Thanks wiki
i understand the first part of your reply...
just typing here in a little more clarifications (defiantly this will help the other readers, as i learned many many thing from PW)
""" U can add up to 4 panels (22.7v(100w)5.66Amp) in series for 12 volt battery system
and for 24v battery system u can add up to 6 panels (22.7v(100w)5.66Amp) """
12 volts battery system = 22.7voc of panels x 4-Qty of Panels in series = 90.8 volts max (that is under the 150VDC of my charge controller and also approx around the limit of 12V-390W because 4-Panels means 400Watts.
24 volts battery system = 22.7voc of panels x 6-Qty of Panels in series = 136.2 volts max (that is under the 150VDC of my charge controller and also approx around the limit of 24V-780W because 6-Panels means 600Watts.
and the second part of your reply is not clear to me...
""" the DC output current U will get with 12 volt battery system is approx 10Amp to 12Amp
and with 24 volt battery system it will be approx 5Amp to 6.5Amp """
as per my knowledge when i am going to connect all in a series...
22.7voc of panels x 4-Qty of Panels in series = 90.8 volts max
but Amps will be same as of my single panel i.e. 5.66Amp
now how to calculate the Amps for a 12Volts system and a 24Volts system??

i have an other scenario too (already installed and working with me, hereunder are the results of that, it may help someone new interested in a total 12-Volts DC system)
==
1 Dry Battery 12Volts 150Ah (Narada-Dry battery just installed few weeks ago, since previous year it was working with my Old Wet-Batteries of UPS "2 batteries of AGS-GR85 connected as parallel"")
2 mono panels of 100watts each (Output Peak Power: 100Watts - Open Circute Voltage: Voc:22.7V - Short Circute Current: Isc:5.66A - No. of Cells : 36 - Power Tolerance: 0/+3% - Max. Power Voltage: Vmp:18.9V - Max. Power Current: Imp:5.29A - All data standard Test Condition (STC): - AM= 1.5 - E=1000W/m2 - Tc=25C )
30Amp PWM Charge controller with LCD display (it may also work with a 20Amps controller but i prefer this controller cause it is with a LCD display to check my 12volts consumption and production as well as the volts of battery and other good features too, this charge controller helps me to check on daily-basis... if my consumption increased and battery looks going down, i may charge it with external 12-volts charger or control my next day consumption so the battery may full again)
Cable from Panels to Charge controller is 6-mm Mash Cable (pure copper) around 75 feets
Load... i use mostly on this system :
1 DC ceiling fan 12volts - 25-Watts (as per manual of it) but mostly it consumed around 1.8-2.0Amps per hour (displayed on my charge controller) the air flow of this DC-Fan at full speed is about 60-65% compared to my old Royal-Fan-AC.
2 lights 12volts - 10-Watts each - LED/SMD type and each light consumes around 1Amp per hour and light is almost equal to 18watts energy saver.
the bottom line of my 12volts DC system is 2 panels of 100Watts each (total 200watts) with a 12volt battery of 150ah with 6-mm cable of 75-feets and a charge controller of 30Amps with LCD display...
in a day my 200Watts panels generate around 40-45Amps
is it ok or not experts may confirm it...
but when we looks at WAPDA...
This 1 Room DC-Setup is going well... i also observes Battery life/works more in this DC setup even i used old batteries with it.
Thanks for reading this longggggg reply.
