Review on 10Pcs AOSHIKE Micro Solar Panels 2V 130mA - DIY Photovoltaic Solar Cells for Toys, Projects, Epoxy Plate by Jason Man

I bought these for the Raspberry Pi Offline Wiki and they're great if you know how electricity works. After seeing all the bad reviews for 1.5v motors I knew a lot of people would be discouraged. . So here's a little lesson about electricity, there are three main parts of electricity (ohm's law): voltage, current and resistance. Voltage is the 'push' of electricity and amperage is flow, so if you put a 1.5v motor on a 2v solar cell it WILL NOT WORK, not because of the product but because you are stupid probably need a higher amperage. than the 130mA this provides (the reason we use batteries and charge controllers) if you want this to work you need to increase the current to the required amount for the motor. I would suggest putting two in parallel as this increases the current in series the voltage! To be honest it scares me how TEACHERS ruin everything when it's that simple after you google ohms law for 3 seconds you will figure out how to get the engine working.
