An apparatus for converging solar radiation includes a base which has a heating portion disposed thereon. Two supporting stands are oppositely pivotally mounted a top of the base. Two sensing sheets respectively oppositely disposed on two sides of each supporting stand. Each sensing sheet has a first end mounted on the supporting stand and a second end of the sensing sheet has an elastic unit connected thereto. A converging lens is pivotally mounted on the supporting stands. The converging lens is connected to the elastic units such that the converging lens is located above the heating portion. The sensing sheets slightly expanded and stretched when heated such that the elastic units are driven by the heated sensing sheets to pull the converging lens to incline toward the heated sensing sheets for tracking movement of the sun to maximize absorption of solar radiation.
