Encapsulated mini solar panel with 6" red and black leads (no soldering required). Great for science projects or solar energy lessons. Connect together in series to increase voltage, in parallel to increase current. Output is 1.5 volts, 400mA. 3.75" X 2.5". Works perfectly with Kidders 500 watt halogen lamps (Cat# 83-1120-75). Light source needs to be 150 watts or more. Best paired with a low voltage motor (Cat#80-3545-SO)
