Results

Annual energy
166,440 kWh/yr
Monthly energy
13,870 kWh
Daily energy
456 kWh
Adjusted CUF
19 %

Engineering Formula

  • E_annual = P × CUF × 8760
  • E_daily = E_annual / 365
  • Effective CUF' = CUF × (PR / 0.80)

CUF is the ratio of energy delivered to energy at nameplate over the period. Yield is normalised against 8,760 h/yr per IEC 61724-1.

Step-by-step Calculation

  1. 1.Adjusted CUFCUF × PR/0.8019 %
  2. 2.AnnualP × CUF × 8760166,440 kWh

Design Assumptions

  • • CUF benchmarked to Indian conditions (17–21%).
  • • PR normalised to 0.80 baseline.

Engineering Tips

  • ◆Report both PR and CUF — they answer different questions.
  • ◆Use monthly CUF for O&M KPIs.

Warnings

  • ▲CUF > 24% indicates over-reporting or DC/AC ratio > 1.4.
