The clean energy sector is entering a phase of dramatic change in which business models are being transformed against a backdrop of regulatory uncertainty, as the industry emerges from a challenging period caused by the global economic downtown. Technologies and business structures that were once abandoned, are now being revived in several key sectors.
Concentrated solar photovoltaic energy or CPV is a relative newcomer to the solar power arena and is showing signs of entering into a phase of very rapid growth. It works by concentrating the sun onto a small area of active PV, which operates at around twice the efficiency of normal PV, and promises savings because it requires only a fraction of the photovoltaic material that normal systems require. The DOE has announced a $90 million loan guarantee to support a planned 30-megawatt facility near Alamosa, Colorado.
