A solar condenser apparatus and a construction or structure using the apparatus. The solar condenser apparatus comprises at least one condenser unit. The condenser unit comprises a fixedly arranged linear condenser lens (1) used for condensing sun light in a set range of angles onto a linear light band; a receiver (2), which is arranged at the light band on where the linear condenser lens (1) focuses; and a driver structure (3) matedly connected with the receiver (2). When the position of the sun changes, the linear light band moves along a movement path, the driver structure (3) drives the receiver (2) to track the positional changes of the linear light band and allows the linear light band to be kept focused on a light receiving surface of the receiver. The linear condenser apparatus is fixed and only needs to drive the receiver to follow the focused light band; therefore, the structure of the solar condenser apparatus can be further simplified, and production costs are inexpensive.
