More solar energy falls on the Sahara Desert in 13 days than the entire planet’s consumption for one year, according to EnergyBiz, a trade publication. Photovoltaic cells provide a viable source of clean energy and have made significant advances in efficiency, but will struggle to become a technology capable of utility-size deployment. Materials required to produce photovoltaic (PV) cells are expensive and are experiencing supply shortages and rising prices.

The most promising sector of the solar space is in concentrated solar technologies – photovoltaic and thermal. At utility-scale, these sources are projected to compete with natural gas fired power plants without subsidies within three years. There are exciting new developments that could see concentrated solar thermal and concentrated solar photovoltaic solar electricity competing with coal-fired power plants within five years. Principle Power’s first solar projects will be utility-scale concentrated solar power plants. These will be located in Spain, Portugal, Italy and Mexico.
