MEGA 400 | 400 Watt Solar Panel | Premium Grid-tie or Off-grid Solar Panel for Residential, Commercial, Agriculture

Power up your home backup system with the Rich Solar MEGA 400, a high-efficiency 400-watt monocrystalline solar panel designed for maximum performance and durability. Whether you’re building a robust solar setup for your RV, cabin, or residential needs, the MEGA 400 delivers exceptional power output and reliability in a sleek, compact frame.

Unmatched Efficiency with Half-Cut Cell Technology

The MEGA 400 features advanced half-cut cell technology, which not only boosts efficiency but also improves shade tolerance and minimizes power loss. With 108 monocrystalline half-cut cells, this panel captures more sunlight and converts it into power more efficiently than traditional designs.

Built for Strength and Longevity

Durability is at the core of the MEGA 400. Its rugged anodized aluminum frame and high-transparency tempered glass provide exceptional protection from the elements. Rated for 2400 Pa wind loads and 5400 Pa snow loads, this panel is designed to perform reliably in extreme weather conditions, ensuring long-term performance wherever you deploy it.

Lightweight Design with Easy Installation

Despite its robust build, the MEGA 400 weighs just 43.9 lbs, making it easy to handle and install. Pre-drilled holes in the frame allow for flexible mounting options, and the included MC4 connectors support a quick, secure connection to your existing system. Whether you’re upgrading or starting fresh, installation is simple and straightforward.

Maximum Output, Minimal Footprint

With an impressive 20.97% module efficiency and a compact footprint (67.8″ x 44.6″), the MEGA 400 packs serious power without taking up too much space. It’s ideal for installations where space is limited but power demand is high—like RVs, tiny homes, and residential rooftops.
