Introduction

I have chosen to do my project on solar energy. I believe that solar energy is the best non-conventional resource for the prevision of power in the future of South Africa. The sun is a more reliable source of energy than wind due to the amount of solar rays received opposed to wind.

Brief history of the development of Solar Energy
The first recorded use of utilising the suns power was in the 7th century BC, when magnifying glasses or crystals were used to light fires.
The first person to observe the Photovoltaic Effect was French physicist Edmond Becquerei in 1839.
Though John Ericssobn invented the parabolic though in the 1870’s the first traceable use of them was 1912, when Frank Schyuman set up farms for a small community in Egypt. In 1976 David Carlson and Christopher Wronski manufactured the first amorphous

Plants and animals, alike, use solar energy to produce important nutrients in their cells.
Since solar energy is completely natural, it is considered a clean energy source. It does not disrupt the environment or create a threat to Eco-systems the way oil and some other energy sources might.
Solar energy cells can be used to produce the power for a calculator or a watch. They can also be used to produce enough power to run an entire city.
But at an individual level, everyone is motivated by different things. Some people are interested in solar energy for the environmental benefits, others see solar energy as a way to reduce their electricity costs, and yet others are looking to solar energy as a way to leave a positive legacy for their children

Description of problems encountered when using the source
Solar panels use expensive semi conductive material to generate electricity from sunlight. Semiconductor factories need 'clean' manufacturing environments and are expensive to build &
