So if I wire my 2 solar panels of 18 volts in parallel I will have 7 amps right?
And with 7 amps I will have 126 watts right?Comment

Just to add a note here - 2 panels in series = 126 watts and 2 panels in parallel = 126 watts.
18v x 3.5A = 63w
18 x 7 = 126
36 x 3.5 = 126
Watts in a system alwsys stay the same. You can use higher voltage, and a down converting MPPT charge controller, and save on losses in wires, 7 A needs thicker wire than 3.5A Over several years, the more expensive MPPT controller will pay for itself.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 ||
