I have 6 of the HI=MO X6 LONGI LR5=54HTB-430M
The specs are:
Electrical Characteristics (at Standard Test Conditions - STC):

• Peak Power Voltage (Vmp): 33.16 V
• Peak Power Current (Imp): 12.97 A
• Open Circuit Voltage (Voc): 39.43 V
• Short Circuit Current (Isc): 14.00 A
• 
  
• So the total voltage would be 33.16 * 6 = 198.96v
• And the solar panels would be connected all in series, and the amp would stay at 12.97 amps
• Did I do the math correctly, and what type of solar wire should I use for a 65-foot length from my Eg4 6000xp to my 6 solar panels?
• Take away 4 solar panels from the left, leave the 6 solar panels, 3 on top and 3 on the bottom. This was the only wiring diagram I could find, but this is how I would do it. What do you guys think?

Picture is 5s2p. You describe 6s1p, so just the top or bottom.

Make sure temp adjusted Voc is safe for your inverter.

Standard 10awg wire is good.

No combining cables needed.

Personally I'd go bigger wire size. The difference in cost is minimal.

You might expand the system later.

As suggested - 10awg 6mm.

You still need to correct max voltage for temperature. Table 690.7A. That's what you label it with.

The wire has to have an ampacity sufficient to handle the short circuit current. So even 14AWG is good for that.

You can use this website to figure out what size wire you need for voltage drop, https://ressupply.com/learning-center/wire-sizing-chart-and-formula, unless you want to use ohms law.

Hope this helps.

Home Depot has some 10awg 100 ft Thhn 30 amps for $79.99. You think this wire would be good?

No.

That's not pv wire.

Look for pv cable.

It'll be red and black.

Don't type thhn when searching for it. Thhn would be used for ground wire in your scenario.

Personally I'd just buy pre made cable at your desired lengths. Buy it from a reputable seller though, don't buy cheap junk.

The cheapest will be from a Solar distributor on eBay or Ali.

It will be much cheaper there due to not having store overheads like rent and paying staff.

The worst place you could buy it from would be a company that installs solar. They'll try and charge you 3-4 times the distributor price.

If it's in conduit it's fine. If the conduit is in or on a building it has to be EMT (EMT needs to be bonded) or rigid. You also need at least a 10AWG green wire to go in the conduit for bonding to ground, I've heard different sizes up to 6. I would consider larger than 10. All the panels should be connected together with a copper wire and ground clamps and they should connect to that green wire.

You should do a drawing and meet with a professional electrician or electrical engineer if you aren't versed in this. Get a permit as well.
