The invention relates to a method of increasing the amount of light energy falling on a solar cell or cells 4, also known as a photovoltaic (PV) cells, by the use of a reflector or reflectors. A single cell or a number of cells may be arranged to form a solar panel. Preferably, the reflectors are made of light weight materials, are concave or parabolic in shape, can be folded flat to assist portability, and are optimised to collect the available light over a given period of time without the need for equipment to track the sunlight. Furthermore, the reflector(s) may comprise one reflective surface only or be made up of a number of small reflectors. A system of solar cells and reflectors may be integrated into one unit. The reflectors may be made from materials such as plastics, glass or metals, for the optimisation of the light wavelength required by the solar cells. Preferably, the solar cell or cells are incorporated into a hybrid system, where the energy obtained from a cooling system used to cool the solar cell or cells is used to generate hot water. |
