Review on 🌞 Compact Sunnytech 0.5W Solar Panel Module - DIY Charger B016 (5V, 100mA) by Hunter Siemon

This provides the signaling voltage for a solid state relay requiring less than 5 volts at about 10mA. I can't tell if it will deliver the maximum power rating or how long it will last as it was only used for about a week. Of course it was a simple and convenient source of signal voltage to control a large solar powered borehole pump via a solid state relay with a small float switch. I couldn't find a float switch that could handle 5 amps at 180 VDC!
