Company�s proprietary patent-pending technology enables maximum energy harvesting and significantly reduces the number of payback-years for PV installations
The Company�s proprietary patent-pending technology is named  P-CUBED which stands for �Photovoltaic Power Processor.� P-CUBED involves digital PV power processing and synthesis. This enables maximum harvesting of energy from the sun and provides grid-tied AC power compatible with utility. P-CUBED offers a low cost and effective PV solution and it significantly reduces the number of payback years. The advantages of P-CUBED:

�
�System 
- Much easier system design
�- Multiple roof facets can be used for residential installations
�- Quick installation and commissioning
- Quick identification of a failed or weakened PV module in a large installation (e.g. solar farm) 
�- No single point of failure
�

Efficiency, scaling and retrofits
� - Module mismatch will not affect system
� - Module operation independent of neighboring modules
� - Easily scalable -- enables "pay as you go" system integration
� - Easy repairs and retrofits
�

Safety & cost savings
� - Most effective balance of system (BOS)
� - Additional safety features for installers and firefighters in residential installations
� - Cost savings on wiring, diodes, and other hardware

The graphs below show the number of payback years (without any government subsidies or tax credit) vs. system cost to the end user for various localities as well as the number of payback years vs. number of daylight hours.
Number of payback years vs. system cost in $/W(AC) for conventional installations and P-CUBED. The number of payback years for both cases depends on the number of daylight hours and varies from region to region.
Number of payback years vs. daylight hours per day for conventional installations and P-CUBED

The Company�s base product can be configured to serve several voltage levels suitable for both residential and commercial markets:

  • 120V single phase
  • 240V split phase
  • 208/120V three phase
  • 480/277V three phase
