Simulation 05 — Solar Rooftop Quick-Check

How much solar
fits your roof?

A commercial rooftop solar project starts with three answers: how many kilowatts fit, how much weight the array adds, and whether the structure is likely to carry it. This tool estimates all three from usable roof area, structure type and building era.

◆ Screening estimate: ~62% roof utilization after setbacks/walkways, 550 W modules, Gulf Coast production factor. Real capacity depends on framing, existing dead load, drainage and wind uplift zone — verified in a 3–5 day structural analysis before racking is ordered.

In short

  • Array capacity is estimated from usable roof area, module count and orientation.
  • Added dead load in pounds per square foot determines whether a structural upgrade is likely.
  • Structural risk rises with building era; older roof structures carry less reserve capacity for added load.
  • Aria engineers rooftop and ground-mount photovoltaic systems with structural review and interconnection support.
