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
12V 50W Monocrystalline Small Solar Panels
A 50W 12V panel with connector leads already fitted. Small, cheap and genuinely useful in the places a full array is overkill — maintaining a battery over winter, running lighting on a trailer, or as a first panel to learn on.
- 50W, 12V nominal
- Male and female connector leads fitted
- Advanced encapsulation for outdoor durability
- Suits battery maintenance, lighting and small off-grid loads
What 50W actually does
On a good UK summer day a 50W panel might bank 150–250Wh; in December, closer to 20–40Wh. That is nowhere near enough to run a conversion, and exactly right for holding a leisure or starter battery at float while the van is parked — which is the cheapest insurance against a dead battery in spring.
Expanding later
The fitted connectors make it easy to add to, but mixing panel sizes in one string causes the whole string to work at the weakest panel's current. If you think you will expand, either buy matched panels or plan to wire additional panels in parallel through their own controller input.
Before you order
Renogy supply the panel alone — no controller, brackets or extension cable. You will need at minimum a charge controller and a way of fixing it down before it does anything useful.
