CASE STUDY: Unreliable solar power at a well pad can quickly become a production and safety problem.
In Haynesville, an upstream operator upgraded from pneumatic dump valves to electric valve actuators to reduce methane venting, but the new critical loads (ESD solenoid + PLC/modem) were still vulnerable to intermittent solar and battery performance. The result: unpredictable failures, field call-outs, and real shut-in risk.
The fix was a hybrid approach: a Model P-5100 TEG configured as an H-TEG (Hybrid Solar TEG) to support and stabilize the existing solar system, float-charge batteries, and keep power consistent through weather swings.
After installation, technician call-outs due to power outages were eliminated and battery voltage remained fully charged day and night.
