BACK TO LAB // solar array

Solar array desk.

A photovoltaic array running the real single-diode cell model. Irradiance scales the photocurrent, temperature drops the voltage, and the maximum-power-point shifts with both, so a hot bright panel makes less than its rating. Scrub a real irradiance day, push the array into the heat, and watch the MPP tracker chase the knee.

PANEL FIELD TRACKING

Live tracker field. The sun follows real solar geometry for the scrubbed hour, haze follows the irradiance deficit against clear sky, and the amber DC pulses to the inverter scale with output. Scrub past dusk to stow the field under stars. Switch to 2D for the I-V / P-V curve.
