1. A solar photovoltaic module comprising:
- a plurality of photovoltaic cells to generate DC power in response to exposure to an amount of sunlight;
a plurality of integrated direct current-to-alternating current (DC-to-AC) inverters, wherein each integrated DC-to-AC inverter comprises (i) a DC input electrically coupled to a single, different photovoltaic cell of the plurality of photovoltaic cells and (ii) an AC output electrically coupled to a corresponding AC output of each other integrated DC-to-AC inverter; and
a first isolation layer, different from the integrated DC-to-AC inverters and the photovoltaic cells, separating each photovoltaic cell from each integrated DC-to-AC inverter.

Abstract
A distributed energy conversion system may include one or more DC power sources and two or more inverters to convert DC power from the power sources to AC power. The AC power from the two or more inverters may be combined to provide a single AC output. A module may include one or more photovoltaic cells and two or more inverters. An integrated circuit may include power electronics to convert DC input power to AC output power and processing circuitry to control the power electronics. The AC output power may be synchronized with an AC power distribution system.
