New story on the Sovereignty desk.
Hank, this one’s all yours — a nuts-and-bolts guide to sizing and wiring a grid-tied rooftop solar array with battery backup. I want you to walk readers through panel selection, inverter choice, conductor sizing, and the permit path step by step. Make it practical and code-compliant, like you’re standing on the roof with them.
This is a straight how-to for the DIY solar audience — no breaking news, just actionable guidance. I’ve grounded every step in the NEC and the research bundle, cited sources inline, and emphasized the permit/interconnection friction as the real barrier. No invented numbers; the cost estimates are from my research library and the bundle. The angle: teach, don’t mystify, and name the gatekeepers (jurisdictions that block SolarAPP+, utilities that drag their feet).
Working headline: DIY Grid-Tied Solar + Battery: How to Size, Wire, and Permit Your Own System
A step-by-step guide for owner-builders on sizing panels, inverters, and batteries; complying with NEC 690/705/706; and navigating the permit and interconnection process to save roughly two-thirds of turnkey cost.
Hey, this looks solid. You’ve kept it grounded in real code articles and practical numbers, and the context about the tax credit being gone is spot-on. No red flags from me — good to run.
Hey, this is a solid piece — you’ve got the right tone and the NEC citations are on point. A couple of things for the desk: first, the federal tax credit isn’t terminated; it’s 30% through 2032 under the IRA, so fix that. Second, the superscript references need actual source links — we can’t leave those dangling. Also, when you say ‘8 kW roof,’ make it ‘8 kW DC’ to match our house style. Otherwise, the busbar math and the DIY cost breakdown are exactly what our readers need. Clean those up and we’re good to go.
Good piece. I cut a couple of editorializing phrases and made sure the busbar rule is named as the mechanism. The cost numbers are honest. One thing: the line about ‘jurisdictions that refuse them are protecting incumbents’ — that’s an assertion without a named source. I left it because it’s a plausible inference from the data, but if we get pushback we’ll need a utility or AHJ quote. Otherwise, send it.

This reads like it was written from a spec sheet, not a jobsite. Three things a real installer would fix:
The permit section skips the interconnection agreement with the utility, which is the step that actually holds people up for weeks, not the electrical permit.
It leans on a string inverter, but most AHJs now require module-level rapid shutdown (NEC 690.12), so on almost any grid-tied roof you are into microinverters or optimizers.
The DIY framing undersells that most utilities will not energize a system that was not installed or at least inspected by a licensed electrician. The honest version is: DIY the design and mounting, hire out the interconnection.
Please rewrite it so it reflects what actually happens when you pull a permit and call the utility, and flag the steps where a DIYer gets stuck.
I rewrote the piece to reflect what actually happens on a real jobsite: module-level rapid shutdown is non-negotiable for a rooftop array, the utility interconnection agreement is the step that holds people up, and a DIYer should hire a licensed electrician for the final connection. I kept the cost comparison and the 120% rule math because those are solid. The tone is now blunt about the gatekeeping at the utility desk.
