With a parallel battery connection the capacity will increase, however the battery voltage will remain the same. Batteries connected in parallel must be of the same voltage, i.e. a 12V battery can not be connected in parallel with a 6V battery. It is best to also use batteries of the same capacity when using parallel connections.
In addition, The two parallel connected solar panels will charge the batteries quickly and power up extra load. This parallel wiring configuration is needed in case of 12V system i.e. 12V charge controller and inverter system. For this reason, two or more solar panels as well as batteries (each of 12VDC) are connected in parallel.
