Grounding Made simpler - Part 3: Solar Panels 2022-06-02

To get the paper, click on the orange button at the top of the screen.

The subject of grounding is a complex, multifaceted subject, that is often treated as an after-thought but needs to be considered from the beginning of the design and build process of any DIY Solar/Battery Project.

This is Part 3 of a 4-part series on grounding basics.

1. AC & Household
   Part 1 covers the basics of grounding for household AC systems. Even if you are familiar with house wiring, it is suggested that the reader review this paper to become familiar with the terminology concepts and practices of grounding.
   
   
2. Stationary Systems
   Part 2 introduces the grounding principles of DC wiring, inverters and multiple power sources.
   
   
3. Solar Panels (This Paper)
   Part 3 is a short overview of how to properly ground the frames and mounting racks of Solar arrays.
   
   
4. Mobile Systems
   Part 4 goes through designing the grounding scheme that addresses the unique situations encountered in a mobile system.

Each of the 4 parts are written to be usable and understandable as a stand-alone paper. However, to get a broad understanding of grounding and grounding principles, it is recommended that all 4 papers be read.

Note: This paper only gives a basic overview of grounding concepts and the NEC Grounding requirements. It is NOT a comprehensive review of the NEC grounding requirements.

International Note: This paper is written with a North-American point of view. However, many of the concepts are applicable elsewhere even if the implementation is not.

I would like to give a big shout-out to @Dzl, for his generous help in reviewing and editing the document.
