1. Submit project details
Share company, contact, project address, and equipment info through our design request form.
2. Design & site review
Our team reviews site conditions and equipment to produce a PV layout and single-line diagram.
3. Engineering & permit prep
Structural/electrical calculations and the full permit package are prepared for your AHJ.
4. Delivery & support
You receive the permit-ready package, with support through the review and approval process.
Design solutions sized to the project
Residential rooftop systems and commercial arrays have different structural, electrical, and permitting considerations. We scope each project accordingly rather than applying a single template.
Residential Solar Design
Rooftop PV layouts, string sizing, and permit sets for single-family and multi-family residential systems. See residential design details.
Commercial Solar Design
Larger arrays, more complex electrical distribution, and coordination with commercial AHJ requirements. See commercial design details.
What's in a permit package?
A typical solar permit package includes the site plan, PV layout, single-line electrical diagram, structural attachment details, equipment specification sheets, and required labels/placards — assembled to match your AHJ's checklist.

Common questions from installers & EPCs
Solar Journey works behind the scenes with solar installers, EPC companies, and contractors — we are a design and permitting partner, not a competing installer. Your company and your client relationship stay front and center.
At minimum: the project address, a recent utility bill, and basic equipment selections (module and inverter). Photos of the main service panel and roof/mounting area speed up review. The design request form walks through everything we use.
Yes. Our design and permitting workflows cover residential rooftop systems as well as small and mid-size commercial arrays, with scope adjusted to the site and equipment involved.
Yes — see Structural & Electrical Engineering for how stamped calculation packages are prepared and what jurisdictions typically require them.
Requirements differ by Authority Having Jurisdiction (AHJ) and by which edition of the National Electrical Code and International Residential/Building Code your jurisdiction has adopted. Our permitting team tracks these requirements per jurisdiction rather than applying a one-size-fits-all package.
