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
200W N-Type Bifacial Solar Panel
200W N-type bifacial, 19.9% efficient, IP68, with a 25-year output warranty. Eighty cells in a 1312 × 765mm frame — the workhorse rigid panel for a medium or long-wheelbase van roof.
- 200W at STC, 19.9% module efficiency
- N-type bifacial, 80 cells
- Vmp 25V, Voc 29.6V, Imp 8A, Isc 8.7A
- IP68, anodised aluminium frame, 2 bypass diodes
- Temperature coefficient of Pmax −0.32%/°C
- 10.3kg, 1312 × 765 × 30mm, 1m output cables
The voltage sits between the two camps
Vmp of 25V is above a 12V nominal panel and below a true 24V one. In practice that means MPPT: a PWM controller would waste the headroom. It also means two in series reaches around 59V open-circuit, which suits a 95V controller comfortably and keeps roof cable current low.
Bifacial, honestly
The rear face only contributes where light can reach it. On Z-brackets above a light-coloured roof you will see a small gain; bonded flat you will see none. Buy it for the N-type cells, the −0.32%/°C temperature coefficient and the 25-year warranty — the bifacial rear side is a bonus if your mounting happens to suit it.
Before you order
10.3kg each, and 1312 × 765mm is a substantial rectangle — two of these is most of a van roof once you allow for a vent. Output cables are a useful 1m, which often saves buying extensions. Maximum series fuse rating is 25A.
