GridGuard Bifacial Monocrystalline Solar Panel, 200W-400W, MC4 Connectors

Product details

2-Year GridGuardPlus Warranty included. Every item we sell is backed by our two-year warranty. Questions? Call 1-800-680-4080.

This rigid bifacial monocrystalline solar panel is made for higher-output charging in off-grid systems, RVs, sheds, farms and rooftop setups, and for recharging compatible portable power stations. Dual-sided cells capture light from both the front and the rear, and pre-fitted MC4 connectors make hookup simple. Choose a single 200W panel or a 400W set.

Solar panels turn sunlight into usable power, so you can recharge without the grid. Pair the panel with a compatible charge controller, battery or power station to keep your gear running wherever the sun reaches.

What to expect from the sun

On a clear day with about four hours of strong sunlight, a 200W panel typically yields roughly 600Wh of usable energy after real-world losses, and a 400W set roughly 1,200Wh. Cloud, haze, shade and a poor angle will reduce that. Bifacial panels can add extra output from reflected light, depending on how they are mounted.

Good to know

A solar panel only produces power while it is in sunlight, and its rated wattage is what it can deliver under ideal conditions, so real-world output will usually be lower. These are rigid panels and need to be mounted securely. Before you order, make sure the panel's voltage, current and MC4 connectors are compatible with the charge controller, power station or battery you plan to charge. An MC4 adapter cable may be needed for some power stations.

Who this is not for

Anyone who wants a foldable panel they can carry and set up quickly, or whose power station has no MC4-compatible solar input.

Setup and care

• Mount on a flat, secure surface angled toward the sun
• Connect to a compatible charge controller or power station before leaving it in the sun
• Keep the panel clean and free of shade
• Secure it against wind and inspect connections periodically

Frequently asked questions

What does bifacial mean?
Both sides of the panel can collect light, so it can capture extra reflected light from the rear when mounted with open space behind it.

Does it work on cloudy days?
Yes, but at much lower output. Direct sun at a good angle gives the best results.

Will it work with my power station or battery?
It depends on the connector and voltage. Send us your model before you order and we will confirm, or call 1-800-680-4080.

Which option should I choose?
Pick 200W for a single panel. Choose a 400W set if your system can accept the higher input and you want faster charging.
