Working safely with photovoltaics system is critical to everyone. Safety just doesn’t apply to the installer it has to apply tot eh quality of the installation so anyone that comes in contact with the system will also be safe. While I am an avid in teaching DIY and doing DIY projects please understand that when it comes to electricity you need to be safe and following the National Electric Code.
This is a booklet that I picked up somewhere and whenever I teach a solar class this this one of the first handouts I provide.
Credit for this booklet goes to Sandia. I would provide a direct link to the file but I was unable to find the document online.
