NOVELTY - Double-irradiated near-infrared photon and photovoltaic-energy relay (DIPPER) system, has a body (1) with a top and side cover unit (2) to prevent UV-light from passing into the primary mirror system (3), includes a dichroic-secondary mirror (5) and support (4), to pass photovoltaic photons to the amorphous and monocrystalline silicon layered unit (6) and also to reflect near-infrared photons onto the heat-pipe heat-input section (7). A heat pipe (8) supported by the primary-mirror system transfers heat from the heat-input section of the heat pipe to the heat-output section (9) and into a heat-engine generator-set (10).    USE - For an energy-generating insolation receiver    ADVANTAGE - The double-irradiated near-infrared photon and photovoltaic-energy relay system generated electricity directly from silicon photovoltaic cells and indirectly from a heat-engine generator-set using the near-infrared part of the sun's spectrum.    DETAILED DESCRIPTION - The body also comprises an extensible-mirror system (11) to enable increased capture of insolation, also includes a control unit (12), a wiring-support system (13) for the amorphous and monocrystalline silicon layered unit to allow the photovoltaic current to reach the control box (12) through the hollow mirror support system (14). An optical sun-tracking unit (15) allows the mirror to track the sun and a fibre-optic-cable-mechanical support system (16) passes the insolation received by the tracking unit to the control unit. Arrows (17) indicate the incoming insolation pathway. Arrows (18) indicate the pathway of the incoming insolation after having passed through the UV-light proof material. Arrows (19) indicate the pathway of the photovoltaic photons reflected by the primary-mirror system that pass by the dichroic-secondary mirror support through the dichroic-secondary mirror and onto the amorphous and monocrystalline silicon layered-unit. Arrows (20) indicate the pathway of the near-infrared photons reflected by the primary mirror system that pass by the dichroic secondary mirror support and are reflected by the dichroic-secondary mirror onto the heat-pipe heat-input section. The DIPPER system includes a body with structural support and a top and side cover composed of UV-light proof material. The composite primary mirror receives and reflects UV-light free insolation to concentrate solar energy to make it useful energy. A dichroic mirror system receives, reflects and concentrates near-infrared energy and transmits photovoltaic energy from insolation. A single-crystal and amorphous-silicon layered unit receives concentrated photovoltaic energy passing through a dichroic mirror to generate useful electricity directly. A heat pipe input-section receives concentrated near-infrared photon energy and transfers it through the heat pipe to the heat-pipe output-section. A heat-engine generator-set receives useful energy from the heat pipe and converts it into useful electricity indirectly. An extensible mirror system is located to increase the insolation received in addition to that from the composite primary mirror. A sun tracking system tracks the sun as the earth rotates to provide efficient operation all day long. A control system is located to allow safe control of the unit by an operator.
