Tru-Twin x.5: upgrades, by design

Solar sites are built once and then frozen for 25 years. We think they should keep getting better.

Staged Upgrades

More energy from the same site, every generation

Every efficiency gain after commissioning is stranded — unless upgrades are engineered into the product from day one. Tru-Twin x.5 is our staged-upgrade concept: half-generation, drop-in module upgrades that raise a site’s energy yield over its life.

  • Projected +55% energy for roughly +19% system cost at the first upgrade stage
  • Racking, wiring, land, and interconnection all persist across generations
  • Each half-step generation ships as product — revenue at every stage of the roadmap

Upgrade-path details are part of the Tru-Twin™ architecture package, shared under NDA.
