Partial Solar PV sizing, battery bank sizing, and payback math are formula-based and vibe-codeable. However, engineering-grade results need irradiance data, local code compliance, and validated loss models, which require domain expertise.
What it would actually take: The calculator would combine formulas for array sizing, string voltage limits, battery bank capacity, and cash-flow modeling with irradiance from NREL's PVWatts API. The hard part is validating against NEC code requirements, inverter and battery specifications, and local utility tariffs, and matching the output to what installers and engineers accept. A licensed PV engineer should review the models and assumptions.
