QUESTION 45
A homeowner is weighing the PV module options for a roof-mounted solar array. Which is a correct option to present to the homeowner?

Building-integrated PV shingles will be flush or nearly flush with other shingles, but the electrical energy produced will be less than polycrystalline or monocrystalline modules.

Rapid shutdown requirements within 1 ft of the array boundary.

Polycrystalline modulesare more shade-tolerance than eitheramorphous or monocrystalline modules and allow a larger array to be installed, including in area where shading could be seasonally problematic.

Microinverters can be installed with either polycrystalline or monocrystalline modules, negating the need for rapid shutdown compliance.
