Abstract
Abstract A panel that absorbs solar energy is emplaced as a conventional inclined roof tile with an appearance comparable to that of a tile roof, and comprises a metallic or non-metallic tile which has at least one raised portion (4) that collects heat. A seat is provided for a metallic tube (5) through which flows the fluid to be heated. A transparent cap (7) covers, insulates and protects the raised portion (4) of the tile and the tube. The tile has on its upper surface protuberances (9) connected by conduits (10) permitting circulation of the air contained therein toward the raised collector portion (4) which directly absorbs the solar heat.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
96 words
Solar energy absorptive panel for covering roofs, comprising a tile (2) having at least one downwardly opening raised portion (4) which collects heat, a transparent cap (7) that covers, insulates and protects the raised portion, the tile having at least one protuberance (9) defining a downwardly-opening cavity, said protuberances and raised portion being interconnected by at least one conduit (10) permitting circulation of the air contained in said protuberance so as to transport heat toward said raised collector portion (4), said protuberance (9) being so shaped as to reflect the sunrays toward the raised collector portion.
Claim 2
Dependent Claim
96 words
Solar energy absorptive panel for covering roofs, comprising a tile (2) having at least one downwardly opening raised portion (4) which collects heat, a transparent cap (7) that covers, insulates and protects the raised portion, the tile having at least one protuberance (9) defining a downwardly-opening cavity, said protuberances and raised portion being interconnected by at least one conduit (10) permitting circulation of the air contained in said protuberance so as to transport heat toward said raised collector portion (4), said protuberance (9) being so shaped as to reflect the sunrays toward the raised collector portion.
Claim 3
Dependent Claim
38 words
Panel according to claim 1, and at least one upwardly opening spring clip (6) in said raised portion (4), and a metallic tube (5) seated in said spring clip and through which flows the fluid to be heated.
Claim 4
Dependent Claim
45 words
Panel according to claim 1, in which the protuberances (9) have the form of pyramids, truncated cones, or spherical caps so as to present portions of their external surface perpendicular to the sunrays and to serve as support for the feet of workers during maintenance.
Claim 5
Dependent Claim
23 words
Panel according to claim 1, in which the external surface of the transparent cap is roughened and/or irregular so as to prevent reflection.
