MODEL: Energy is an uncalibrated planning estimate from ERA5 and a 5 m horizon model. Field accuracy has not been established against an independently verified matching installation and retained calibration inputs; private browser uploads are not canonical source evidence.
SURFACE: DSM catalog metadata describes acquisition campaigns in 2017–2020; exact cell dates are unknown. The frozen 5 m surface may differ from 2024/2025 and omits small objects, seasonal foliage and electrical mismatch.
SCOPE: The retained canonical source context is a 2 × 2 km Tartu pilot. Another selected Estonian area loads its own bounded source context and remains exploratory; missing context is not extrapolated from Tartu.
MARKET: Energy value uses explicit consumption, inverter and net-export limits; optional storage is a separate historical dispatch comparison. Figures exclude taxes, unentered grid charges, dynamic operator curtailment and financing. The default import adder is zero, and 2025 quarter-hour prices are averaged hourly.
LICENSE: Elering price-data reuse licensing was not verified in the public API documentation; source attribution and the unresolved status are retained.
ML: Aerial PV detection and installation-level government reconciliation are not evaluated; available government data are municipality aggregates.
CONSUMPTION: The published 10 kWh day / 4 kWh night household demand is an estimate, not a measured household profile. Partial CSV imports do not establish full-year demand or savings.
STORAGE: Optional battery dispatch uses historical price knowledge, finite state resolution and explicit losses/limits; storage is disabled in the canonical baseline. The model excludes battery investment and does not guarantee trading returns.
