Solar Yard Light

Solar Yard Light

if one small solar panel can charge 1.5 volts in one day?


i have 16 small yard light solar panels. If one is desighned to charge 1.5 volts in a day than 16 would = 24 volts woth of battery is this correct? and what is the best way to wire them together sereis to get volts, or do i want amps as long as it is at least 14 volts? Why doese wattage have a big play is it to get more amps out of your unit to charge faster, if that is so what is the formula to figure it out so i can go green to?

"charge 1.5 volts in a day" means what? volts are not a unit of charge, and volts are not per day.

But you are correct in that you need 14 volts or higher to charge a 12 volt lead acid battery. Probably should be higher, as solar panels have a very high output impedance. Voltage is important as the voltage from the panels has to be significantly higher than that of the battery, or instead of charging the battery, the battery discharges into the panel (although there is probably a diode in the circuit to prevent that. If not, be sure you put one in).

Simplistically, you can take wattage and divide by voltage to get current, and that is the current that will charge the battery, and the more current the faster it charges. In reality the math is more complicated, as it depends on the internal resistance of the panels, as well as the battery characteristics.
