Power IC helps PV panels harvest maximum energy.

Press Release Summary:

Consisting of highly integrated DC-DC converter, Cell-String Optimizer replaces bypass diode and performs maximum power point tracking deep inside PV module. By replacing each diode with MPPT device, on-off response to performance mismatch is eliminated; every cell-string contributes maximum power without interfering with power production capability of others. IC provides shade mitigation, eliminates hotspots, and minimizes impact of power degradation mechanisms.

Original Press Release:

Solar Panels Gain 30% Additional Power with Maxim's Cell-String Optimizer

First IC to perform MPPT in volume production with top PV module manufacturers

SAN JOSE, Calif. and LAS VEGAS, -- New cell-string optimizer technology from Maxim Integrated Products, Inc. (NASDAQ: MXIM) allows photovoltaic (PV) panels to harvest significantly more energy and simplifies design complexity for solar installation projects.

Maxim's cell-string optimizers are highly integrated DC-DC converters that replace the bypass diode and perform maximum power point tracking (MPPT) deep inside the PV module. By replacing each diode with a MPPT device, the on-off response to performance mismatch is eliminated; every cell-string contributes maximum power without interfering with the power production capability of others. This enhanced degree of flexibility leads to increased energy production; eliminating collateral performance loss due to module mismatch, degradation, soiling, localized shading, and row shading loss mechanisms.

Based on the company's industry leading power semiconductor technology, Maxim's cell-string optimizer is the first integrated power IC to perform MPPT and first to be embedded within the PV module.

Key Advantages

Increases Energy Harvest: Offers best-in-class shade mitigation, providing 30% additional power over diodes

Extends Reliability: Eliminates hotspots and minimizes the impact of power degradation mechanisms

Enables Flexible Design: Higher degree of flexibility to incorporate multiple string lengths, multiple orientations, and expanding modules into partially shaded areas

Simplifies Operation: Fully integrated solution simplifies design by requiring no additional hardware, specialized inverters, or data services


"The granularity of Maxim's cell-string optimizers offers best-in-class shade mitigation, enables flexible system design without adding complexity, and helps improve panel lifetime performance," said Seth Kahn, Executive Director, Solar Products, Maxim Integrated. "Major PV module companies have recognized the advantages of this unique technology—the first integrated power semiconductor for MPPT—and are ramping it in volume production."
