Rich Solar MEGA 250 | 250 Watt Solar Panel

The MEGA 250 is a 250-watt, 12-volt rigid solar panel designed for off-grid and mobile power systems. Its compact footprint makes it suitable for space-limited installations on RVs, vans, trailers, boats, cabins, and motorhomes.

N-Type TOPCon cells, a half-cut 16-busbar design, and AR-coated tempered glass support efficient light capture and low-light performance. Bypass diodes help maintain stable operation in partial shade.

The panel has a corrosion-resistant anodized aluminum frame, pre-drilled mounting holes, and plug-and-play solar connectors. It is designed to withstand demanding outdoor conditions, including wind, snow, hail, moisture, salt, sand, heat, and humidity.
