Here Comes the Sun (and the Silicon)

Second, operating costs are extremely low compared to existing power technologies. Third, it’s efficient (six times more than wind power). Fourth, it has great potential. France for example has a total yearly consumption of 350 TWh. If the country covered one-third of its roofs with solar panels, its energy needs would be satisfied. Finally, it’s especially attractive to developing countries. They can quickly adopt SPV technology, skipping over the costly development of large-scale energy networks.

The future’s bright

The complex system built by EFD Induction for Photosil includes: a multi-axis robot, several protective atmosphere vessels, three crucible furnaces, four solid state frequency converters, one high frequency plasma generator, PLC and full control equipment, one special crystallization furnace, a water cooling circuit, and one plasma torch and gas supply panel. Together, this equipment transforms metallurgical silicon into Solar Grade Silicon.

There is no doubt that SPV technology will play a crucial role in energy production in the 21st century. In fact, according to a study by Greenpeace and the European Photovoltaic Equipment Association, SPV systems could be generating as much as 2,600 TWh of electricity around the world by 2030. That would be enough to meet the electricity needs of approximately 14% of the world’s population. And with experimental solar cells already reaching efficiencies in excess of 40%, and governments worldwide pledging financial incentives for solar energy, the future for SPV technology definitely looks bright.
