Microsemi and Spelsberg create strategic alliance for disruptive solar bypass technology


Microsemi has worked with both Spelsberg ELS and Fraunhofer ISE to develop what is says is a “breakthrough solar bypass technology that significantly increases reliability, while reducing power dissipation in the critical bypass diode by up to ninety percent as compared to today’s typical solutions”. The newly developed technology will be used in the company’s solar modules for commercial, residential and industrial applications.

It says it will have a particularly significant impact on the economic models of large-scale solar-energy providers in the power purchase agreement (PPA) market. The resulting reduction in thermal dissipation, says the company, greatly improves reliability essential to solar powered systems’ operational expenses and return on investment.

"Microsemi is excited to bring this new, ground-breaking technology to the solar PV industry," said Paul Pickle, general manager of Microsemi’s Analog Mixed Signal Group. "Our new solar bypass solution will be the first of its kind to address thermal reliability, operational cost and efficiency issues common in solar installations, which will enable improved profitability, a faster break-even time, and improved energy efficiency. Our successful demonstrations at the Photovoltaic Symposium in Bad Staffelstein, Germany, ASES National Solar Conference, and Intersolar shows in Munich and San Francisco are key steps toward deployment of this breakthrough technology."
