Problems solved by technology

In the case of cells forming a large module or panel, as is often the case, damage to a single cell or small area of ​​the module or panel will render the entire module or panel inoperable
In these cases, the entire module or panel usually needs to be replaced, often at significant cost
[0005] The disadvantages of the known PV module or panel configurations described above are particularly acute in the case of roof mounted modules or panels
In this case, due to reasons such as from large hailstones or destructive behavior in which vandals throw hard objects such as stones or bricks onto the roof-mounted unit, or due to workers or others Or the cause of walking or falling on the module or panel, the module and panel are easy to break

Embodiment Construction

[0026] figure 1 The solar energy harvesting device 10 seen in is designed to form part of the roof covering structure, i.e. the device will actually form part of the roof covering, usually at the edge of the roof covering which may for example consist of tiles, sheet metal, etc. between adjacent areas.

[0027] figure 1 The number 12 in represents a batten or purlin, typically timber, which spans transversely over the rafters (not shown) in conventional pitched roof construction.

[0028] System 10 includes a rigid support structure generally indicated by numeral 14, which includes an elongated extruded member 16 of material having a high thermal conductivity grade, in this case aluminum. Part 16 enters along the figure 1 elongate in the direction of the paper surface.

[0029] In the illustrated embodiment, each extruded part 16 consists of two extruded subparts 16.1 and 16.2, in figure 2 and 3 The subcomponents 16.1 and 16.2 are illustrated on a larger scale in . The...

Abstract

The invention concerns a solar energy collection apparatus which is capable of producing electricity and hot water. The apparatus (10) includes a rigid support structure (14) which can be mounted to form part of a roof cladding structure. It includes rigid support components (16) made of thermally conductive material which are connected releasably to one another. Photovoltaic (PV) cells (42) mounted on the components of the support structure in heat transmitting relationship with the components. Thermally conductive conduits (48) are provided. These are connected to the components of the support structure in heat transmitting relationship with the components and are arranged to convey water to remove heat from the PV cells via the components and conduits. A removable, light-transmitting cover is spaced above and extends over the PV cells.

Description

technical field [0001] The present invention relates to solar energy collection devices. Background technique [0002] Photovoltaic (PV) cells are widely used to convert solar energy into electricity. However, such cells are known to be relatively inefficient to the extent that, under typical conditions, PV panels can only convert about 15% of incident solar energy into electricity, with the remainder being dissipated as heat. It is also well known that the efficiency of PV cells decreases with increasing temperature. For example, it is said that the electrical power produced by PV cells decreases by 0.5% for every degree Celsius increase in temperature. [0003] For these reasons, considerable research has been done on the dissipation of heat generated by PV cells. Currently, research is mainly focused on improving heat removal from PV cells using natural convection. In these solutions, an air gap or air gap is formed under and possibly around the PV panel so that natur...
