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
100 Watt 12 Volt Flexible Monocrystalline Solar Panel
100W in a 3mm-thick, 2.4kg panel that bends to a curved roof. The flexible panel exists for one reason: it will follow the camber of a van roof and can be bonded down without brackets or drilling.
- 100W at STC, 15.7% module efficiency
- 2.4kg, 1093 × 582 × 3mm
- Vmp 20.7V, Voc 24.4V, Imp 4.84A, Isc 5.16A
- −40°C to 80°C operating range
- 12AWG output leads
- 5-year material warranty, 5-year 90% output warranty
Be clear about the trade-off
Bonded flat to a metal roof, a flexible panel has nowhere to dump its heat, and heat is what ages the encapsulation. The performance warranty is the honest signal here: five years at 90% output, against the twenty-five years quoted on Renogy's rigid panels. Choose flexible because you need the shape or the weight, not because it is cheaper.
If you do bond one down
Leave an air gap where you can — thin battens or a bead pattern that lets air move underneath makes a real difference to both output and lifespan. Use an adhesive rated for the roof material and the temperature range, and clean and prime properly: a panel that lifts at 60mph is a very expensive mistake.
Before you order
At 15.7% efficiency this takes more roof area per watt than the rigid N-type panels. If your roof is flat enough for brackets and you have the space, a rigid panel will produce more, last longer and cost less per watt.
