I would wire them 2 in series and 2 string parallel to see the wires loss cause that much lost. I get 60 to 65% name plate in average, you should get 50 amps in average.

that's exactly what I'm averaging ; and if the batteries go below 11.2 volts, ive seen it happen �� I tend to hit 60 amps or roughly 750 watts or so.... Nevertheless I figured an additional panel would get me to "absorp" mode with my load, as I need to stir HIS electrolytes and keep my freezer running 24 hours to make ice for the locals here .

12 volts * 10 amps = 120 watts

120 watts - which is what the kill a watt meter is telling me the freezer is currently using "now" figured the extra panel would hold that weight and the other four would charge the batteries

If your battery below 11.2volts, you are discharge too much. your load is too large for your system. you need to find the exact consumption for the 24 hour period and address the issues from there.

I'm new to RE so I hope you'll have a little lenience towards me, loll; nevertheless why would 5 panels in parallel be bad?....

3 very good reasons, and it is all dollars and cents, a lot of it.

1 As pointed out put 5 in parallel requires you to use expensive combiners and Breakers/fuses, labor, more labor, and higher risk of failure.

2. Put all 5 in Parallel and you have a lower Voltage and the Currents adds. Around 40 amps if I remember your Imp of the panels. If all the panels were in series at 5 times higher voltage is 1/5 the current or 8 Amps. The voltage loss between the panels and controller needs to be less than 2 %. With 8 amps of current, you can run up to 45 feet with #14 AWG. At 40 amps, 40 volts at 40 feet requires a 2/0. You just went from 14 AWG costing 18-cents per foot, to 2/0 costing $2 a foot requiring special tooling to terminate.

there have been consecutive days when I have received bad sun, due to being too cloudy or rain. Which tends to lead to a poor SOC . I try and keep the freezer running 24/hours @ 115 volts HIS killawatt meter gave me i 3.11 kilowatts hours and at 120 volts (inverter had initially been set up
To) I got 3.25. Not much off a difference but since the freezer's label has 115 volts listed, i will stick to 115.

Here's what I just got off the tristar meter .

332.5 Ah
4370 Wh
34.4 vmax solar
1382 W max battery

and i only went into "absorp" mode for 2 minutes

I will just set off and on periods for HIS freezer ; think i'll run it for about 19-20 hours per day then shut it off at 4-5pm and restart at 9. Until I can get my hands on the last and final panel .

you need to get a small generator to charge the batteries in the early morning. 800 to 1000watts quiet generator and an automobile 12 volt 50 amps charger will do the job.
