I purchased the Kickass 12V 300WATT Super Thin Portable Solar Panel. The cable is good quality so I purchased the 10m cable to go with it so we can catch the sun and camp in the shade. These panels put out 3 times the power of my old glass panels and weight half the weight. Even with the two kids constantly smashing my 3 batteries in the camper with iPhones, iPads, Bluetooth speakers and lights plus the usual fridge freezer and camp lights, these solar panels keep my batteries topped up every day.
