I'm Here, But I'm Not All There
My present array was designed using the Midnite Solar sizing tool and pretty much maxed out 1 Classic 150 scc. Midnite Solar has assured me there is no problem over paneling the Classic 150 even doubling my present size, the excess power will just be wasted. Overpaneling will help (I believe quite a bit) in mostly cloudy days etc.
I am doubling the size of my roof top array. Presently 3s3p 285w at 2565w array.
Roof faces due south in FL at latitude 29°. Roof pitch is 22°. All panels are mounted flat on that roof, so they are pitched 22° south. This array on a good cloudless day in Oct can produce up to a max of 12 kWh per day. Average is probably 5-9 kWh per day.
Was going to add 9 more panels in a 3s3p arrangement right beside the existing array, again flat on the roof at 22° south. And bring all 18 panels 3s6p into the one Classic 150.
But I am now wondering before I install the new 9 ... If I was to mount all 9 of the new panels on that same roof at 22° south, BUT I also pitched/tilted each new series string 8° West, then those new 9 panels would catch the sun a little more as it was Going down in the west. I would space them so no shading from the sting to the west of each column. Each series string would be 40" wide x 198" long (the 198" is from roof peak to eve).
Would I get much benefit in the afternoon from having half the array tilted 8° West while still tilted 22° south like the first 9 panels?
What issues would this create if any with a single Midnite Solar Classic 150 scc?
