Alternative Energy Testing

MET Labs has supported multiple alternative energy initiatives. In the 1980s, MET was one of the first labs involved with alternative energy initiatives, by performing field inspections of wind generators for US Wind Power located at the Altamount Pass in Northern California. MET has also worked with the California Energy Commission, performing field inspections of solar panel installations.

MET tests to these alternative energy standards:

  • UL1703 – Safety of Flat-Plate Photovoltaic Modules and Panels
    • Temperature Test
    • Voltage, Current and Power Measurements Test
    • Leakage Current Test
    • Strain Relief Test
    • Push Test
    • Cut Test
    • Bonding Path Resistance Test
    • Dielectric Voltage-Withstand Test
    • Wet Insulation-Resistance Test
    • Reverse Current Overload Test
    • Terminal Torque Test
    • Impact Test
    • Flame Spread Test
    • Burning Brand Test
    • Water Spray Test
    • Accelerated Aging Test
    • Temperature Cycling Test
    • Humidity Test
    • Corrosive Atmosphere Test
      • Salt Spray
      • Moist Carbon Dioxide/Sulphur Dioxide
    • Metallic Coating Thickness Test
    • Hot-Spot Endurance Test
    • Arcing Test
    • Mechanical Loading Test
    • Wiring Compartment Securement Test
  • UL1741 – Inverters, Converters, Controllers and Interconnection System Equipment with Distributed Energy Resources
    • Anti-Islanding Testing to IEEE 1547.1
  • UL6140 - Outline of Investigation for Wind Turbine Generating Systems
  • UL6141 - Outline of Investigation for Wind Turbine Converters and Interconnection Systems Equipment
  • IEC 61215 – Crystalline Silicon Terrestrial Photovoltaic (PV) Modules - Design Qualification and Type Approval
  • IEC 61646 – Thin-Film Terrestrial Photovoltaic (PV) Modules – Design Qualification and Type Approval
  • IEC 61730-2 – Photovoltaic Module Safety Qualification, Part 2

As part of some of these standards, MET does 85°C/85%RH (relative humidity) testing, utilizing walk-in chambers. 85/85 is the standard test for service life assessment of photovoltaic modules cited in IEC and UL standards. MET can test to any time duration as specified by the client.

"I just wanted to let you know that we had a great experience with your inspector. We just installed 188 solar panels on the roof of a headquarters in Baltimore County. He was extremely knowledgeable about solar installs and was very friendly and easy to work with."
