I got into DIY solar back in May and have installed a bunch of gear, including solar panels, an Off-grid EG4 12000XP inverter, and batteries. I've done all the installations myself—like setting up the inverter, batteries, and even DIY grounding for the panels in my yard. I've also set up a sub panel powered by the inverter and moved a lot of the breakers there. My setup is powering about 70-100% of my home's daily electricity needs, but I didn't have any inspections or permits done. I verified with an electrician that back feeding isn't possible with what I've got, but everything was DIY and not documented formally.
Now, I'm wondering what counts as "installed" for the solar tax credit that's ending soon. I can provide receipts, photos of my installations, and evidence of my reduced electric bills, along with solar generation data. Is there anything else I should have for my DIY off-grid solar? Do I need any inspections or permits to qualify? I've seen conflicting advice online—some say just take a video while others insist on getting everything inspected and permitted. What's the right approach for those of us completely off-grid?

From what I’ve read, as long as your solar system is operational, you should be all set. You’ve got receipts and proof of the drop in your electricity bill, so that speaks volumes. If they need more proof, someone could literally come and see your system in action. You're golden!
I've tackled similar projects without permits, and I managed just fine with the tax credits. I kept all my receipts and any related documentation. While I've never been audited, I think you'll do great without any issues. Just be ready with all your paperwork, just in case.
Don’t let anyone intimidate you into thinking permits are a must everywhere. Some places don’t require permits or inspections at all! In my area, I only need permits for certain structures but none for electrical work. As long as you can show your system is up and producing power, that’s typically enough!
Exactly! It varies by location, and you seem to have everything in place for your credit.

Totally agree! If it’s running well and you can show proof, that’s what matters. It sounds like you’ve covered your bases.
