3. Solar Power Basics

Background
Rooftop solar power systems have come a long way, and Westinghouse Solar AC panels break new
ground in both performance and safety. Westinghouse Solar AC panels are the first solar panel on
the market to integrate racking, wiring, grounding and inverters directly into the panel. This
section provides an overview of the installation and operation of your Westinghouse Solar Power
System. Please note that the instructions herein are directed towards individuals and
