A collection of solar, battery, wiring, and generator sizing calculators supported by plain-English engineering notes.

Landing page captured for the 2026-08-27 issue.

Field notes

ArrayBudget divides its material into several calculation libraries rather than presenting a single generic solar estimator. The homepage lists 336 battery-bank cases, 768 DC wire-sizing cases, and 3,712 backup-generator cases, with examples spanning voltage, autonomy, cable distance, motor horsepower, and fuel type. Short explanatory pieces address practical interpretation, including why roof coverage exceeds panel area and why annual solar averages can conceal the seasonal conditions that matter for system sizing.
