Solar panels and solar shingles: how they differ
Panels sit on a mounting structure. Shingles and tiles are part of the roof.

Panels on a mounting structure
DOE says PV arrays "must be mounted on a stable, durable structure that can support the array and withstand wind, rain, hail, and corrosion over decades."
Shingles and tiles in the roof
DOE says modules can also be "integrated directly into building materials like roofing," and calls these systems building-integrated PV, or BIPV.
Questions for any bid
For either type, the FTC says bids should have in writing "its size and how much power it's expected to deliver," "the full cost of installation, including any building or electrical permit fees," and "what warranties apply to the equipment."
What we do not say
We do not say one type is better, and we do not compare looks, costs, or output. We do not give costs, savings, payback, or home value figures.
