Review on AOSHIKE Electric Materials Photovoltaic 53X30MM by Roshan Schram

I received two sets of AOSHIKE 5V 30mA 53mmx30mm Solar Panels (10pcs) for a STEM project in an elementary school classroom. All 20 panels I received were intact with no uninterrupted solder joints on the pins. As with solar panels, the voltage depends on the intensity of the light. You can use them in series or parallel but a diode would be a good idea to limit reverse current. 30mA max isn't much, so be reasonable in your expectations. Essentially, the STEM project was about having a solar panel drive a single LED in a T-shaped package (which it can). Also, you need to use more than one panel.
