Direct Coupling® Solar PV

Into Building Loads

PRESENTED BY PAUL SAVAGE, CEO

The Idea

Energy costs ↑

Grid reliability ↓

Utilities need reduced peak demand; fixes are complex

Net-Metering is not a sustainable business practice

Billions of Compromises

Better metering, monitoring and control with integrated storage

10% to 50% improvement!

Use power where, when, and how it is generated

Buildings that integrate DG

The Need

Bring Simplicity to These Problems

The Trend
