The document provides a diagram and description of a photovoltaic solar array system. The system includes 8 solar panels that feed power into an inverter which converts the DC power to 240V AC power. It then connects to the main electrical service panel of a home and includes disconnect switches, grounding conductors, and a bi-directional utility meter to allow excess power to be sold back to the electric company. Safety notes and equipment listings are also included.
