Technical Sources

Primary documentation, with a clear boundary between the reference and our simplified model.

Reviewed 2026-11-01. A linked source explains the relevant principle; it does not endorse or certify these calculators.

U.S. EIA · Measuring electricity ↗

Watts measure power; watt-hours measure energy. The arithmetic on these tools is derived from those units.

Victron Energy · Battery monitor settings ↗

Charge efficiency and rate-dependent capacity. Our simple runtime model does not implement Peukert compensation.

NREL SAM / PVWatts · System design ↗

Context for solar losses, array ratings and variability. Our peak-sun-hour estimate is a simplified energy balance, not the PVWatts simulation.

Fluke · Power factor and real power ↗

Power factor relates real power in watts to apparent power in VA. We use RMS quantities for single-phase AC.
