Maturity stage TRL 8 - Prototype finalized

Daanaa’s novel Power Transaction Unit (PTU) technology performs multiple power electronics functions and data transmission with one programmable module. It consolidates power electronic functions—from bi-directional conversion and amplification to management, transfer, diagnostics, and control—onto a single, high-density, high-efficiency, low-profile, scalable, reliable, and safe component. The PTU enables a less complicated architecture and a common nodal approach to power electronic system design that significantly increases reliability and power transfer efficiency while reducing system design and system operating costs. Daanaa is applying the solution to energy-generating surfaces (including residential PV, VIPV, and BIPV) and automotive applications.

The Environmental Benefits

  • The PTU has the highest voltage conversion rate, highest power density, and highest efficiency compared to the next leading comparable solution
  • Daanaa can complete single-stage conversion, from 400V to 1V with above 90% efficiency
  • Daanaa's PTU is able to generate up to 42% more energy from solar panels based on Independent Third-Party Validated Performance Results
  • When Daanaa’s PTU is integrated into solar panels, owner generation under imperfect weather and solar conditions can be optimized by up to 70%, increasing energy harvest compared to conventional systems
  • In automotive VIPV applications, Daanaa’s solar enabled electric vehicles offer a 69% reduction in GHG emissions as compared to internal combustion engine (ICE) vehicles and a 33% reduction in GHG emissions compared to the today’s EVs

The Financial Benefits

  • Daanaa’s PTU eliminates the need for module-level power electronics (MLPEs) in PV systems, boosting energy yield. By removing MLPEs, PTU-enabled panels simplify installation, reduce operational and maintenance costs, and lower the total cost of ownership
  • Increased energy harvest can reduce the payback period of residential PV systems. PTU-enabled PV modules can improve energy harvest by on average 15% over typical rooftop scenarios and up 42% in heavily shaded conditions
