Yeah, I know.  Trying to have a discussion with George is like mud
wrestling with a pig.

You are the one that suggested that such a SS would be a good thing.

The numbers you provided add up to 11 panels.

Can't do it can you

180 Ah is true and correct minimum capacity for the job.

The 45.2C was your number. The results I have shown are correct.

 From the standard test temp of 25C my

STC is the standard. The numbers given are what you get when you raist
the OCT to 45C.

Care to prove it wrong. But no, you can't. Sill of me to ask.

If you are just comparing the output of the panel with a cell temperature
of 25C vs a cell temperature of 45C, then you are correct in your
assumption that the output will be less.

But you still remain unable to provide any real world materials for your

And we're still waiting to hear where you got your 14Volt specification

Since you falsely claim that 11 panels was my recommendation, let's be
clear that I was rounding up YOUR conclusion that 10.3 panels would be
enough.  So I'll withdraw my 11 panel interpretation of your 10.3 panel
conclusion and wait for you to provide a panel that can be purchased at the
10.3 panel size.

Obviously you don't recall that my only recommendation was for 10 panels of
the type the OP had available, whereas *your* recommendations have been:

GG: (1st try) 154 panels

GG: (2nd try)  17- 50W Panels

GG: (3rd try)  (C5 / C12) = 10.3

You can also tell us who makes a battery that meets *your* specifications

B2     Maximum allowable depth of discharge = 70%
B13     Capacity of battery bank at 100 hr rate (B12 x B10) = 180
C4     Battery efficiency = 90%

and will also work in the proposed application.  So far you haven't even
come close.

No, I said 11 panels. 10.3 rounded up

Thats right and I said 10.3 Rounded up to 11

Almost all deep cycle batteries. Most will in fact handle as much as
80% maximum DOD. Maximum DOD is a fairly rare occurrence in a properly
designed system.

180 is the minimum battery capacity required. I never recommended a
battery. You recommended T105s.

Hey, it works.

I never recommended a battery for the application. You recommended
