Rich Solar lists the panel as compatible with both on-grid and off-grid inverters.

What Is the Warranty?

Rich Solar provides a 25-year output warranty and a 10-year workmanship warranty on each panel.
