How much power does it actually produce?

Renogy rates it at 300W and about 960Wh per day under good sun. Real output depends on angle, clouds and shade, so expect less on overcast days.

Will it work with my portable power station?

It uses IP68 connectors that fit most portable power stations and solar-ready batteries. Check your station's input connector and voltage limit before buying.

Is it really waterproof?

It carries an IP67 rating and an ETFE coating, and Renogy says it handles hail, snow and temperatures from -40°F to 185°F. The junction box and connectors should still be kept out of standing water.

How heavy is it to carry?

It weighs 18.74 lbs, about 17% less than a standard 300W folding panel. That is manageable for short carries but noticeable on long walks.

Does it need a charge controller?

Yes, if you connect it directly to a battery rather than a power station with a built-in controller. A compatible MPPT controller protects the battery and improves yield.

Unfold it, prop the kickstands and plug in; Renogy says about one minute with no tools. You will still want to angle it toward the sun for best output.
