Rooftop Solar Installation
Residential rooftop photovoltaic panel installation — from system design to interconnection.
Rooftop solar is the most common residential install: photovoltaic panels mounted to the roof, an inverter (string or microinverter), a production meter, and a utility interconnection. A reputable installer handles structural review, permitting, AHJ inspections, and utility paperwork — not just the panels. Look for NABCEP-certified PV Installation Professionals and ask whether the panel and inverter warranties are 25-year linear (panel) and 10–25-year (inverter).
