The ECH^™ is installed in combination with a Photovoltaic Solar Energy Electrical Generation System...
The ECH^™ Continues to Recover, Recycle & Convert Wasted Untapped Heat Energy Into Electricity, Even After The Sun Goes Down!  

 The Upper ECH^™ Draws Wasted Heat From the Bottom of the Solar Panel, Cooling It to Make the Solar Panel More Efficient & Increase Power Output. This reduces the number of solar panels needed & reduces the overall system cost.

The Lower ECH^™ Is Attached To the Roof to Recover Attic Heat. It is Placed Beneath the Solar Panel for Shade, to Increase Thermoelectric Efficiency & Convert Otherwise Wasted Heat Into Electricity, Reducing Indoor Temperatures and cooling system loads.
