What are the challenges facing enterprises in building photovoltaic?

The exact extract asks for the challenges enterprises face when building photovoltaic systems. The correct answer is A, B, D, E. Distributed power plants being unable to be managed in a unified manner is a real enterprise challenge because C & I customers often have multiple rooftops, sites, branches, or plants that require centralized monitoring and O & M. Not being able to fully use roof area is also a challenge because rooftop structures, shadows, orientations, fire lanes, and string limitations can reduce deployable PV capacity. Poor development quality and many faults reflect design, construction, commissioning, and O & M risks in distributed PV projects. Hidden safety hazards are also a major issue because DC arcs, insulation faults, rooftop high voltage, and ESS risks can affect personnel and assets. Option C is not selected because the issue is not that high-efficiency modules are unavailable; the bigger problems are management, roof utilization, quality, faults, and safety.
