Extensive Testing

Rain, wind, sleet, snow, heat. Everyday and everywhere, our solar racks are battling the elements. We believe in safety above all else. We perform ongoing extensive testing in these key areas: wind tunnel, structural load, electrical bonding, and life cycle. Here’s what we discovered:

WIND TUNNEL TESTING

  • For all FlexRack Series G systems, atmospheric boundary layer wind tunnel testing has been performed in accordance with section 6.6 of ASCE 7-05, Chapter C31 of ASCE 7-10 and also applicable to the National Building Code of Canada. Accurate 1:60 scale models of the Solar FlexRack were used in the tests. Testing was conducted by CPP.
  • As a result of the tests, the Solar FlexRack engineering team is able to design units with the most realistic wind loads possible. The testing allows potential reduction of wind loading by as much as 32% for exterior ground-mount arrays, and as much as 50% for the interior arrays. In this way, a more cost-efficient racking system can be designed, with the most wind-resistant Solar FlexRacks reserved for exterior arrays.
  • The FlexRack Series TDL also underwent wind tunnel tests to validate the design against actual wind forces. The conclusions for wind loads were based on wind tunnel tests employing procedures that meet or exceed the requirements set out in the American Society of Civil Engineers (ASCE7). Testing was conducted by RWDI.

LOAD TESTING

  • Structural-load testing has been conducted on all FlexRack Series G systems by multiple third-party firms.

UL COMPLIANCE

  • All Solar FlexRack systems have gone through UL testing. Each component-connection point within the racking system conforms to NEC codes for electrically bonded and conductive systems. The testing is performed in accordance to UL 2703 issue 2 specifications. Certification covers both United States and Canada. TUV Rheinland conducted testing.

LIFE CYCLE TESTING

  • We perform ongoing life cycle testing of critical mechanical and electrical components of the FlexRack Series TDL.
