THHN and Welding Cable for Wiring Solar Array Projects

Written by Admin | Feb 21, 2013 6:00:00 AM


We really enjoy these pics that were sent over from our friend Michael in Southern California. Michael did a massive solar array installation on his home & decided to buy #2 THHN Copper Building Wire along with 4/0 welding cable for his battery cables.

He also created an entire blog about the process of buying & installing all parts for his solar project. Michael gave us a great recommendation which was fun to see and greatly appreciated !

Here is what Michael had to say:

"The wire run from the panels to the charge controllers is over 180 feet.  Sourcing the wire for this run took some time.  I initially was going to run 4 gauge wire.  The plans call for 4 gauge wire.  When I went back and rechecked my calculations, I realized the voltage drop would be almost 5%.  Not acceptable.  3 gauge wire would do it but I decided that I wasn’t going to take any chances and ordered 2 gauge wire.  When it comes to wire, I have found there is only one source,   Wire And Cable Your Way.  They have the best service, the best prices and they ship for free on orders over $1000 and they are FAST!  When I realized I needed to run a thicker wire. I called up Seth and he got on it.  He also called back to make sure I was taken care of."

We recommend you checking out his blog if you are interested in learning about the process of installing a solar panel for your home. It's very informative!

It was fun doing business with you, Michael!

BTW - if you are planning any electrical installation at home, we highly recommend you consult with a local electrician first.  They can advise you on current state electrical codes and which type of cables are suitable for the application.

Thanks for stopping by.
