Abstract
Abstract This apparatus and method for collection of solar energy is particularly adaptable for being formed as a part of or integrated into an upright or vertical surface of a building or structure. The apparatus involves a closed compartment, including an exterior transparent cover, within which are located energy receiving elements, each having an energy receiving surface oriented to efficiently receive solar energy. The apparatus may also include an interior transparent cover and reflective surfaces for further enhancing the characteristics of the collector, and the interior of the apparatus may be evacuated. The method may include the steps of providing a plurality of radiant energy receiving elements, each having an energy receiving surface at the exterior vertical surface of the building, and orienting the energy receiving surface at an angle for efficiently receiving radiant energy.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
213 words
A solar energy collector adaptable for use at an exterior generally upright surface of a building comprising: a compartment having spaced apart exterior and interior covers of essentially transparent characteristics, and means for retaining the compartment at an exterior generally upright surface of a building; at least one energy receiving element comprising at least one solar radiant energy receiving and absorbing surface generally oriented at an angle to the plane of the generally upright building surface for efficiently receiving solar radiant energy according to the position of retention of said compartment at the exterior surface of the building, each energy receiving element also comprising a conduit means connected in heat conductive relationship with each solar energy receiving and absorbing surface, each energy receiving element being retained within said compartment between the interior and exterior cover members with a space on each side of each energy receiving element, the space on each side of each energy receiving element in conjunction with the angular orientation of the solar radiant energy receiving and absorbing surface providing a substantial sight path directly and angularly through said compartment; and means connecting the conduit means for passing a fluid medium through the conduit means and for transporting energy away from each energy receiving element and out of said compartment.
