Examples of photovoltaic cells Photovoltaic cells are cells made of semiconductor material like silicon. They generate electricity from radiation the sun gives off. 72 photovoltaic cells can be joined together to form a solar module, these can in turn be joined together to create a solar panel also called solar arrays. The larger the solar array, the more electricity that can be produced.
The school is involved in a program run by Genesis Energy – Schoolgen. The question of sustainability and environmentally-friendly energy has been looked at before at Raphael House. A group of class 12’ers looked at solar power and made suggestions as to how Schoolgen could make improvements. Elwin Burger made a solar powered USB charger for electrical devices such as iPods. The schoolgen program has generated a Total of kWh | tonnes CO2 saved
Insert data from Chloe promised to be ready by Friday.
Only about percent of the energy absorbed by PV cells actually ends up as electricity. The energy used to create solar cells including mining Silicon, fabrication etc. is generated by the cell in 1-2 years. Solar cells last around years Sun is a variable
Oil has peaked Subsidies by government Getting cheaper to make. Soon it might be the main power source. You could have a house like this
