The romex 10 2 will be inside garage only.
Using romex to connect solar panels.
2 romex into the attic the romex probable needs to be clamped so hopefully i can position the solardeck in a way that a short run of plastic conduit lands near a diagonal roof member to mount a junction box which will only be used for the clamp no actual electrical junction.
Some circuits would be dc and some ac via an inverter.
Connecting solar panels in series.
On the other hand if our two solar panels have both different wattage and different voltage then parallel connection is not possible since the panel with the lowest voltage would behave like a load and would begin to absorb current instead of producing it with the.
Solar wire types also known as solar panel wire and pv wire refers to the type of wires used to connect your solar panels with the rest of your photovoltaic system.
My question is if there will be problem with me using romex 10 2 to connect inverter to ac disconnect that sits on the outside wall of the garage.
Romex 10 2 is good for 30a.
But now i d rather not.
Solid wire passes electricity at a capacity 1 size greater than stranded wire.
Stringing solar panels in series involves connecting each panel to the next in a line as illustrated in the left side of the diagram above.
Connecting solar panels in series.
So if you connect two solar panels with a rated voltage of 40 volts and a rated amperage of 5 amps in series the voltage of the series would be 80 volts while the amperage would remain at 5 amps.
Romex cable comes with multiple conductors encased in a second insulated covering.
Why i chose 10 gauge romex wiring.
My reason for choosing to go with 24v is that i d like to use some of the circuits already in place connected with 12 awg romex wire.
Just like a typical battery you may be familiar with solar panels have positive and negative terminals.
That means the 10 gauge wire works as if i had used 8 gauge automotive wire.
If we have two solar panels with the same voltage but different wattage there is no problem.
Romex is available at home depot and is much cheaper than 10 gauge automotive wire.
For my installation of rv solar panels 10 gauge household romex wiring was chosen for a few reasons.
They can be wired in parallel.
How to choose and use the right wires with your solar system.
More protection is always better.
Until i put in a whole house solar system i m setting up a small system 400 ah 24v batteries 600w solar panels.
Choosing the right wire for your solar energy system is critical to it s functioning properly and remaining undamaged.
