The standard way of mounting crystalline modules to metal roofing is with blocks and clips clamped to standing ribs.
Almost all photovoltaic modules now are equipped with quick-connect wiring that allows installers to simply plug them together.
Modules are wired in a series until they reach a voltage and power level that works best with the power inverter; then, home-run wires are run back to a primary disconnect and the inverter.
The ridge cap is removable for access to the wiring connections.
Although small pieces of metal would not harm the 1/4-inch steel cutting blades, bolts such as the one shown here need to be removed from the material before it is ground.
