Abstract

Abstract A solar energy system is provided in which a solar collector is positioned inside what would be the attic under a conventional roof of a building. The inside surfaces of the roof rafters and top surfaces of the ceiling joists are utilized to mount reflective surfaces thereon to reflect and focus incoming rays from the sun onto a small collector mounted on the ceiling joists of the structure. These reflective surfaces mounted in the attic form a pyramidal reflector which focuses the sun''s rays onto the collector. A movable hinged reflective panel which forms the base of the pyramidal reflector when closed is opened and closed by a geared electric motor. This movable reflective panel is opened when the sun is out, and may be closed when it is cloudy, or at nighttime. It may also be positioned at an optimum angle, depending upon the elevation angle of the sun. The solar collector may be utilized to heat a medium for providing a heating and hot water system for the structure, as well as providing cooling and/or air conditioning, and/or may include solar cells for generating electricity from the collected sun''s rays.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 138 words
A solar energy system for a structure, comprising a. a structure having a wedge-shaped space formed between a roof and a base member, b. a pyramidal reflector having reflective interior surfaces formed in said wedge-shaped space and mounted underneath said roof and on top of said base member with the base end of the pyramidal reflector facing the sun''s position near winter noon, c. a movable reflective panel forming said base end of said pyramidal reflector adapted to open and close said pyramidal reflector to the solar energy of the sun for optimizing solar energy collection based on the angle said panel makes with the direction of the sun, and d. a solar collector mounted in said pyramidal reflector for receiving and converting solar energy focused thereon by said pyramidal reflector when said movable reflective panel is open.
Claim 2
Dependent Claim 138 words
A solar energy system for a structure, comprising a. a structure having a wedge-shaped space formed between a roof and a base member, b. a pyramidal reflector having reflective interior surfaces formed in said wedge-shaped space and mounted underneath said roof and on top of said base member with the base end of the pyramidal reflector facing the sun''s position near winter noon, c. a movable reflective panel forming said base end of said pyramidal reflector adapted to open and close said pyramidal reflector to the solar energy of the sun for optimizing solar energy collection based on the angle said panel makes with the direction of the sun, and d. a solar collector mounted in said pyramidal reflector for receiving and converting solar energy focused thereon by said pyramidal reflector when said movable reflective panel is open.
Claim 3
Dependent Claim 22 words
The structure set forth in claim 1 wherein said solar collector includes a plurality of solar cells for the generation of electricity.
Claim 4
Dependent Claim 48 words
The structure set forth in claim 1 wherein said solar collector has a selectively blackened surface having an absorptivity of 0.9 in the visible spectrum from 0.3 Mu to 0,9 Mu and having an emissivity approaching 0.1 in the infrared spectrum from 3 Mu to 15 Mu .
Claim 5
Dependent Claim 21 words
The structure in claim 1 where the solar collector includes one or more transparent cover plates made of glass or plastic.
Claim 6
Dependent Claim 32 words
The structure in claim 4 where the glass or plastic plate or plates are coated for maximum transmission in the visible and optimum reflection back onto said solar collector in the infrared.
Claim 7
Dependent Claim 37 words
The structure set forth in claim 1 having a motor coupled to said movable reflective panel for controlling the positioning of said roof panel to maximize the amount of solar energy collected at any time or season.
Claim 8
Dependent Claim 19 words
The structure set forth in claim 1 wherein the reflective surfaces of said pyramidal reflector are corrosion protected aluminum.
Claim 9
Dependent Claim 17 words
The structure set forth in claim 1 wherein said pyramidal reflector is formed of aluminized plastic material.
Claim 10
Dependent Claim 35 words
The structure set forth in claim 1 wherein when the sun is high said reflective panel is opened for directing the energy emitted by said solar collector to the cold sky for cooling said building.
