Abstract
Abstract A solar energy collector device is disclosed for selectively collecting an electrical energy and a thermal energy at the same time from a solar energy. The device comprises an inorganic-and-metal composite in the form of a roof tile or a wall-forming member which includes a solar battery exposed to sun rays and a heat medium passageway disposed underneath the battery. The density of distribution of a particulate inorganic substance within a metal mass is varied through the areas of the tile or wall member so as to effectively collect the respective energies without adversely affecting the interior conditions of a building in which the device is installed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
71 words
A solar energy collector device comprising a composite material comprising a particulate inorganic substance and a metal in the form of a roofing tile or an exterior wall member, at least one solar battery disposed on an outer surface of said tile or wall member exposed to sun rays, and a heating medium passageway underlying at least the region of said tile or wall member where said solar batteries are located.
Claim 2
Dependent Claim
71 words
A solar energy collector device comprising a composite material comprising a particulate inorganic substance and a metal in the form of a roofing tile or an exterior wall member, at least one solar battery disposed on an outer surface of said tile or wall member exposed to sun rays, and a heating medium passageway underlying at least the region of said tile or wall member where said solar batteries are located.
Claim 3
Dependent Claim
46 words
A solar energy collector device as claimed in claim 1 wherein said particulate inorganic substance is selected from the group consisting of Shirasu balloon, tuff loam, diatomaceous earth, and glass fiber, and said metal is selected from the group consisting of aluminum, copper, and their alloys.
Claim 4
Dependent Claim
47 words
A solar energy collector device as claimed in claim 1, wherein the density of distribution of said particulate inorganic substance in said composite material is higher at the portion of said tile or wall member which underlies said passageway than at the portion which overlies said passageway.
Claim 5
Dependent Claim
69 words
A solar energy collector device as claimed in claim 1, wherein said heating medium passage is comprised of a forward path extending underneath said solar batteries and a return path extending through the areas of said tile or wall member which are devoid of said batteries, the density of distribution of said inorganic substance in said composite material being higher at said forward path than at said return path.
Claim 6
Dependent Claim
118 words
A solar energy collector device comprising a composite material comprising a particulate inorganic substance and a metal in the form of a roofing tile or an exterior wall member, at least one solar battery disposed on an outer surface of said tile or wall member exposed to sun rays, and a heating medium passageway underlying at least the region of said tile or wall member where said at least one solar battery is located, said tile or wall member having an upper cutaway recess and a lower cut-away recess formed in diagonally opposed corners of said tile or wall member and a connecting port at an end face of each of said cut-away recesses communicating with said passageway.
Claim 7
Dependent Claim
118 words
A solar energy collector device comprising a composite material comprising a particulate inorganic substance and a metal in the form of a roofing tile or an exterior wall member, at least one solar battery disposed on an outer surface of said tile or wall member exposed to sun rays, and a heating medium passageway underlying at least the region of said tile or wall member where said at least one solar battery is located, said tile or wall member having an upper cutaway recess and a lower cut-away recess formed in diagonally opposed corners of said tile or wall member and a connecting port at an end face of each of said cut-away recesses communicating with said passageway.
Claim 8
Dependent Claim
22 words
A solar energy collector device as claimed in claim 1 or 5 wherein said passageway is in the form of a conduit.
Claim 9
Dependent Claim
23 words
A solar energy collector device as claimed in claim 1 or 5 wherein said passageway is in the form of an open channel.
