National Semiconductor, SunEdison work to optimize solar arrays

Santa Clara, CA., May 28, 2009 — National Semiconductor Corp. and SunEdison, a solar energy services provider, have initiated field trials to optimize the energy output of solar arrays.

SunEdison initiated field trials in California using National Semiconductor’s SolarMagic power optimizers. National’s SolarMagic power optimizers enable individual solar panels to maximize energy-produced independent of performance of other panels in an array, according to a press release. Individual panels can often under-perform due to shade, debris, panel mismatch or aging.

In March 2008, SunEdison surpassed 100GWh of delivered energy.

To maximize the energy output of each solar photovoltaic (PV) panel in the array, National Semiconductor has developed SolarMagic power optimizers, which enables each solar panel to produce the maximum energy regardless of whether other panels in the array are under-performing due to mismatch.

SolarMagic technology maximizes the energy harvest of each individual PV panel through advanced algorithms combined with leading-edge mixed-signal technology, thereby recouping up to 57 percent of the lost energy due to mismatches, according to the release.
