The right tool makes Solar 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!
Site Assessment Tools
50-100 ft. tape measure
Solar Pathfinder (evaluates the solar energy potential at a site)
Compass (not needed if you’re using a Solar Pathfinder)
Maps (reference for location latitude and magnetic declination)
Digital camera
Basic Tools Needed for Installation
Angle finder
Torpedo level
Fish tape
Chalk line
Cordless drill (14.4V or greater), multiple batteries
Unibit and multiple drill bits (wood, metal, masonry)
Hole saw
Hole punch
Torque wrench with deep sockets
Nut drivers (most common PV sizes are 7/16”, ½”, 9/16”)
Needle-nose pliers
Lineman's pliers
Slip-joint pliers
Small cable cutters
Large cable cutters
Hacksaw
Tape measure
Blanket, cardboard or black plastic to keep modules from going “live” during installation
Heavy duty extension cords
Caulking gun
Fuse Pullers
Additional Tools to Consider (especially for multiple installations)
DC clamp-on ammeter
Reciprocating saw / Jig saw
Right angle drill
Conduit bender
Large crimpers
Magnetic wristband for holding bits and parts
