Cooling Photovoltaic Systems Using Capillary Fibres

摘要

A system for cooling photovoltaic cells 1 including a reservoir 4 which supplies water to capillary fibres 2 behind the PV cells. The moisture at the capillary fibres reduces the temperature of the PV cell due to evaporation. The reservoir may be located above the PV cells and may be refilled periodically. The capillary fibres may be supplied with water using nozzles to spray water onto them; an anti-drop valve provides permanent pressure in the system. The water supply may be controlled by a computerized system. The temperature surrounding the PV cell may be measured using a wet thermometer.
