01 / THE CHALLENGE
A NEW ROOF NEEDS A SMARTER SOLAR PLAN.
When commercial roofs need major work, the photovoltaic system becomes part of the construction schedule. The array must be safely disconnected, equipment removed and handled, and the roof and electrical installation coordinated before solar production can be restored.
At Marin Builders Association, Grid Titans' repowering scope involved decommissioning the existing solar installation and rebuilding a modern rooftop system following roof work. The as-built revision documents a 48-module Hyundai Energy Solutions array totaling 21.12 kW DC, with Enphase IQ8P three-phase microinverters.

NEW PANELS LIFTED TO THE ROOF
A crane delivers new photovoltaic modules to the commercial roof one of the key logistical steps between decommissioning and array reconstruction.
THE REBUILT SOLAR ARRAY
The reconstructed commercial photovoltaic system an updated electrical installation designed to serve the building beyond its roofing improvements.
04 / THE PROJECT
BUILT AROUND
THE SITE.
A real example of the growing commercial solar repowering market where safe decommissioning, electrical infrastructure, equipment selection, new rooftop attachments and coordinated scheduling matter as much as the modules themselves.
DOCUMENTED WORK: Original array decommissioning, roofing coordination, module delivery by crane and commercial PV system reconstruction.
Photographs show the actual removal and reconstruction stages. System ratings are based on the latest project as-built drawings; performance claims are not provided.
