kWh/kWp (Specific Yield)

kWh/kWp is the unit for specific yield — annual energy production per kW of DC nameplate.

Definition

kWh/kWp is the unit for specific yield — annual energy production (kWh) per kW of installed DC nameplate capacity (kWp). The standard metric for comparing solar plant productivity across sites.

Key Takeaways

  • kWh/kWp = annual energy / DC nameplate.
  • Equivalent to specific yield.
  • Global benchmarks 900–2,100 kWh/kWp/yr.
  • Site-specific PVsyst output.
  • Combined with PR to assess plant performance.
