Re: Science Fair Project
Using a multimeter, as LH2 suggests above to measure just short circuit current could also work. Assuming a 12v nominal panel, current shouldn't be more than ~1 amp, which most multimeters should be …1 · -
Re: Science Fair Project
It might also be kind of fun to rig up a simple sundial sort of thing (like a straw stuck vertically on a flat base) and track the shadow to get a visual record of the suns path and angles. Maybe use…1 · -
Re: Science Fair Project
For tracking, there will be a horizontal track, which changes from morning to night as the sun goes from east to west, and a vertical track, which increases until solar noon, then decreases until sun…1 · -
Re: Science Fair Project
The voltage reading may be influenced by the type of controller, but in general: - Open circuit voltage (with no load) will be pretty constant in a wide variety of light, and vary a bit with cell tem…1 · -
