About this Gig
Contractors and installers waste weeks stuck in city permitting because of sloppy, generic electrical drawings. You need a bulletproof solar single line diagram (SLD) engineered specifically to pass Authority Having Jurisdiction (AHJ) and utility reviews instantly.
As a professional Solar Engineer, I specialize in the critical electrical side of PV systems. If you already have your roof layout but need the technical electrical schematics to get your permit approved, this gig is for you. I draft precise 1-line and 3-line diagrams compliant with the latest NEC standards.
Your specialized electrical package includes: Detailed Single Line Diagram (SLD) & 3-Line Schematics Precise DC/AC cable sizing & conduit fill calculations String sizing & voltage drop verification Main Panel Upgrade (MPU) & Line-Side Tap drawings Microinverter, String Inverter, & Battery Storage wiring.
Don't let a generic solar schematic delay your installation schedule. Send me your site plan and equipment list, and let's get your permit approved!

FAQ
Q: What is the difference between a single line diagram and a 3-line schematic?
A: An SLD (single line diagram) shows the general electrical path of your solar system. A 3-line schematic details every individual wire, phase, and neutral connection. I provide both based on your AHJ permit requirements to ensure strict code compliance and fast approval.
Q: Do you calculate the DC/AC cable sizing for my specific equipment?
A: Yes. Every solar SLD includes exact DC/AC cable sizing, conduit fill, and voltage drop calculations matched perfectly to your solar panel and inverter datasheets. This prevents voltage issues and guarantees your electrical schematics pass city inspection on the first try.
