Rich Solar MEGA 400 Watt Monocrystalline Solar Panel

The Rich Solar MEGA 400 Watt Monocrystalline Solar Panel Gives Large Off-Grid and Grid-Tie Arrays 400W per Panel in Pallet Quantities

The Rich Solar MEGA 400 Watt Monocrystalline Solar Panel is a 24V off-grid panel that delivers 400W from 108 monocrystalline cells with 10 busbars and up to 23.2% efficiency. Each panel measures 67.8 x 44.7 x 1.2 inches, weighs 45.2 pounds and is certified to UL 61730, IEC 61215 and CSA C22.2. It works with both on-grid and off-grid inverters.

This listing sells the MEGA 400 by the pallet, in quantities of 8, 10, 12 or 36 panels, for 3,200W, 4,000W, 4,800W or 14,400W of total rated power. Rich Solar ships this panel by pallet only. For other quantities, contact our team.

Rich Solar MEGA 400 Watt Monocrystalline Solar Panel Features

10-Busbar Monocrystalline Cells

The 108-cell layout uses 10-busbar monocrystalline cells with up to 23.2% efficiency to deliver a reliable 400W per panel. The 0 to +5W power tolerance means each panel delivers at least its rated output at standard test conditions.

Strong Low-Light Performance

The cells and 3.2 mm AR-coated tempered glass capture more sunlight on cloudy days and at dawn and dusk, so the array keeps producing when conditions are less than ideal.

Tested for Long-Term Reliability

Every panel is PID resistant and 100% EL inspected to help prevent microcracks. Rich Solar also tests the panels for UV exposure, thermal cycling and humidity freeze.

Built for Snow and Wind

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.

Ready for Racking

The lightweight, strong, corrosion-resistant anodized aluminum frame has 8 pre-drilled mounting holes for 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 limited power output warranty and a 10-year workmanship warranty.

Real-World Applications

Off-grid homes. Build a ground-mounted or roof-mounted array sized for a full household battery bank.

Grid-tie residential systems. Rich Solar lists the panel as compatible with on-grid inverters.

Farms and ranches. Power well pumps, barns, shops and outbuildings far from the grid.

Commercial sites. Supply off-grid buildings, equipment yards and remote facilities.

How It Compares to Common Alternatives

Versus buying panels one at a time. A pallet gives you 8 to 36 identical panels, so every string in the array is matched for voltage and current.

Versus the MEGA 410. Both share a Rich Solar spec sheet. The MEGA 410 is rated for 10W more per panel.

Versus large bifacial panels. Bifacial panels can add rear-side gain over reflective ground but are larger and heavier. The MEGA 400 is a single-sided panel at 45.2 pounds, suited to roofs and racks where the rear side would not see much light.

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 37.1V open circuit voltage and a 13.7A 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.
• Space. Plan for 67.8 x 44.7 inches and 45.2 pounds per panel.

This may be a good fit if

• You are building a large off-grid or grid-tie array
• You want 400W per panel to keep module count down
• You want UL-certified panels with a 25-year output warranty
• You can receive a full pallet of panels
