Send one single-line diagram, a photo of the panel label and the inverter data sheet. Within 2 business days you get a short written review: the busbar arithmetic for your panel, the 705.12 busbar label, and a check of the working space in front of the panel, with the items a plan reviewer would likely flag.

More than 25 years in electrical and critical-power design and standards: PV and battery storage, generator plants, microgrids, dual-utility feeds, power distribution, from the single-line diagram through construction and commissioning, with a BSEE from Penn State. The methods are written up in the field guide Solar on the Busbar and explained section by section on the YouTube channel What the Code Actually Says.
One string inverter, or one microinverter system on a single backfed breaker. One load-side connection, one panel.
Busbar: the 705.12(B) method that fits the panel, including the 120% rule and where the breaker must sit.
Label: the 705.12 busbar label's wording and location. Other PV markings are not checked.
Working space: depth, width and height in front of the panel, 110.26.
Battery storage, more than one inverter system or source, subpanels and multi-panel systems, supply-side connections (705.11), three-phase commercial gear, conductor and overcurrent sizing on the PV side, fault current, and utility requirements. These are larger jobs than a $195 review and are not offered here.

Is this an engineering service or a stamped design? No. It is an informational code review of the documents you send. It is not signed or sealed, it is not a design, and it is not an inspection.
Does it replace the permit review? No. It points out code problems in your documents before the plan reviewer sees them. The AHJ has the final word.
Which Code edition? The 2023 NEC only. If your jurisdiction enforces another edition, the review says so on its first page.
Refunds: a full refund if you cancel before sending your documents. Once the review is delivered the fee is non-refundable. If a rush review isn't delivered by the next business day, the rush fee is refunded. If your documents show a system outside this scope, we tell you within one business day and refund the fee in full.
The review is based only on the documents provided and is offered for information. It is not engineering services, a design, an inspection, an engineering seal or legal advice. You remain responsible for your design and its compliance. Liability for any review is limited to the fee paid for it. By ordering, you accept these terms.
