Solar battery charger question and generator question

We run 2 x 100w solar panels for use at night and park in the shade! We have portable panels which are stowed in the rear locker space and permanent long leads connected direct to our house battery. The leads are coiled up on top of the battery and when stopped we just pull them out and use the quick Mc4 connectors. Yes we have to move the panels sometimes during the day as well to ensure best charge.
