Design performance description:

a.Ventilation system powered by pure photovoltaic panels installed on the roof (no battery pack required).

b. The system is equipped with 150W photovoltaic panels.

c. The system is equipped with a 135W patented disc motor.

d. The system requires that the weak sunlight in the early morning can start to exhaust the air at a low speed to avoid the accumulation of heat in the space. When the sun is sufficient, the system can rotate at 1400 rpm and automatically exhaust the air at high speed.

e. The speed and exhaust volume of the system all depend on the intensity of sunlight
