The Rich Solar MEGA 50 ONYX 50 Watt 12V Solar Panel Brings N-Type TOPCon Efficiency to a 7.3 Pound Panel for Boats, Vans and Trailers
The Rich Solar MEGA 50 ONYX 50 Watt 12V Solar Panel is a compact, rigid 12V off-grid panel that delivers 50W from 30 N-Type TOPCon cells with 18 busbars and up to 25.3% efficiency. It measures 23.6 x 18.1 x 1.2 inches and weighs 7.3 pounds, so it fits small mounting areas on boats, vans, trailers and sheds.
The panel is certified to UL 61730, IEC 61215 and CSA C22.2. Pre-attached 12 AWG leads, 2 ft each, with IP67 MC4 connectors and an IP67 junction box make it easy to wire to a charge controller.
Rich Solar MEGA 50 ONYX 50 Watt 12V Solar Panel Features
18-Busbar N-Type TOPCon Cells
The 30-cell design uses 18-busbar N-Type TOPCon cells with up to 25.3% efficiency. Rich Solar guarantees a positive power output of 0 to +5W, so the panel delivers at least its rated 50W at standard test conditions.
Strong Low-Light Performance
The cells and 3.2 mm AR-coated tempered glass keep producing on cloudy days and at dawn and dusk, which helps a small battery stay topped up.
Built for Harsh Environments
The panel is designed to withstand salt, ammonia, sand, high temperatures and humidity. It is certified for 2,400 Pa wind loads and 5,400 Pa snow loads, and the IP67 junction box and connectors keep out dust and water.
Premium Quality Checks
Every panel goes through 100% EL inspection, and the cells are PID resistant for long-term output.
Light and Easy to Mount
At 7.3 pounds, the panel is simple to handle. The lightweight, strong, corrosion-resistant anodized aluminum frame has 8 pre-drilled mounting holes for Z brackets, tilt mounts, pole mounts and ground installs.
25-Year Output Warranty
Rich Solar backs the MEGA 50 ONYX with a 25-year output warranty and a 10-year workmanship warranty.
Real-World Applications
Boats. Maintain a starting or house battery at the dock. The panel is designed to resist salt and humidity.
Vans and truck campers. Fit a small panel into limited roof space.
Trailers. Keep a trailer battery charged between trips.
Gates, sheds and monitoring. Charge a 12V battery for a gate opener, shed light, camera or sensor.
How It Compares to Common Alternatives
Versus the MEGA 50. The standard MEGA 50 uses 10-busbar monocrystalline cells with up to 23.2% efficiency and weighs 8.0 pounds. The MEGA 50 ONYX uses N-Type TOPCon cells with up to 25.3% efficiency in a lighter 7.3 pound panel.
Versus the MEGA 50 FLEX. The flexible version is lighter and bends to fit curves, but carries a 1-year warranty. The rigid MEGA 50 ONYX has glass, a frame, UL certification and a 25-year output warranty.
Versus a 100W panel. A 100W panel doubles the output but needs much more space. The MEGA 50 ONYX suits small spaces and light-duty charging.
Is This Panel the Right Fit
-
Charge controller. Use a 12V PWM or MPPT charge controller between the panel and your battery.
-
Wiring. With a 22.8V open circuit voltage and 2.87A short circuit current, panels can be wired in series or parallel. Stay within your controller's limits.
-
Fusing. The maximum series fuse rating is 10A.
-
Lead length. The pre-attached leads are 2 ft each, so plan an extension cable if the controller is farther away.
This may be a good fit if
- You need a small, light 12V panel for a tight space
- You want N-Type TOPCon cells in a compact size
- You want UL certification and a 25-year output warranty
- You maintain a boat, trailer or equipment battery
Common Questions
Do I Need an Inverter to Charge My Battery?
No. You only need a charge controller to charge a battery. An inverter is needed only to run AC appliances from the battery.
Can the Panel Drain My Battery at Night?
Not when a solar charge controller is installed. The controller prevents reverse current from draining the battery.
Will It Work in Winter?
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.
Does It Require Roof Penetration?
Not always. Panels can often be mounted on the roof using a sealant, or installed on the ground instead.
