50W Solar Panel Kit 12V Trickle Charger

A 50W monocrystalline solar panel kit designed for trickle charging 12V batteries in boats, RVs, trucks, and caravans. The panel delivers efficient, maintenance-free charging from sunlight alone, making it ideal for applications where mains power isn’t available.

The kit features 23% high-efficiency crystalline silicon cells across a compact 360 × 330 × 3mm frame. Maximum open circuit voltage reaches 22V, with an 18V working voltage and 19.9% module efficiency. These specs ensure reliable performance across diverse weather conditions.

Dual USB ports allow simultaneous charging of two devices—phones, tablets, or power banks—while the main panel manages battery maintenance. The flexible design fits various installation scenarios including curved surfaces and compact spaces where traditional panels won’t work. Lightweight and portable, the panel includes mounting brackets, multi-function charging cables, a car charger adapter, and clip cables for secure attachment.

Ideal for camping, motorhome trips, hiking, boating, and emergency power situations. The kit operates without fuel, moving parts, or ongoing maintenance—just position it in direct sunlight and it begins charging automatically.
