Abstract: An auto-tracking sun solar energy power generator. The power generator includes an eight-diagram-shaped photovoltaic power generator of 8.8 multiples, an eight-diagram-shaped thermal energy generator of 30-50 multiples, a Striling external-combustion photothermal power generator of an eight-diagram-shaped thermal energy generator and a wind-light mutual complementing power generator with the power more than 20 kW. The first three devices are eight-diagram-shaped and of multiple sun structure. The fourth device is a wind-light mutual complementing planar silicon batteries power generator. The first three devices comprise a named multiple suns machine and a named tracking sun machine. The multiple suns machine comprises a metal bracket and planar glass. The tracking sun machine comprises a mechanical drive assembly for tracking sun and a counter-weight.
