Product description

[POWER YOU CAN EXPECT] 400W is the lab rating (STC); real-world output depends on sunlight, heat, shade, cable length/gauge, and the controller—MPPT recommended.
[LONGER BUILT-IN LEADS] 3 m (9.84 ft) MC4 leads reach farther than many short-lead panels, often eliminating add-on extensions and extra connectors. Fewer joints = fewer issues.
[12V: PARALLEL PRIORITY] For 12 V systems, choose parallel wiring for smoother charging; use series only with high-input controllers.
[REPLACES 4×100W] One 400W unit means less hardware to buy and wire, fewer branch pieces, and fewer chances of a poor connection.
[WEATHER-RESISTANT CONSTRUCTION] Tempered glass panel and aluminum frame with a sealed junction box—made for outdoor rain/splashes in yard settings.
[MOUNTING FRIENDLY] Pre-drilled holes align with common Z-brackets, rails, and tilt mounts for sheds and greenhouses.
[IF DAMAGED, WE’LL SORT IT] Check upon delivery. Should a panel arrive damaged, send us a message via Your Orders for a fast resolution.
