Federal Tax Credit and Solar PV question: Any items that don't qualify?

I am adding four Mission Solar 345 W panels and four Enphase IQ7+ to my existing array to get closer to 100% consumption coverage. It will be a fun weekend project, and I am looking forward to it!

Since this will be DIY, I wonder if all the supplies I am using will qualify for the federal tax credit. All supplies and tools are new equipment, and I have proper invoices for everything.

Here are specific questions I have regarding the following expenses:
1 .Does sales tax paid count towards the federal credit?
2. Do shipping charges count?
3. panels, inverters, racking and mounting hardware (They fully count, I would assume.)
4. crimp tool for making field connections (This is a tool, thus not part of the installation. But since it is needed, does it count?)
5. backfeed breaker in main panel (Not part of the solar array per se, but does it count as well?)


Thank you so much for your help!

Only thing I will tell you is that if this is for a FIfth wheel or travel trailer, it will not count. FOr RVs, must be powered by an engine like a class A.

I’d also recommend you plan to what people tell you, but if you can get a tax preparer to sign it off, it’s official, meaning that he would have to fight it if bad advice is given. I’ve probably put some incorrect terms in that last sentence also, but the meaning is, after myself losing money on bad free advice, best to get paid advice from someone official and willing to put their signature to it.

JPM, general advice is not of much use to me, but I totally get your point. As I said, I found relevant docs that answer my questions. It’s all good. I am afraid that my ego is as big as my solar array. Nameplate rating is only 4.5kW. Room to grow, I suppose.
Seriously, I am here to read and learn from those with more experience. No snarkiness implied.

There are no prohibitions in this type of loan if you know all the details that would help resolve the issue peacefully. For me, the loan was salvation, but it led to some risks. To prevent an even bigger catastrophe, I had to ignore some factors that led to problems in the financial component. I was lucky to find https://www.remonttilainaa.com and be successful in paying my credit. That is why there are no other ways for me to advise you on something more effective.

Hey man, can you share more information regarding the solar panels you purchased? They are virtually non-existent in my country (people don't care), so finding someone knowledgeable is a pretty tricky task. Still, I've had this dream of ordering some for a long time! Moreover, what about the taxation expenses? In the end, is purchasing it cost-effective? I've recently had a very unpleasant experience with tax payment because of my ignorance, so now I'm spending a lot of time trying to fix the gap. I've just learned that you can create pay stub free of charge online, so there's a long way to go! I'll keep an eye on this thread, cheers.
