Tape material: For outdoor solar installations, use laminated polyester or polypropylene tape rated for UV and weather exposure. Standard paper labels fade within months.
Tape width: 3/8-inch is standard for wire identification. 1/2-inch and 1-inch tapes work for larger cable bundles and panel labeling.
Print method: Thermal printers need no ink. Ink-based printers offer full color. Manual stamps are cheapest but slowest.
Portability: Desktop printers sit in the office. Handheld and wireless printers work on rooftops and in panels.
Ongoing cost: Calculate tape cartridge costs. Some brands lock you into proprietary tapes. Others accept third-party alternatives.
