What LibertyCES's vendor documentation shows

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.

Install / Failure Note

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.
