Prepare your learners for real-world success in the fast-growing field of solar energy with Amatrol’s Solar Thermal Troubleshooting – Open-Loop Learning System (950-STOL1). This advanced training solution offers hands-on experience with both draindown and pressurized open-loop systems using real industrial components. Students develop troubleshooting and system operation skills that align with key certifications, including those from the North American Board of Certified Energy Practitioners (NABCEP).

From digital differential controllers and photovoltaic-powered pumps to solar collectors and storage tanks, the 950-STOL1 mirrors the technologies found in today’s solar thermal systems. The included multimedia curriculum provides in-depth instruction using interactive lessons, 3D simulations, and performance-based assessments, ensuring learners gain both conceptual knowledge and technical expertise.

Spanish eLearning Available.

  • Digital differential controller
  • AC and DC centrifugal pumps
  • Temperature probes, flow meters, check valves, and relief valves
  • Vacation bypass and tempering valves
  • Solar storage tank and multiple component circuit panels
  • Photovoltaic panel and two solar collectors
  • Drainback and pressurized open-loop system capabilities

Amatrol’s multimedia eLearning guides learners through solar thermal system operation, freeze protection, draindown configuration, and troubleshooting techniques. The curriculum prepares students for NABCEP certification by reinforcing both foundational concepts and system diagnostics.

  • Solar collector function and control
  • Pump and valve troubleshooting
  • Digital controller programming
  • Freeze protection system diagnostics
  • PV-powered system operation

Open-loop (or direct) solar thermal systems heat water directly through solar collectors and deliver it for immediate use. Unlike closed-loop systems, which use antifreeze mixtures and heat exchangers, open-loop systems offer higher efficiency but require freeze protection measures in colder climates.

  • Solar Collectors
  • Pumps and Valves
  • Solar Storage Tanks
  • Air Vent and Vacuum Valves
  • PV-Powered Solar Thermal Systems
  • Freeze Protection Techniques
  • Digital Controllers
  • Draindown System Operation
  • Troubleshooting and Diagnostics
  • Required:
    • Solar Thermal Sun Simulator (95-STS1)
    • Solar PV-Thermal Sun Simulator (95-STS2)
    • Computer (see Computer Requirements)
  • Recommended:
    • Solar Thermal Cold Water Supply Station (95-STW1)
    • Solar Concepts (950-SC1)
    • Solar Instruments Package for Outdoor Use (95-SIP)
  • Utilities: 120 VAC / 60 Hz / 1 Phase

Each system includes a sample copy of the Student Reference Guide sourced from the curriculum. This professionally bound guide compiles all core technical content for continued learning and review after training completion.
