I bought  4 module type: JC300M-24/Abh               Short circuit 8.69 A
Maximum power 300 w,                                           Maximum current Power 8.20A
Open circuit 44.8 V                                                  Maximum series Fuse rating 20A
Maximum power voltage 36.6 V
Maximum system voltage 1000 VDC . 
those are the specifications on the panels. Does this consider to take 12V or 24v battery bank ?
And what battery bank size and type would give a better performance in a full sun area. Also considering this system gonna have a water
 pump intermitently and a refrigerator on it for my home. Appreciate your opinion.

Okay, since you've started a new thread in off-grid, I'll assume you're off grid. The numbers Bill gave you in your thread in the beginners section are applicable, as are the links to learning about the various components.

A fridge in a hot climate will likely use 2-3kwh/day. You may want to start by buying a "kill-a-watt" meter to get a better idea of your loads.

Is the pump 120v?

Hi, thanks, yes the pump is 120V, that will run temporarily to fill up reservoir which will last often 4 days
