I need some solar help. Answered
Ok so i dont know a whole lot about solar but i love the stuff. I also dont have alot of money (byproduct of not having a job) and wanted to make my own solar stuff for cheep. I posed another question about this but it was poorly writen so im putting more time into this one. I bought 9 solar powerd garden lights from dollar tree and one car phone charger. Now ive been led to belive that if i take a 9V battery and hook it up to that car phone charger it can deliver a safe and efficent charge to charge my phone. However since i dont want to spend a ton of money on batteries i deside to turn the consept solar. Ive found a few bumps along the way so if you have any advise please share it.
1. First ive been told that you need to connect a solar pannal to a load (for example a motor) to get an acccurate reading on your multimeter about the panals output voltage. Is this true?
2. I measured one of the solar pannals with a load in the sun and was told the cell emitted 1.5 volts. I then put five of them in serize and only got of reading of 2 volts not the 7.5 i was expecting.
3. I dont understand the imprtance of diodes when it comes to solar projects but as far as i know their just a safety procaution to help protect your cells against damage. Is this true and if so can i make my project work without them.
4. I dont know how to messure the amprage on my multimeter. Do i need a knew device or am i just missing something.
Thank you so much for takeing the time to help me out with this.
