- The page says wire runs that exceed its 3% voltage-drop limit are rejected rather than assigned a thinner conductor.
Field notes
The input form accepts monthly kWh or bill text or photos, a US ZIP code, system mode, autonomy, battery chemistry, module wattage, wire-run lengths, and design temperature. The page says bill extraction retains only kWh and that sizing uses state-average peak-sun hours rather than a roof-specific PVWatts run. It also describes a generated PDF and SVG wiring sketch, and says the calculator refuses wire schedules that exceed its 3% voltage-drop limit.
