National Semiconductor Acquires Act Solar

National Semiconductor Corp. has acquired Act Solar, Inc. a privately held solar energy company that provides power optimization products and services for commercial and utility-scale solar installations. With the acquisition of Act Solar, National is expanding its solar energy portfolio to include new diagnostics and panel monitoring capabilities for solar arrays in addition to its own SolarMagic technology.

“Now with Act Solar we can further improve the performance and efficiency of solar systems, at the same time providing monitoring capabilities not available before. This will make solar installations more efficient and ultimately reduces the cost of solar energy for everyone,” said Mike Polacek, senior vice president of National’s Key Market Segments.

National’s SolarMagic technology is designed to enhance the efficiency and output of solar arrays when the panels are affected by mismatch issues including shade, debris, different panel types, and panel aging.

Recent internal testing showed that National’s SolarMagic power optimizers recovered 57 percent of power lost due to shade, thereby enhancing the solar installation’s output and efficiency. National Semiconductor said that the SolarMagic power optimizers will begin shipping sometime this spring.
