Nice and well built small solar cell for tiny circuits, experiments and recharging of SMALL capacity batteries. But specs on description are very wrong. As measured, the device gives under direct summer sun a maximum of 6,5V, but a current of 0,035A, not 0,35A as staded on description. So, applying Ohm this means a solar panel alone can give a maximum of 0,5W, not 2W. To get 2W you would need to put 4 of these together on paralel. I bought this one for building a solar automatic garden light and I am afraid the power it gives is not enough for fully recharging the small battery during daylight. However, nice panel for the price you get.
