FAQ

Quick answers

Do I need CAD or drafting experience?

No. The roof plan, one-line and sheets are drawn for you. If you can read a plan set you can make one.

Is the set NEC compliant?

Every set is checked against the NEC edition your jurisdiction has adopted, with the article cited. The contractor of record still reviews and submits.

What does the Solar Agent do on its own?

It keeps every open job moving: notes, tasks, follow-ups, and anything stalled or past due. Anything that reaches a customer or moves a job waits for your approval.
