hi I'm learning electronics circuits stuff and I 'm trying to wire a small solar panel to power a small timer or a small handheld fan and am having trouble.
I disassembled the solar panel from a calculator. Both the timer and the fan are from a dollar store. I use multimeter to measure the solar panel and got roughly 2v under full light. The fan will run on two 1.5v AA batteries and the timer will run on one 1.5v AA battery.
I wired the solar panel to the timer and nothing happens. For the fan I tried two solar panels but the fan doesn't run. I wired the two little calculator solar panels in series and it reads 3v. The two solar panel setup produces much more voltage than the battery and yet does not power the timer or the fan, why is that ?
