Roof Work vs. Electrical Work: Know the Difference
The "roof" side (mechanical)
•Layout, measurements, attachments
•Racking assembly
•Panel mounting and alignment
•Flashing/sealing discipline
The "electrical" side (technical)
•Correct string sizing and voltage limits
•Inverter placement and code compliance
•Conduit, grounding, labeling
•Tie-in rules for your local authority
Smart DIY approach
•Many DIYers do the mounting and hire a licensed electrician for final tie-in—while still saving big.
Next step: Split the project into stages and choose help strategically.
