Solar is named directly in Graco's PR-X/PR-Xv market list. Real application logic: PV module framing and junction-box potting is two-component silicone or urethane work where off-ratio material becomes a field warranty failure — exactly what the FIFO path and fixed/variable ratio control address.

Real Specifications
| Target markets (Graco-stated) | Electronics, EV battery, general industry, solar, telecommunications | graco-sealants-adhesives.md |
| PR-X Fixed Ratio product line | 4 real product options (configurator-driven) | graco-sealants-adhesives.md |
| PR-Xv Variable Ratio product line | 6 real product options (configurator-driven) | graco-sealants-adhesives.md |
| Fluid path design | Patented FIFO (first-in-first-out) fluid path — prevents material blocking/curing inside the pump | graco-sealants-adhesives.md |
The same FIFO fluid path that protects PR-X/PR-Xv on electronics duty prevents in-pump curing on the silicones and urethanes solar module encapsulation runs — a cured-in-place fluid path on an intermittently run line surfaces as a bad seal.
Solar heads its own line in Graco's PR-X/PR-Xv target-market list alongside EV battery and telecommunications — real vendor confirmation, not an assumed fit. PV module framing and junction-box potting are two-component silicone/urethane jobs; the FIFO fluid path is what keeps that material from curing inside the pump between shots.
