The most visible element of a rooftop solar system is, obviously, the panels. And, where I live in New England, I’m seeing more and more of those glossy- or matte-black units topping the homes around me, helping to power more of the local load with green energy while also pushing down their owners’ monthly utility bill.

It’s not unusual that solar photovoltaic (PV) systems would require fuses – after all, these installations can carry substantial electrical loads, so overcurrent protection is critical to their safe operation. What is remarkable, though, are the conditions under which PV panels, their conductors, and their wiring can operate.

Rooftop support systems are an integral part of conduit, piping, and mechanical installations that often go underappreciated. These unsung heroes of the rooftop world provide a stable and secure foundation for equipment, ensuring that everything from HVAC units to solar panels stays in place, regardless of weather conditions or external forces.
