Installation Process Overview
A reputable installer follows a transparent, step‑by‑step workflow:
1. Site Assessment
Technician evaluates roof orientation, shading, structural integrity, and electrical capacity.
2. System Design
Software modeling (e.g., PVsyst) produces an optimized layout and performance estimate.
3. Permitting
Installer files electrical and building permits with Louisville Metro Planning & Building Services; typical turnaround is 2‑4 weeks.
4. Installation
Certified electricians mount racking, install panels, connect inverters, and integrate with the grid.
5. Inspection & Activation
County inspector verifies code compliance; utility conducts interconnection testing before the system goes live.
