The Rich Solar MEGA 50 2026 50 Watt 12V Solar Panel (model RS-M50-26) is a compact rigid panel for 12V off-grid systems. It uses 30 N-Type TOPCon multi-busbar cells with up to 25.3% cell efficiency behind 3.2 mm AR-coated tempered glass, in an anodized aluminum frame that measures 23.6 x 18.1 x 1.2 inches and weighs 7.3 pounds.
Rich Solar designs it for RVs, vans, truck campers, boats and cabins. It is certified to UL 61730, IEC 61215 and CSA C22.2 standards and carries a 25-year power output warranty and a 10-year workmanship warranty.
The 30-cell layout uses N-Type TOPCon multi-busbar cells with up to 25.3% cell efficiency, for a module efficiency of 18.1%. At its maximum power point the panel delivers 18.2V and 2.76A. The 0 to +5W power tolerance means each panel is rated to deliver at least 50W at standard test conditions.
Rich Solar designs the MEGA 50 2026 to keep producing on cloudy days and at dawn and dusk. A power temperature coefficient of -0.35%/°C helps it hold output as the cells warm up.
High-transmission, AR-coated 3.2 mm tempered glass protects the cells while letting in sunlight. The panel is built to withstand salt, ammonia, sand, high temperatures and humidity, and it is rated for 5400 Pa snow loads and 2400 Pa wind loads. The operating range is -40°F to +185°F.
Every panel goes through 100% EL inspection, and the cells are PID resistant. Rich Solar uses a non-destructive cutting process to help minimize micro-cracks.
Twelve pre-drilled holes in the frame fit Z brackets, tilt mounts, pole mounts and ground installations. Pre-attached leads, 23.6 inches each, end in MC4 connectors, and both the junction box and connectors are rated IP67.
The MEGA 50 2026 is certified to UL 61730, IEC 61215 and CSA C22.2 standards, which helps when an installation calls for listed equipment.
Vans and truck campers. Add 50W of charging to a 12V house battery in a compact 23.6 x 18.1 inch footprint.
RVs and trailers. Help keep a 12V battery topped up between hookups.
Boats. Rich Solar lists marine systems among the panel's uses, and the IP67-rated junction box and connectors suit outdoor installations.
Cabins. Add a small panel to a 12V off-grid battery system.
A larger panel produces more power, but it needs more open roof or mounting area and adds weight. The MEGA 50 2026 keeps the size to 23.6 x 18.1 inches and 7.3 pounds for spaces where a full-size panel won't fit.
A flexible panel is made to follow curved surfaces. The MEGA 50 2026 is a rigid panel with 3.2 mm tempered glass and an anodized aluminum frame, rated for 5400 Pa snow and 2400 Pa wind loads, and it mounts through twelve pre-drilled holes.
Make sure your charge controller accepts the panel's 22.8V open circuit voltage and 2.87A short circuit current. Open circuit voltage rises in cold weather, with a temperature coefficient of -0.28%/°C, so leave headroom on the controller's input limit. The connectors support series and parallel wiring; keep any string under the 1000VDC maximum system voltage and note the 10A maximum series fuse rating.
Mounting hardware isn't included. Choose Z brackets for a flat roof or a tilt, pole or ground mount, and line them up with the pre-drilled holes.
The panel measures 23.6 x 18.1 x 1.2 inches (600 x 460 x 30 mm) and weighs 7.3 pounds (3.3 kg).
The pre-attached leads are 2.5 mm² (#14 gauge) photovoltaic cable, 23.6 inches (600 mm) long, with MC4 connectors.
Rich Solar lists the MEGA 50 2026 as compatible with both on-grid and off-grid inverters, as well as mainstream optimizers and mounting systems.
Rich Solar provides a 25-year power output warranty and a 10-year limited workmanship warranty.
The Rich Solar MEGA 50 2026 50 Watt 12V Solar Panel brings N-Type TOPCon cells, AR-coated tempered glass, IP67-rated connections and UL 61730 certification to a compact frame for vans, RVs, boats and cabins. If you'd like help matching it to a charge controller, battery or mount, the Outbound Power team is happy to help.
