PowerLine solar power management of LED lighting products
PowerLine, solar power management of LED signs and LED lights

The core of our technology is our proprietary programmable integrated circuit board, the PowerLine™ Power Management Unit.   PowerLine™ is the centerpiece of our solar management approach, and provides the foundation for our exclusive customized solar lighting products.  Utilizing PowerLine™, we are able to optimally design our solar-powered systems by minimizing sunlight and input requirements by:

      • Minimizing PV Panel footprint
      • Optimizing number and size of batteries
      • Maximizing solar utilization
      • Maximizing LED brightness and runtime
      • Delivering available energy during low or no-sunlight periods
      • Extending product lifecycle and sustainability
