An integrated wind and solar solution is provided, including a solar energy collection assembly (100) and a vertical axis wind turbine (400), combined to provide an integrated power output. In preferred embodiments, the vertical axis wind turbine is positioned above the solar energy collection assembly. Concentrating solar mirror collectors (116) are used to direct sunlight to a heat engine (250), which converts the collected heat energy into rotary motion. Rotary motion from the heat engine and from the vertical axis wind turbine preferably are on the same rotating axis (600), to facilitate load sharing between these two sources. A dual axis azimuth-altitude solar panel alignment tracking system is used in order to boost the energy conversion capability of the solar energy collectors.

A system and method for solar energy concentration is provided. One embodiment has a reflective trough with a reflective upper surface that reflects incident sunlight energy towards a focal line; a solar evacuated tube heat collector defined by a transparent fluid container member that has a length that corresponds to a length of the reflective upper surface of the reflective trough, wherein the solar evacuated tube heat collector is located along the focal line associated with the reflective trough such that an interior of the transparent fluid container member encompasses the focal line; and a wave guide located above and in proximity to the solar evacuated tube heat collector having a length corresponding to the length of the solar evacuated tube heat collector, wherein a lower surface of the wave guide has a reflective lower surface that reflects incident sunlight energy downwards onto the solar evacuated tube heat collector.
