How to Increase the Watts in my Solar Panel?

[rdlrn19]

Hi, My name

[Jarod]

So my question is: What I need to do if I want to have an output of 126 watts but with 12 volts? Should I connect my 2 panels in series or in parallel?

Thanks !

In parallel, and the current will be doubled.

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?

yep

thank you so much I clarify my question

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.
