The Rich Solar MEGA 35 35 Watt 12V Solar Panel (model RS-M35) is a long, narrow rigid panel for 12V off-grid systems. Its 32 monocrystalline cells sit behind 3.2 mm AR-coated tempered glass in an anodized aluminum frame that measures 33.0 x 9.5 x 1.2 inches and weighs 5.7 pounds.
Rich Solar builds it for RVs, vans, truck campers, boats and cabins. Pre-attached MC4 leads, an IP67-rated junction box and four pre-drilled mounting holes make it straightforward to install, and it carries a 25-year power output warranty and a 10-year workmanship warranty.
The 32-cell layout uses 6-busbar monocrystalline cells with up to 23.2% cell efficiency, for a module efficiency of 17.3%. At its maximum power point the panel delivers 17.9V and 1.96A. The 0 to +5W power tolerance means each panel is rated to deliver at least 35W at standard test conditions.
At 9.5 inches wide and 33.0 inches long, the MEGA 35 fits narrow mounting areas that a wider panel can't use. The lightweight frame keeps it at 5.7 pounds, so it is easy to handle during installation.
High-transmission, AR-coated 3.2 mm tempered glass lets in sunlight and protects the cells. Rich Solar designs the panel to withstand salt, ammonia, sand, high temperatures and humidity, and rates it for 5400 Pa positive and 2400 Pa negative mechanical load, which it describes as snow and wind loads. The operating range is -40°F to +185°F.
Rich Solar designs the MEGA 35 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.
Each 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.
Pre-attached #12 gauge (4.0 mm²) leads, 35.4 inches each, end in MC4 connectors, and both the junction box and connectors are rated IP67. The connectors support series and parallel wiring.
Boats. Rich Solar lists marine systems among the panel's uses, and the 9.5 inch width helps where open space on board is narrow.
Vans and truck campers. Add 35W of charging to a 12V system where the open roof area is long and narrow.
Trailers and RVs. Add a compact panel to top up a 12V house battery while you travel or camp.
Cabins. Add a small panel to a 12V off-grid battery system at a cabin.
A wider panel can hold more cells, but it needs a broad, open mounting area. The MEGA 35 keeps the width to 9.5 inches, so it fits long, narrow spaces where a square panel won't.
A flexible panel is made to follow curved surfaces. The MEGA 35 is a rigid panel with 3.2 mm tempered glass and an anodized aluminum frame, rated for 5400 Pa and 2400 Pa loads, and it mounts with brackets, poles or tilt mounts through its pre-drilled holes.
Make sure your charge controller accepts the panel's 21.6V open circuit voltage and 2.13A 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. Keep any series string under the 1000VDC maximum system voltage, and note the 10A maximum series fuse rating.
The four pre-drilled holes work with Z brackets, tilt mounts, pole mounts and ground installations. Mounting hardware isn't included, so plan for brackets or a mount.
The panel measures 33.0 x 9.5 x 1.2 inches (838 x 241 x 30 mm) and weighs 5.7 pounds (2.6 kg).
Yes. The connectors support both series and parallel configurations. Keep the total within your charge controller's limits and the panel's 1000VDC maximum system voltage.
Rich Solar lists the MEGA 35 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 35 35 Watt 12V Solar Panel combines 6-busbar monocrystalline cells, AR-coated tempered glass and IP67-rated connections in a 9.5 inch wide frame for boats, vans, trailers and cabins. If you'd like help matching it to a charge controller, battery or mount, the Outbound Power team is happy to help.
