In plain language

When a proposal mentions Roof-mounted photovoltaic system, identify the exact equipment, configuration, and included work instead of assuming the label describes the whole system.

What it is not

It is not synonymous with every residential photovoltaic system because residential systems can also use ground or accessory structures.

Decision context

Why it matters

Roof condition, structural capacity, usable area, orientation, shading, access, code requirements, and waterproofing details must be evaluated for the actual property.
