How will this product support high through put
PV system installation? SS Logo Image

This is the question our team answers at the beginning of our development process for every new Tessolar product. Our goal is factory - efficient installation in the field, and that philosophy is instilled in every Tesserack product. Core to this philosophy is to minimize:

1.  The number of parts
2.  The number of tools
3.  The number of operations

Steel and aluminum have been the go-to material for the solar industry for more than 40 years. While the ease of crossover from other metal industries is expedient, innovation can be limited due to the high cost and complexity of milling and machining features on metal-only systems.

This is why Tessolar uses high strength aerospace composites which enable unlimited design freedom to create valuable innovative gains across the entire racking process — from design and engineering, to racking logistics, to installation.

Material Science Approach

SS Image Logo
  • “No Fear” design philosophy allows use of the entire structural materials toolkit
  • The cost-effective fabrication and assembly of complex components can facilitate vastly simplified installation processes.
  • Composite design is a Tessolar core competency not a commonly found structural design skill set
  • Structural composites are used in everything from air transportation to robotics to wind energy, but have been overlooked by a solar industry that largely does not have composite design competency
  • A Tessolar’s systems design approach also reveals opportunities for innovation in metallic hardware design and composite/metal hybrid racking
