Enphase Energy Inc.

A technique used in PV inverters to extract the maximum amount of power from an array of solar panels.

Small devices installed on solar panels that convert the DC output of a photovoltaic (PV) panel into AC. They use Maximum Power Point Tracking (MPPT) to maximize power extraction from PV arrays.

A device that converts direct current from solar panels into alternating current of the required frequency for supply to the electric grid. It is an essential component of solar PV systems, accounting for 10-15% of overall system cost.

California

A California program providing free solar panel installations to low-income homeowners in disadvantaged neighborhoods, funded by cap-and-trade revenue.

A device that converts direct current from solar panels into alternating current for supply to the electric grid. Essential component of solar PV systems with integrated features such as remote monitoring and optimization.

Rooftop solar photovoltaic systems installed on low-income homes in California, expected to save homeowners $400–$1,000 annually on electricity costs.
