400 Watt Solar Panels

400 Watt Solar Panels

A 400 watt solar panel makes roughly 1.6 to 2 kWh on a good sun day, enough to keep a 12V camping fridge or a mid-size power station topped up, and a handful of them can run a cabin or feed a whole-home battery bank. These are the 400W-class panels we carry today, from a single folding panel to multi-panel packs.

Pick the right format

• Portable and folding: the Nature's Generator 400W Folding Solar Panel sets up on its own stand for power stations, camping, and backup.
• Rigid 2 and 4 packs: 410W monocrystalline panels for roof or ground mounts on a cabin or shed.
• Larger arrays: Rich Solar MEGA 400 and MEGA 410 panels in 8, 10, and 12 panel packs for off-grid homes and grid-tie builds.

Match panels to your system

Check the panel's open-circuit voltage against your charge controller or inverter input before you wire panels in series. Pair them with a solar charge controller and a battery from Home Battery Backup, or browse every panel in Solar Panels. Need help sizing an array? Call 888-855-7286.
