Do I need a charge controller with this kit?

Yes. The kit is panels only, so pair them with an MPPT or PWM charge controller sized for 640W and your battery voltage.

Can I wire the two panels in series or parallel?

Either works. Series suits MPPT controllers and longer cable runs; parallel keeps output up if one panel is shaded.

Are these panels waterproof?

The junction box is IP68 rated, so it handles rain and dust. The panels are designed for outdoor mounting, but connections should still be sealed.

What else do I need to install them?

Mounting brackets or rails, cabling, connectors, a charge controller, and a battery bank. None of these come in the kit.

Is 640W enough to run a cabin?

It covers lights, a fridge, and device charging in decent sun. Heavy loads like air conditioning or pumps need a larger array.

How do these compare with Renogy's 100W panels?

Two 320W panels give more power with fewer mounts and less wiring, but each panel is much larger and heavier to handle.

Our take on the Renogy 2pcs Solar Panel Kit 320W

This is a two-panel kit of Renogy 320W monocrystalline solar panels, each about 65.6 by 39.4 inches with an anodized aluminum frame and IP68 junction box. The pair totals 640W, which suits medium off-grid setups: a cabin, RV roof, or a small shed system with a charge controller and battery bank. Monocrystalline cells give strong output per square foot, and the IP68 rating means the junction box tolerates rain and dust. Against rigid rivals like Renogy's own 100W panels, these deliver more power per panel but weigh about 20 lb each, so roof mounting needs solid hardware and a plan for two large panels.
