Making the honeycomb plate to hyperboloid shape, that means the transverse direction is parabolic surface and the longitudinal direction is spherical surface. Then sticking a thin lens on the surface of the honeycomb plate, the sunlight will convergence at one point. Then the electricity will be generating through the stirling engine.
The plate size is according to the power of generator, for example, 25kw dish plate is about 2.1m2 , the size is 1250 * 2500 and 1550 * 2500.
Applications: heating, hot water, power generation, fresh air ,etc.
Advantages: light weight, easy processing, not easy to deformation, aging resistance, high precision, environmental protection etc.
