Which roof type has solar panels designed to provide electricity and may be retrofitted or integrated during construction?

• A. Photovoltaic Roof
• B. Photovoltaic (PV) System
• C. Panelized Home
• D. Precast concrete

Answer: (A)

Photovoltaic roofs are built to host solar panels as an integral part of the roof, so the roof itself is designed to generate electricity and can be added during construction or retrofitted later. This distinguishes a photovoltaic roof from a general photovoltaic system, which refers to the electrical equipment and panels themselves rather than the roof design. The other options describe construction methods or materials—panelized home and precast concrete—not a roof type specifically designed for solar energy.
