Review on AOSHIKE Polycrystalline Silicon Photovoltaic Charger by Hunter Schneider

All the above information is correct. Fragile, thin and the performance is about right. If I wanted more power I would buy an array. They are lined up on the sunny side of the mini blinds that need to be powered by a motor. A limitation. Check the cell output voltage before use. The second one I picked up had a 27mV output on the room lights. Others in the stack were in the 140mV range. With 100 pieces, I didn't find it important to knock off the sprocket or ask for a replacement. In fact, I ordered 200 to make sure I had enough for multiple projects.
