How buying this works
Roam Wired does not stock this item. The button above hands you over to the seller's own shop, where you place the order, pay and arrange delivery directly with them. Nothing is added to a Roam Wired basket, and we never see your payment details.
We list it because it is the part our calculator would specify for a build like yours, not because we make the most on it. How we make money
Delivery and returns
Delivery cost, delivery time and the returns window are set by the seller, not by us, and Roam Wired's own £10 / free-over-£250 UK delivery does not apply here. Check their delivery and returns terms on their product page before you order.
Your consumer rights, including the 14-day right to cancel a distance sale, are against the seller who took your order.
Warranty and support
The manufacturer's warranty is handled by the seller you buy from. If something fails, raise it with them and quote their order number — we cannot open a claim on your behalf.

Overview
320W N-Type Bifacial Solar Panel (2-Pack)
320W panels at 20.5% efficiency, sold in pairs. Large-format bifacial modules — 1775 × 880mm and 16.7kg each. This is motorhome, horsebox and static installation territory rather than a panel van roof.
- 320W at STC (0 to +15W positive tolerance)
- 20.5% module efficiency, N-type bifacial
- Vmp 30.29V, Voc 35.04V, Imp 10.57A, Isc 10.94A
- 1500V DC maximum system voltage
- 16.7kg each, 1775 × 880 × 35mm
- Sold in 2, 4, 6 and 10 panel packs
Measure before you fall in love
1775 × 880mm is 1.56 square metres per panel. Two of these will not fit across most panel van roofs, and at 16.7kg each the pair is over 33kg before mounting hardware. On a coachbuilt motorhome, a horsebox roof or a ground-mounted array they make complete sense; on a Transit Custom they do not.
Positive power tolerance
Renogy quote 320W with a 0 to +15W tolerance, meaning a panel will never test below its rating and may exceed it. That is a quality signal — cheaper modules are commonly specified with a negative tolerance, so a "320W" panel might genuinely deliver 305W.
Before you order
At 10.57A operating current per panel, two in parallel is over 21A — size the controller and the roof cable for it, and remember the 25A maximum series fuse rating. Two in series reaches 70V open-circuit, so check your controller's input window.
