Technology
Most solar parks use ground mounted (sometimes called free-field or stand-alone) arrays. They can either be fixed tilt or tracking, either single axis or dual axis. Tracking increases the output, but also the installation and maintenance cost.
The DC power output of the solar arrays is converted to AC by inverters, and connection to the grid is through a high voltage three phase step up transformer, usually to 10 kV or above.

Famous quotes containing the word technology:
“The real accomplishment of modern science and technology consists in taking ordinary men, informing them narrowly and deeply and then, through appropriate organization, arranging to have their knowledge combined with that of other specialized but equally ordinary men. This dispenses with the need for genius. The resulting performance, though less inspiring, is far more predictable.”
—John Kenneth Galbraith (b. 1908)
“Our technology forces us to live mythically, but we continue to think fragmentarily, and on single, separate planes.”
—Marshall McLuhan (1911–1980)
“Radio put technology into storytelling and made it sick. TV killed it. Then you were locked into somebody else’s sighting of that story. You no longer had the benefit of making that picture for yourself, using your imagination. Storytelling brings back that humanness that we have lost with TV. You talk to children and they don’t hear you. They are television addicts. Mamas bring them home from the hospital and drag them up in front of the set and the great stare-out begins.”
—Jackie Torrence (b. 1944)
