There are multiple approaches to using solar to create power ... one option is PV (photovoltaic) where panels convert sunlight directly to DC current ... another is CSP (concentrated solar power).

CSP is a form of solar power that uses mirrors to focus the suns rays on panels ... these panels have a heat transfer fluid in them that then is used to generate steam which drives a trubine to produce electricity.

>>> Basically a nuclear type approach with solar replacing the nuclear energy source.

However, an identical solar array fitted with National's SolarMagic power optimizers produced on average between 7 percent and 21 percent more electricity in the same conditions, effectively recouping 54.4 percent of the lost power. National developed SolarMagic technology to improve the energy harvest of solar installations.

Conventional flat PV panels must be mounted at an angle and spaced apart for optimum energy production. The sunlight striking the spaces between the panels is not collected and thus is wasted. Solyndra's panels perform optimally when mounted horizontally and packed closely together, thereby covering significantly more of the available roof area and producing more electricity per rooftop on an annual basis than a conventional panel installation.
