| Sep 26, 2018 at 13:33 | comment | added | Adrian | @SomeoneSomewhere I am pretty sure I dont have measurement issues, I tried it on other power sources with similar expected output. If my panel is stuffed, is that normal I still read 6V ? | |
| Sep 26, 2018 at 13:30 | comment | added | Adrian | The panel is roughly 10 by 5 cm, or 4 by 2 inches | |
| Sep 26, 2018 at 13:26 | comment | added | Andy aka | What dimensions are the mini-panel? | |
| Sep 26, 2018 at 13:25 | comment | added | SomeoneSomewhereSupportsMonica | Due to V-I curve of PV panels, open circuit volts times short circuit amps is a pretty good indicator of maximum power output. | |
| Sep 26, 2018 at 13:24 | comment | added | SomeoneSomewhereSupportsMonica | You may have a measurement issue if you're getting 0 current. Make sure it's not over-range (often "0.L"), the leads are in the right sockets, and the fuse in the meter is intact. Alternatively, your panel could be stuffed. | |
| Sep 26, 2018 at 13:19 | comment | added | Adrian | @Puffafish The 1W is from the 'datasheet' of the panel. I didnt think about the initial current required to start the engine, that may be an issue indeed. Nonetheless, how can I measure the intensity output of my solar panel ? | |
| Sep 26, 2018 at 13:17 | comment | added | Adrian | @SomeoneSomewhere Full daylight on a sunny day, and I did short-circuited the panel with the multimeter, I dont anything but 0. The multimeter has no broken fuse or something, I tried it with a different power source and it displayed the intensity. | |
| Sep 26, 2018 at 13:16 | comment | added | Puffafish | Your first issue is that you've got a PV panel, which has 6V written on it. The 6V will only be there when there is no load (so no current) and under ideal lighting situations. Where did you get "1W" from? I am surprised you can find a mini solar panel with that much power, but that would only be provided under ideal lighting and at peak power (balancing voltage and current). As for why the motor won't turn, it will need a lot (as in twice the steady state) current to start it from a stand still. So you've over estimated your solar panel power and under estimated your required power. | |
