The Rich Solar MEGA 220 Watt Solar Panel is a rigid 12V off-grid panel that delivers 220W from 64 monocrystalline cells with 16 busbars, with up to 22.8% cell efficiency and 20.7% module efficiency. It measures 55.1 x 30.0 x 1.2 inches, weighs 23.7 pounds and is certified to UL 61730, IEC 61215 and CSA C22.2.
Pre-attached 12 AWG leads, 4 ft each, with IP67 MC4 connectors and an IP67 junction box make it simple to wire to a charge controller or to other panels. Rich Solar backs it with a 25-year output warranty and a 10-year workmanship warranty.
The 64-cell layout uses 16-busbar monocrystalline cells with up to 22.8% cell efficiency and 20.7% module efficiency to deliver a reliable 220W. The 0 to +5W power tolerance means the panel delivers at least its rated output at standard test conditions.
The cells and 3.2 mm AR-coated tempered glass capture more sunlight on cloudy days and at dawn and dusk, so batteries keep charging when conditions are less than ideal.
Every panel is PID resistant and 100% EL inspected to help prevent microcracks. Rich Solar also tests for UV exposure, thermal cycling and humidity freeze.
The panel is rated for 5,400 Pa snow loads and 2,400 Pa wind loads and operates from -40°F to 185°F. The IP67 junction box and connectors keep out dust and water.
The lightweight, strong, corrosion-resistant anodized aluminum frame has 14 pre-drilled holes for Z brackets, tilt mounts, pole mounts and ground installs. The 4 ft leads give extra reach to neighboring panels.
Rich Solar lists the panel as compatible with both on-grid and off-grid inverters, so it can serve a mobile system or a stationary one.
RVs and travel trailers. Add 220W from one roof spot to keep house batteries charged.
Cabins and sheds. Charge a 12V battery bank for lights, fans, pumps and electronics.
Boats. Mount the panel on a hardtop to maintain house batteries.
Off-grid solar systems. Build a 12V array and add panels as loads grow.
Versus a 200W panel. The MEGA 220 adds 20W in a 55.1 inch long frame, which can fit roof sections where a longer panel will not.
Versus two 100W panels. Two 100W panels need two sets of brackets and more wiring. One MEGA 220 delivers more power from a single frame.
Versus flexible panels. Flexible panels are lighter and follow curves, but a rigid glass panel handles snow and wind loads and carries a longer warranty.
This may be a good fit if
No. You only need a charge controller to charge a battery. An inverter is needed only to run AC appliances from the battery.
Not when a solar charge controller is installed. The controller prevents reverse current from draining the battery.
Yes. Cooler conditions can improve solar panel performance. Keep the panel clear of snow, dirt and shade, since buildup will stop it from generating power.
Rich Solar rates MEGA Series panels to output more than 95% of rated power after 5 years, 90% after 10 years and 80% after 25 years, backed by a 25-year output warranty.
The Rich Solar MEGA 220 Watt Solar Panel delivers UL-certified 12V power in a durable, compact frame for RVs, cabins, boats and off-grid systems. At Outbound Power, we help customers pair panels with the right charge controllers, batteries and mounting hardware. If you have questions, our team is happy to help.
