Dude show something actually useful like how to test if wires in your house (lets say behind a thermostat that you want to replace) are hot still after you've turned off what you think are the right power switches on your house's power box. Showing how to use a multimeter with a battery or solar powered panel does me no good....I learn nothing that is practical to every day household maintenance here.
Test the wires as you would the solar panel or the battery. Be very careful and touch one probe to the ungrounded(usually black or red) wire and one to the grounding(bare copper) or grounded(white). If you are just testing for safety I would recommend getting a small non-contact voltage detector and using that. Remember to test it on a live circuit every time before you use it.
if a solar cell is rated at 1V and 1Amp, this is the max it will read when the solar cell is facing directly at the sun. if you leave your solar cell fixed in one direction then the amp reading will be proportional to the amount of sunlight shining on the cell, which varies throughout the day.
so he got only 1.2 amps when supposed to get 2.1 amps. That is a huge difference. I guess you have to measure it when the sun is highest in the sky to get that reading, and it's the only time of the day that it will produce 2.1 amps. So even if solar cells are rated at lets say 4 amps, it means that 4 amps only for about 2 hours a day, 11am to 1pm, then it falls down like to 3 and 2 amps afterwards. Do I understand this right?
My name is Joya, and I live in Virginia State, I am really interested to learn more about the solar energy, I mean to learn more depth with more detail "professional level. Is there any class or any book or video to teach me how to become a solar expert? Please, Please, I need your advice.
Good job...I just wasted a lot of time reading all kinds of nonsense about trying to measure the panel and this was just the right info. Thanks
