Rctd-031 -

Three prototypes (A‑C) were mounted on a rooftop at the Berkeley Climate Research Facility (latitude 37.87° N). Data loggers recorded ambient temperature, sky temperature (via a chilled‑mirror radiometer), solar irradiance, device surface temperature, and electrical output at 1‑minute intervals for 90 days (June–August 2025).
