Simulation Results & Analysis: Simulation Engine

The simulator runs a 12-month energy model (monthly resolution approach):

POA irradiance (H_POA from transposition)
Effective irradiance: apply IAM correction, soiling factor
Cell temperature: NOCT model or Uc+Uv model (per Uc, Uv, wind speed)
E_array: Pnom × H_POA_eff × temperature correction × DC loss chain × bifacial gain
Clipping: apply ILR-based clipping loss
E_AC: E_array × η_inverter × (1 − AC_wiring_loss)
P50/P75/P90/P95: apply Gaussian IAV uncertainty

POA Irradiance is the actual sunlight hitting a solar panel at its specific tilt and orientation. TMY (Typical Meteorological Year) is a synthetic dataset of hourly weather values meant to represent an "average" year over a long historical period To get the most accurate performance estimate for a PV plant, system designers take the raw horizontal GHI data from a TMY file and mathematically transpose it into POA Irradiance using the planned panel angles.

Sanjib Roy has played a significant role in renewable energy skill development, mentoring solar entrepreneurs and engineers through practical training, software-based learning, and entrepreneurship development programs. Industry and institutional profiles describe him as a solar technology mentor and corporate trainer with extensive experience in PV solar system design and business development.
