    Depends on whether you connect them (+) to (-), which would be series, or (+) to (+) and (-) to (-) which would be parallel.

    Plus to plus to plus etc= parallel wiring, doubling the current (amperage) while keeping the voltage the same

    Plus to minus to plus ect= series wiring doubling the voltage while keeping the current the same.

    At the end of the string, the available power is the same however (not counting wiring loses)
