Summary
Field measurements over ten days on a small solar chimney model (7 m collector, 6.5 m tower) show that morning condensation on the canopy cuts radiation transmittance by roughly 10% and keeps collector air several degrees cooler until the film evaporates, postponing power generation by about three hours; pre-dawn auxiliary heating is suggested to clear the film.
