Maxim's cell optimizers are DC-DC converters that replace the bypass diode and achieve Maximum Power Point Tracking (MPPT) within the photovoltaic module. By replacing each diode with an MPPT device, the on/off response to performance phase shifts is eliminated; each row of cells contributes maximum power without interfering with the energy production capacity of the others. This greater degree of flexibility leads to increased energy production by eliminating collateral performance losses due to module mismatch, degradation, soiling, localized shading, and shading loss mechanisms.
Based on the company's industry-leading power semiconductor technology, Maxim's cell optimizer is the first integrated power IC to perform MPPT and the first to be incorporated within the photovoltaic module.
"The granularity of Maxim's cell optimizers offers best-in-class shade mitigation, enables flexible system design without adding complexity, and helps improve panel lifetime performance," says Seth Kahn, Executive Director for Solar Products, Maxim Integrated. "Largest photovoltaic module companies have recognized the advantages of this technology—the first single integrated power semiconductor for MPPT—and are ramping up production volume."
