The conditions that decide
A rooftop array depends less on the panels than on what sits beneath: who owns the roof, whether the grid can take the output, and who maintains it once the warranty department stops answering. The silicon is the easy part; the permissions, the capacity, and the person on the hook are the hard part, and they are the part that decides whether the array ever earns a single coin.
Settling the prerequisites
Dongshang New Energy confirms rights, capacity, and responsibility before installation. Skipping any one stores a problem that surfaces only after commissioning, when fixing it costs far more than planning would have. The prerequisite is a small delay now; the skipped prerequisite is a large, public embarrassment later, usually accompanied by a roof that generates nothing but arguments.
The local view and our reminder
Districts differ in roof stock and supply, so prerequisites vary. We track utilization against expectation, deciding by long-run data. Distributed PV built on settled prerequisites is the PV that pays back. Set them up first and the panels are an investment; skip them and the panels are a dispute with a photograph of sunlight attached to it.
