Product Information
200W 12V Solar Panel for RVs, Cabins and Boats
The MEGA 200 Onyx produces roughly 800–1000Wh on a clear day. That is enough to keep lights, a fridge, water pump and device charging going in RVs, cabins and boats.
It wires straight to a 12V battery through a PWM or MPPT charge controller. Add a second or third panel in parallel as your power needs grow, or move to a 24V panel if you are building a larger bank.
Anodized aluminum frame – lightweight, strong, and corrosion-resistant. MC4 connectors with 3 ft pre-attached cables for quick and easy installation. It takes standard Z-brackets on a flat roof, or a tilt mount to angle it toward winter sun. The panel measures 58.7 x 26.8 x 1.2 in and weighs 24 lb.

Frequently Asked Questions
How much power does this panel produce per day?
Roughly 800–1000Wh on a clear day, based on 4–5 peak sun hours. Expect less in winter, in cloudy weather, or if the panel is not angled toward the sun.
Do I need a 12V or 24V battery for this panel?
This is a 12V panel, so it pairs most simply with a 12V battery bank through a PWM or MPPT controller. You can also feed a 24V or 48V bank by wiring panels in series into an MPPT controller — check the controller's maximum input voltage first.
How do I mount it?
The frame has pre-drilled mounting holes that take Z-brackets for a flat roof, tilt mounts to angle it toward winter sun, or pole and ground mounts for a fixed array. Our team can advise on 1-332-291-6885.
