Battery vehicles on 'longest and greenest' world tour
Battery vehicles from Australia, Germany and Switzerland have set off on the "longest and greenest" round-the-world drive to promote emissions-free transport.
Simple Solar Update - Inexpensive Lead-Acid Battery
Solar Power Questions:
Which configuration for a solar cell will power a battery faster, parallel or serial?
Why does one configuration work faster than the other? Can someone explain this to me please?
If all variables were equal, and the two solar panels sat in the same sun which configuration is likely to power a battery more quickly, the one with parallel configuration or serial configuration?
depends on the battery voltage and the solar cell voltage.
You need the solar cell output to be a few volts higher than the battery voltage, so you put the cells in series until the voltage is high enough. Then you can put another equal string(s) in parallel to get more current.
It gets complicated by the fact that the solar cell voltage varies with load and with amount of sun, so in practice you may need more in series to get to the proper voltage.
