CSP PV has two basic formats:
1/. Uses a Fresnel lens to focus the sun's rays onto a very small piece of photovoltaic material.
In order for a high-

2/. Uses a reflective “dish” similar to those used for Stirling CSP using glass mirrors.
A recent innovation by Cool Earth Solar has taken a radical approach to building
CSP PV by manufacturing round plastic balloons, to reflect light onto the solar cell
Because its design uses relatively cheap and uses readily available components,
it is estimated these solar concentrators could generate electricity at a cost comparable
to that of natural-
Solarr8 Converts Sunlight Into Both Electricity and Heat!
The five metre long and one meter wide Solar8 produces both 230 V electricity and 50º hot water. Solar 8 is not suited for private homes, but instead is developed for property owners with large building who would like to produce electricity and need heat.

The diagram, below, shows the main components of a parabolic trough type of CSP plant.
Each of the 'solar collectors' is a trough-
Steam that comes out of the turbine is still quite hot. It is fed through a condenser where it is cooled down by cooling water from a cooling tower. The cooled water is fed back into the steam generator and solar superheater to create superheated steam again, and this is fed back into the turbine to generate more electricity.
'Trough systems' use parabolic trough-
'Power towers', for example, use a large field of sun-
