Abstract: A solar power system including a thermal-storage tank installed in the ridge of the roof of a building, and a plurality of solar collector units covered over the roof and outside wall of the building and connected to the thermal-storage tank, wherein each solar collector unit comprises a transparent cover plate with photovoltaic cells for converting the radiant energy of sunlight into electric power, a rear mounting rail, a front mounting frame for engagement with the rear mounting rail of another solar collector unit, a heat-absorber plate having a collector tube connected to the thermal-storage tank, and a lateral mounting frame for connection to another solar collector unit over its heat-absorber plate by screws.

Abstract: A solar collector assembly includes a base frame having a half-round channel body and two side wings, a collector unit supported on two supports within the half-round channel body, two vertically spaced transparent top covers covered over the collector unit, and two end covers sealed at two opposite ends of the half-round channel body and the transparent top covers, wherein the supports can be adjusted to change the elevation and the angle of inclination in the X-axis or Y-axis direction; the base frame has inside space stuffed with a heat insulative material.
