I am planning on assembling a panel using around 50 or so cells, what I want to do is once I have obtained around 18 volts by connecting the cells in series, I want to increase the current by switching to parallel connections. My question is where to place the cells that are connected in parallel? Do I place them in their own string and then tie them into the other strings? From what I have read it seems that if they were placed behind other cells hooked in series the current flow would be reduced back down to the existing current of that string.

cells in series, increases voltage
cells in parallel, increases current.
I'd suggest making series panels, and then paralleling at the panel level. Get the panels too large, and you can't move them. Of course, you still have all the disavantages of home made panels, doubled.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||
