This is a nice small waterproof solar box, ideal for projects such as IoT, or where you don't need a lot of power generated to run the device

Plastic box is 100mm X 65mm X 36mm high

The solar panel is a 5V 150ma 0.75 watt unit.  There is a USB port inside the box.

I'd be happy to provide a better price for bulk purchase or bulk projects - just contact me.

If you need to store the energy, there are lots of small 'lipstick' Li-ion chargers that can charge in the sun and power your project at night. Or just wire up 3xAA NiMh and this panel will happily keep them topped up if the draw is not too high.
