Embodiment Construction

[0016]A combined diurnal tracking, concentrator, photovoltaic electrical generation system / domestic hot water or space heating solar thermal system is mountable on flat roof industrial buildings; flat roof multi-unit apartment buildings, and pitched roofs of single family residences. The systems, configured in accordance with the principles of the invention, may be exclusively diurnal in which the sun is tracked on a daily basis.

[0017]One aspect of the invention is to achieve a substantial reduction in the cost-per-watt for photovoltaic systems as compared to flat plate panels by reducing the number of solar cells required for a given power output by almost 3 / 1 or 6 / 1. The increased heat generated by a 3 / 1 or 6 / 1 concentration of the sun's insolation on the solar cells may be drawn off by an anti-freeze fluid circulated in an aluminum extrusion, to which the solar cells and the pyramidal concentrator reflectors are attached. This coolant is used to provide domestic hot water heating...

Abstract

An improved diurnal sun tracking system and methodology for use with a photovoltaic solar collector system mountable on flat roof industrial buildings or multi-unit apartment buildings is provided. The improved tracking system and method rotates or pivots the solar collector system to track the sun during the spring and fall Equinoxes in a first tracking mode, as well as from winter to summer solstices, when the angular rate of the sun's movement does not exactly follow the angular rate at the Equinoxes, in a second tracking mode.
