Small Solar Panel 37 x 33mm, 6.7V, 20mA | ||||||||||||||||||||||||||||||||||||||||||||||||
![]() | This is a great solar panel which outputs a high enough voltage to directly drive electronic circuits or charge batteries. The panel is built on a sturdy PCB substrate and is epoxy encapsulated to withstand rough handling. The PCB includes solder pads to populate a simple "Miller Solarengine" which lets you pulse-power high current draw devices, like motors and electromagnets, that would otherwise require a large number of parallel cells. The addition of the circuit pads does not interfere with using this as a simple solar panel. The panel is really two sub-panels connected in series. The series connector is accessible as a PCB trace on the back. You can cut that trace and wire the cells in parallel to turn this into a 3.3V, 80mA panel. Specifications:
