    The four solar cells were about 6.5 inches by 1 7/8 inches each for a calculated total of 48.75 square inches. A square meter is a little under 40 inches by 40 inches. One percent of it is a little under 4 inches by 4 inches or 16 square inches. 48.75 divided by 16 is a bit more than 3. The standard light power for solar cells is the AM 1.5 global solar spectrum sunlight standard = 1,000.4 Watts per square meter. One percent is about 10 Watts and three percent is about 30 Watts so the 30 Watts in

    the usb on the panel is faulty.. very loose. You have to wiggle it about to get proper contact.. but it doesn't stay working for long maybe 2 seconds then stops.
