Laboratory Sources & Standards

National Renewable Energy Laboratory (NREL) meteorological irradiance models, solar position algorithms, and system loss derating factor methodology (covering soiling, shading, wiring, and inverter clipping).

National Electrical Code safety factors for conductor ampacity sizing (125% continuous duty multiplier), string voltage temperature corrections, and disconnect requirements for PV arrays.

Battery Chemistry & Monitoring Whitepapers: Peukert exponent values (1.02–1.30), charge efficiency factors (CEF), State of Charge (SoC) voltage-discharge mapping, and inverter idle tare power loss profiles.

Deep-Cycle Technology Guides: Lead-acid depth-of-discharge curves, cycle-life degradation under deep cycling (50% vs 80% DoD), and temperature compensation coefficients (-5 mV/°C/cell).

Alternative Fuels Data Center: Power delivery ratings for Level 1 (120V AC), Level 2 (240V AC J1772 / NACS), and DC Fast Charging (CCS / Supercharger), alongside national average electric utility benchmark rates.

Electric Vehicle Supply Equipment (EVSE) Energy Efficiency: Standby power requirements, onboard charger thermal conversion efficiency, and MPGe energy equivalence (1 gal gasoline ≈ 33.7 kWh).

Residential Energy Consumption Survey (RECS): Baseline household daily consumption figures, heating/cooling split ratios, and electric utility volumetric billing components.

Household Appliance Nameplate Specifications: Typical running wattage, compressor duty cycles, and annual kWh ratings for refrigerators, heat pump dryers, and HVAC systems.
