MICROINVERTERS AND POWER OPTIMIZERS: POWER CONVERSION MIGRATES DOWN TO THE PV PANEL

- BY MARGERY CONNER •TECHNICAL EDITOR
ALTERNATIVE FORMS OF POWER HAVE BECOME INCREASINGLY POPULAR AS UTILITIES REACT TO RISING FUEL PRICES AND GOVERNMENT MANDATES. PHOTOVOLTAIC CELLS USUALLY RECEIVE MOST OF THE ATTENTION AS SOLAR-ENERGY COST DRIVERS, BUT THE AC/DC INVERTER DESIGN IS EQUALLY IMPORTANT TO OVERALL SYSTEM EFFICIENCY AND COST.
