Abstract

A solar panel comprises an exterior panel member (2) having an exterior surface profiled to represent a plurality of roof tiles, water passage pipes (3) are located adjacent the interior surface of the panel member in heat exchange relationship therewith to enable solar energy to be transferred to the water in the pipes.

Description

Solar Panels
This invention relates to solar panels, and particularly solar panels adapted to be installed on the roofs of houses.
Known solar panels are typically flat panels which have a very dark, black, exterior surface intended to capture the maximum amount of solar energy possible. Such panels have the disadvantage that they are extremely unsightly. The present invention seeks to provide a solution to this problem.
According to the present im-'ention there is provided a solar panel comprising an exterior panel member having an exterior surface profiled to represent a plurality of roof tiles, and water passage means located adjacent the interior surface of the panel member in heat exchange relationship therewith to enable solar energy to be transferred to the water in the passage means.
Preferably, the water passage means of each panel is adapted to be connected in fluid flow communication with adjacent panels. The passage means may be covered with insulating means on the underside of the panel to prevent the loss of heat from the passage means and valve means may be provided to control the flow of water through the passage means .
A preferred embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which:-
Fig. 1 shows a plan view of the exterior of a solar panel,
Fig. la shows an end section along the lines I-I of Fig. 1
Fig. 2 shows an exterior side view of Fig. 1,
Fig. 3 shows a sectional side view of Fig. 1,
Fig. 4 shows schematically, the under side of the ' panel of Fig. 1
Fig. 5 shows an embodiment incorporating a plurality of panels with their water passages interconnected, and Fig. 6 shows an alternative form of water passage.
Referring now to Figures 1 and 2 in particular, there is shown the exterior surface of a solar panel 1 which has an exterior panel member 2 formed to have the surface profile and general appearance of a roof tile, in this case, the type of tile used throughout the Mediterranean region. This exterior member of the panel may be formed selectively of a number of materials such as glass-fibre reinforced resin, cast aluminium, pressed metal such as aluminium sheet, or moulded plastics material. As shown, the member consists of four rows of roof tiles in two columns although it will be appreciated that- the size of the panel may be chosen in dependence on the particular installation or other practical considerations. The panel is installed in an inclined position with the right hand end 2a being uppermost towards the ridge of the roof, the left hand 2b end being the lower. The panel is designed to lie substantially flush with surrounding conventional roof tiles so as to blend unobtrusively into the roof.
On its underside the panel has a plurality of water passage means 3 in heat exchange relationship with the exterior surface of the panel member. The passages may be formed by standard pipes of plastics or copper or may be cast integrally with the exterior panel member 2. Figure 6 shows a preferred form of pipe in which the water passages are formed in the passages of an extruded aluminium pipe 6 which contains a plurality of passages 7. By providing a flat or oval surface abutting the underside of the roof panel a greater degree of heat transference can be obtained. It is also possible for the profile of the aluminium extrusion to match the profile of the underside of the roof panels to provide even better heat tranference.
The interior surface of the member 2 and the passages is covered by a layer of insulating material to ensure that as much of the solar energy collected as possible is transmitted to the water in the passages. One preferred method of achieving this is to provide a mould onto which the panels are placed so that a space is provided between the underside of the panel and the mould. An insulating material such as plastics foam or mineral wool is injected into the space defined by the mould to adhere to the panel. In certain countries, it is common for the roofs to have an under layer of corrugated iron or asbastos underneath the roof tiles. For such installations, the mould preferably provides a corrugated surface on the insulation so that this is a close fit on the corrugations of the under layer.
At their upper and lower ends, the passages 3 are joined by transverse passages • 4 and δ respectively. The transverse passages are adapted to be connected to corresponding transverse passages of adjacent panels so that a large area of solar energy collector can be assembled to provide the desired amount of heat collection.
Valve means (not shown) may be provided to control the flow of water, which will occur through natural convection, through the passages. The valve means may be a temperature dependent shut off valve and may additionally or alternatively include a non return valve designed to prevent heated water flowing back down the passages when the sun's heat disappears at night. It is, of course, possible to provide a pump for forced circulation if required.
Figure 5 illustrates an alternative arrangement in which a plurality of roof panels 8a and 8b, 14a and 14b, shown in chain dot outline have their pipe runs connected together so that water flows through them in a serpentine path.
Each panel 8a consists of four columns each of which contains a vertical pipe run, adjacent runs being connected at either the top or bottom alternatively to provide the serpentine path. The inlet 9 to the flow path occurs at the bottom left of a first one of the panels of the array. The outlet 10 from this panel is connected to the inlet 11 of the next adjacent panel, which is aligned with the outlet 10. The right hand panel 8b has only three columns of tiles and hence three vertical runs of pipe so that the outlet 12 is adjacent the top of the panel. This facilitates the connection of the pipe to the inlet 13 of a panel 14a on an upper row of panels, also shown in outline only. The panel 14a has four columns so that its outlet 15 is at the lower edge to be joined to the inlet 16 of an adjacent panel. At the left hand end, the panel 14b is of three columns only so that the outlet 17 from the array is at the top. The array includes one or more automatic air bleeds 18.
In the preferred embodiment, the panels are formed from pressed aluminium sheeting which is then etch primed prior to painting with an appropriately coloured matt finish paint. The panel surface may also be treated, for example by shot-blasting, to give a desired appearance. The term roof tile as used herein is intended to include all types of roofing element, including slates and panel elements and also to simulate sections of thatch, -for example .
