Enterprise power, aimed at the wrong trade.
ServiceTitan is deep and well-funded, but it was built for HVAC, plumbing, and electrical operations, priced for high-volume shops, and it typically carries a paid implementation before you go live. There is no solar-specific workflow and no PV production monitoring.
SolarProjeX is lean and solar-native. You start on a free trial, not a sales cycle and an implementation invoice, and every part of the product, from job types to monitoring to paysheets, is shaped around how solar service actually runs.
