The brief is to match , advise and select and source a DC motor which will be coupled to a fan blade, powered only by a photovoltaic solar panel. The product will be used to extract hot air from the roof cavity of a residential house. The housing of the fan, photovoltaic panels and DC motor is not part of the brief. Ideal experience should include an understanding of air extraction by fan where blade and motor characteristics will be important. The intended overall purpose of the design is to install the selected solar photovoltaic, motor and fan blade within a moulding or housing. The device will then be installed in the roof and assist in extracting hot air from the roof cavity on a hot day. Ideally, on a moist winter day the device can extract damp moist air.

Essentials of the Brief is to develop a system which will maximises the time the fan is effective, rather than focus on the maximum air extraction over only a small peak sunlight part of the day.

Further details and specifics of the brief , including a schematic diagram is attached:
