# description
Typed schema for generation DER energy resources (solar PV, wind, hydro, biogas, CHP, fuel cell). v1.1: nominalPowerKw → nominalPower (QuantitativeValue); inherits EnergyResourceCommon/v1.1. CIM: GeneratingUnit subtypes (IEC 61970-301/302). SOLAR is a deprecated alias for SOLAR_PV. Optional admin field dcArrayCapacity (QVPower) carries the DC-side nameplate (industry 'kWp') for SOLAR_PV — distinct from AC-side maxExport; IS 16221 / IEC 61727.

# allOf[].properties.type.description
Asset-class discriminator. SOLAR is deprecated; use SOLAR_PV.

# $defs.EnergyResourceGeneratorAttributes.allOf[].properties.nominalPower.description
Nominal (nameplate) power output. unit: W | kW | MW. CIM: GeneratingUnit.nominalP.

# $defs.EnergyResourceGeneratorAttributes.allOf[].properties.efficiency.description
Conversion efficiency as a percentage (0–100). Most relevant for FUEL_CELL and CHP.

# $defs.EnergyResourceGeneratorAttributes.allOf[].properties.dcArrayCapacity.description
DC-side nameplate capacity of a PV array at Standard Test Conditions (industry 'kWp'). Distinct from AC-side maxExport. Relevant for SOLAR_PV. unit: W | kW | MW. IS 16221; IEC 61727.
