Abstract

An apparatus combining a solar tracker and a dual heat source collector includes a heat engine assembly and the solar tracker. The heat engine assembly includes a heat collector, a heat collecting lens, and a heat engine. The heat collector includes a solar heat collecting room and a heat source room. The heat collecting lens is arranged on the heat collector and corresponds to the solar heat collecting room. The heat engine is located in the solar heat collecting room. The solar tracker includes a primary mirror, a secondary mirror, a pivot member, and a driving member. The primary mirror has a first reflective surface and a back surface. The primary mirror has a mounting hole passing through the primary mirror. The secondary mirror is mounted above the primary mirror.
