Field notes

The proposed workflow moves from physical layout to electrical validation: panel orientation and string grouping feed voltage and current totals, while temperature assumptions alter the design values before hardware selection. The page says its offline library covers more than 40 residential panel SKUs and 15 string or hybrid inverters. It also describes side-by-side comparison of two named plans and a printable output containing the string map, wire schedule, equipment list, and derating assumptions.
