Abstract
Abstract A closed core base having concave channels in its top face is fitted with a thermoplastic lens having corresponding convex channels. The channels form transfer passages which carry a liquid medium which absorbs solar energy as it flows through the passages. The base consists of an insulating core material having an outer skin fabricated in a solar absorbant color. The sides of the base are sloped for stacking and extend above the top of the conduit to support a clear cover. The core of the base is coated with a reflective material and filled with insulating material.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
143 words
A solar collector panel comprising: a. a base made of structural foam having a top with concave channels therein and having a manifold concave channel along the perimeter of said concave channels and connecting said concave channels, said base having an entry access hole connected to said manifold concave channel and having an exit access hole connected from said manifold, concave channel; and b. A thermoplastic lens bonded to the top of the base adjacent on each side of said channels and spanning the concave channels of the base, whereby the channels form transfer passages which carry a liquid media which absorbs solar energy as it flows through the passages, said thermoplastic lens disposed for expansion or contraction in response to expansion or contraction of said liquid media and having an ovular configuration which will enhance incident angle absorption responsive to said expansion.
Claim 2
Dependent Claim
143 words
A solar collector panel comprising: a. a base made of structural foam having a top with concave channels therein and having a manifold concave channel along the perimeter of said concave channels and connecting said concave channels, said base having an entry access hole connected to said manifold concave channel and having an exit access hole connected from said manifold, concave channel; and b. A thermoplastic lens bonded to the top of the base adjacent on each side of said channels and spanning the concave channels of the base, whereby the channels form transfer passages which carry a liquid media which absorbs solar energy as it flows through the passages, said thermoplastic lens disposed for expansion or contraction in response to expansion or contraction of said liquid media and having an ovular configuration which will enhance incident angle absorption responsive to said expansion.
Claim 3
Dependent Claim
33 words

Claim 4
Dependent Claim
30 words
The solar collector panel is described in claim 1, wherein said base is monolithicly formed from a plastic resin impregnated with a solar absorbant color and a sunlight ageing inhibitor.
Claim 5
Dependent Claim
21 words
The solar collector panel as described in claim 1, wherein said base has a durable skin which provides support and waterproofing.
Claim 6
Dependent Claim
22 words
The solar collector panel as described in claim 1 wherein said base is fabricated to have a separately defined inner core section.
Claim 7
Dependent Claim
19 words
The solar collector as described in claim 5, wherein said inner core is coated with a solar-ray reflective material.
Claim 8
Dependent Claim
19 words
The solar collector panel as described in claim 5, wherein said inner core section is comprised of heat insulation.
Claim 9
Dependent Claim
29 words
The solar collector panel as described in claim 1, wherein said channels are diagonally parallelly oriented, thereby allowing the solar collector panel to be mounted on a sloping plane.
Claim 10
Dependent Claim
36 words
The solar collector panel as described in claim 1, wherein said access holes are selectively located in the side and in the bottom of the base, and include female threads for engagement by male threaded tubing.
Claim 11
Dependent Claim
30 words
The solar collector panel as described in claim 1, wherein said thermoplastic lens is shaped to form convex channels which are in registry with the concave channels of the base.
Claim 12
Dependent Claim
22 words
The solar collector panel as described in claim 1, wherein said access holes are located in diagonally opposite corners of the base.
Claim 13
Dependent Claim
116 words
A solar collector panel comprising: a. a skin-covered foam base, said skin impregnated with a solar absorbant color, said base having a top with parallel, diagonal concave channels therein, an inner core of heat insulation, a solar-ray reflective material, coated on said inner core, and female threaded access holes selectively located in the side and the bottom of the base leading to the channels; and b. a thermoplastic lens bonded to the top of the base, said lens forming parallel, diagonal, convex channels which are in registry with the parallel, diagonal concave channels of the base, whereby the channels form transfer passages which carry a liquid media which flows through the passages and absorbs solar energy.
Claim 14
Dependent Claim
116 words
A solar collector panel comprising: a. a skin-covered foam base, said skin impregnated with a solar absorbant color, said base having a top with parallel, diagonal concave channels therein, an inner core of heat insulation, a solar-ray reflective material, coated on said inner core, and female threaded access holes selectively located in the side and the bottom of the base leading to the channels; and b. a thermoplastic lens bonded to the top of the base, said lens forming parallel, diagonal, convex channels which are in registry with the parallel, diagonal concave channels of the base, whereby the channels form transfer passages which carry a liquid media which flows through the passages and absorbs solar energy.
Claim 15
Dependent Claim
38 words
The solar collector panel as described in claim 12, wherein said base further comprises sloping sides which extend above the top of the parallel, convex channels of the thermoplastic lens, said sloping sides removably supporting a clear cover.
