Monocrystalline 300W Solar Panel Kit

A field-tested portable solar solution featuring a 12W–15W monocrystalline panel (280 x 280 mm) with frosted PET surface, 18V operating voltage, and 21.6V open-circuit voltage. Paired with a 50A/300W PWM controller (130 x 70 mm), it supports dual USB-A outputs and DC5521 battery clamps for direct 12V connection. Includes cigarette lighter cable, four suction cups, two outdoor buckles, and full mounting flexibility. Total package weight is 650g; dimensions are 30 x 29 x 3.5 cm. Integrated 5V regulation protects connected devices from voltage instability, and the PET layer enhances resistance to scratches, moisture, and UV-induced yellowing — critical for longevity across UK seasonal use.
