Building-integrated photovoltaics and solar shingles

Treat BIPV as two systems at once: roofing/envelope and electrical generation, including drainage, replacement and interconnection.

VERT / GREEN

Compare roofing function, warranty, performance and repairability before purchase.

JAUNE / YELLOW

A product that generates electricity can also be a critical part of roof weatherproofing.

ROUGE / RED

No substitution or repair that compromises electrical certification, drainage, fire performance or weatherproofing; interconnection by required professionals.

System triage

Product replaces roofing
Verify underlayment, flashing, drainage and future replacement details. No defined spot-repair method
Obtain manufacturer repair procedure and parts availability before selection. Improvised electrical connection
Use certified equipment and required professional; follow grid authorization if connected. Envelope + electrical coordinated
Archive drawings, models, warranties and diagram.

What the professional checks

The roofer/envelope and electrical professional coordinate substrate, flashing, drainage, wiring, certification, fire safety and interconnection.
