FIELD OF THE INVENTION
This invention relates to a Solar Home Lighting system which provides illumination powered from the sun’s renewable energy, the solar cells in the system convert the sun’s energy directly to electricity.
BACKGROUND OF THE INVENTION
Solar Home Lighting System is the perfect compact solution for an independent power supply in remote locations where electricity is unavailable, unreliable or expensive. All systems are professionally designed for lighting purpose.
It is known to provide lighting by using a solar cell to maintain charge in a battery during daytime and to use the battery to power a light for illumination during night time. Such solar lights may operate continually over several months, or more, automatically and without manual supervision or attention. It is known to arrange for the solar light to be sensitive to the level of daylight in its environment to turn ON and OFF automatically and/or be provided with a built-in timer circuit that turns the light ON and OFF for chosen periods of time within each daily cycle. Present day solar lights are usually stand alone items that are positioned or mounted near a drive way or footpath, for example, to provide suitable

illumination when required. This means the solar lights must be supported in some way and leads to certain limitations of use.
