Yes ! Size ( I mean wattage, Voc and Current) and Quantity of panels also matters for Charing the batteries But Charge controller has also major role for charging of batteries, MPPT AND PWM charge controller which one is best ? Answer is MPPT as it extract maximum power and provides better efficiency  as compared to PWM

Lets assume that we have 150watt solar panels having Voc is 17 Volts and We are going to charge 24 V battery  in this case we use 150 Watts 2 Panels in series to make 34 volts to meet charging voltage requirement,  now its 34 v how we charge 24 battery so we will chose a MPPT Or PWM Charger with Input voltage Range Vin dc or Voc PV array should be greater than 34 Volts. This charge controller will charge 24v battery  

`150 Watt 2 Panels in series 17voc each =34 volts Current will remain same  in series we call it PV array 1  ( now if you want to increase charging current) than you have to make an other array of Panels and connect them in parallel to get more current.

So conclusion is,

always choose panel size according to batteries voltage.

always choose inverter and charger as per solar Panels Voc, current and battery charging current

always choose solar panel quantity as per battery charging current requirement 

Hope it clear your question.
