My new construction home DIY solar build thread (EG4 18Kpv) Texas 🇺🇲

So why is PVC okay outside the building, say on the roof, if that is the reason? Fire there is okay somehow?
It depends on the jurisdiction. Mine won't allow PVC on the roof anymore... EMT minimum required. The PVC gets brittle with enough UV exposure here.
 
I am mid build new construction. And have found room in the budget for an 18k. What’s the line diagram look like? Is it meter, whole house disconnect, eg4, panel? Is the disconnect not required?
 
3hp well pump? Is that correct?
Id consider going with a three phase unit and drive it with a vfd. It will be more reliable and you can soft start it with a vfd. Single phase submersible pumps are ok, three phase much better.

Disconnect is required for most utilities/jurisdictions.
 
I see all of your inverter knockouts connected to the gutter. Isn't the PV power supposed to feed directly to the inverter in metal conduit and NOT in the gutter with the AC wires?
 
I had good luck with IronRidge, the HUG fasteners went well on my painted shingle roof.
Thanks, I'll take a look at IronRidge. Is there a good online distributor for their products? They seem to only go through dealers, not direct.
 
I am about to mount my 18Kpv on an inside wall. In looking at your picture it looks like something other that sheetrock behind your 18Kpv. Could that be cement board? Wasn't sure if the inverter could be mounted with sheetrock behind it. Lee

I have mine mounted on cement board….

Yes, non-combustible cement board.

Sheetrock isn't nearly string enough to hang the 18Kpv on, you either need to hit the studs for the bracket or better yet, use cement board.

Double layer of type-x 5/8" drywall is likely better than cement board. It has an actual fire rating where cement board doesn't. You need backing or mount to studs either way. Personally I would use Unistrut to offset it from the wall a little but that is me.
 
Isn't the PV power supposed to feed directly to the inverter in metal conduit and NOT in the gutter with the AC wires?
As long as the wires are rated for the highest voltage carried in the conduit, it is OK. THHN and Romex are rated for 600V.
Do you think I should have more than my 1/2 " sheetrock on the ceiling directly above it?
If this is a garage, the sheetrock should already be 5/8th. But if in the house don't worry about it, the fire hazard is already inside.
 
Thanks, double 5/8. Do you think I should have more than my 1/2 " sheetrock on the ceiling directly above it?
Ideally you use Type-x everywhere in a room with higher fire risk. How much you want to replace just gets down to practicality. An extra sheet on the ceiling seems like a good idea.
 
It probably won't matter as I am in the country seven miles from a town that has only a volunteer fire department. Yesterday my neighbor about 3/4 mile from me had a fire in his detached garage catch fire and along with a shed close by burned to the ground. The six fire trucks from town and two neighboring towns responded but first didn't arrive until most everything was engulfed in flames which was about 20 minutes from when we first saw smoke. The buildings and several trees all gone. Lockley the 1920 three bedroom house was saved. My system is in my 26 X 40 heated shop about 150 feet from the house. I think if my wiring size and routing are good there should not be much risk of fire. Thanks for everyone's input on wall mounting and sheeting.
 
I got mine as part of a kit from GoGreenSolar.com
I checked with them and they won't sell me racking only. I guess they only do kits.
Where else could I buy IronRidge racking? Seems like they don't sell direct, only to dealers/installers.

Hi Austin,
NAZ solar online. Just got a pallet of panels from them, pretty quickly too. They have iron-ridge on their website.

Greentech renewables, but that is more of a quote/PO operation. There are places that have it. I bought some from Greentech, and they sourced the plastic ends, wire clips, all that.

Another place I use quite a bit is the Practical Preppers website. Great crew there. Knowledgeable.

Good luck with your project!

I love Greentech. Very competitive prices and the staff at my local one is top notch.
 
It's been a few months since I've posted any updates so I thought I'd share that my panels arrived today!

I went with a pallet of 30 Canadian Solar 395W Mono-Crystalline Solar Panels.

:unsure: still trying to decide on which mounting system to use on my roof. Any suggestions?

What kind of finish on the roof? I went with K2 systems and I'm really happy with results. I have a metal roof and their mounting system attached directly to the peaks. I found a distributor that sold them and gave them the BOM from the K2 site. Shipping wasn't pretty but had the stuff in couple weeks.
 
Thanks. I actually plan on running two 18Kpv's, but starting with one to see how it goes.
hello.. im new to the group and new to the industry. we just finished our house and now im going back to consider solar .. I also have two 200 amp panels separated along the length of the house (east garage and west garage).. 2 questions. Why the 18K vs the 6000XP .. are you doing net metering or going for features / warranty ? and, are you planning to install one inverter by each panel or are your panels located in the same room/area ?
