New Type of Solar Array Provides Twice as Much Power as Normal Panels

 
Researchers at the University of Arizona have developed a new method for turning solar energy into useable electricity. They have designed a solar module which works rather like a telescope. It uses a curved mirror to focus sunlight onto a small glass ball which then spreads the light evenly across a solar panel made up of high efficiency solar cells, normally only used in space. The whole module can provide twice the power output of a normal solar panel.

The solar panel is mounted on a frame which tracks the sun during the day. Blak Coughenour, a graduate student at the University’s College of Optical Sciences, explained that “the tracker is fully automated. The system wakes itself up in the morning and turns to the East. It knows where the sun will rise even while it’s still below the horizon. It tracks the sun’s path during the day all the way to sunset, then parks itself for the night.”

Mirrors are already used in solar thermal plants, but this mirror had to be specially designed. Normally mirrors are used to focus the heat from the sun onto a specific point, such as a pipe, but this mirror was designed to concentrate the sunlight.
