A solar energy collection system for converting solar energy to electricity that includes solar arrays mounted on a frame. Each array is set on a tracker head that is supported on a pedestal; each pedestal mounts onto a beam. Elevators pivot the arrays, where each elevator is made up of a shaft with a threaded end coupled to a drive nut. An upper end of each drive nut gimbal mounts to a portion of the tracker head; rotating a lower end of each shaft raises or lowers the drive nut, thereby pivoting each array. The vertical shafts are ganged together and driven by a single motor. Further included with each pedestal are azimuth orientation shafts that also mount to each tracker head. Rotating each orientation shaft adjusts an azimuth of an associated array. The orientation shafts are ganged together and are rotated by a single motor.

An aspect of present invention is to provide a temperature control system for a solar cell module, capable of controlling a solar cell module to maintain a proper temperature, the temperature control system comprises: a temperature sensor configured to measure a temperature of the solar cell module; a fluid tube having therein a path along which a temperature controlling fluid flows; a pump configured to supply a temperature controlling fluid which flows along the fluid tube; and an inverter configured to drive the pump such that the temperature controlling fluid is supplied, if the current temperature of the solar cell module is not lower than the pre-stored first pump driving reference temperature, or if the current temperature of the solar cell module is not higher than the pre-stored second pump driving reference temperature.

A new type of PV cell is comprised of a purposefully unique spatial configuration of multiple pairs of transparent thin PV films stacked top down in order of decreasing bandgaps corresponding to increasing wavelengths. Each thin-film pair is made of a material of desirable bandgap, and consecutive films separated from each other in space by a layer of air to force confinement of light waves of wavelength matching bandgap, enabling an infinite number of reflections until the wave energy corresponding to each desired wavelength is absorbed. The PV thin-films are coated to ensure that light of each wavelength is confined as intended. They are passivated to minimize surface recombination. This spatial arrangement provides multiple opportunities for photovoltaic conversion of each intended wavelength hence increasing overall conversion efficiency.
