Tools for a Successful Solar Electric Install

"The right tool for the job makes all the difference."

We’ve all heard that bit of wisdom thousands of times. And it’s no different for a Solar Electric (PV) system installation than for anything else. Fortunately, most of the tools needed for a PV install are commonly used and easily found. There are very few highly specialized tools. Below are several lists that describe many of the tools needed for an installation. They are broken out into functional groups for site assessment, installation and maintenance. Most of the specialized tools fall into the site assessment and maintenance categories; the installation tools are probably already in your tool box!
