bought from Amazon for $201.59 plus a bit less than $17 sales tax.Ebay vendors with good reputation have similar or slightly higher prices, with roughly similar dimensions. The maximum width (front to back on the closed shell) iis only about 31" on my 2619. This panel, only 26.38 inches wide, 7 fits easily, with the "width" front to back, the "length" running curb side to street side with tons of extra room.
I was unable to find a longer panel with more cells per row (and higher operating voltage, without exceeding my width limits.
That panel is now priced at $222 pre-tax:
