This article explains the process of completing the system design in the Palmetto LightReach portal for the Home Efficiency Program (HEP). It provides an overview of the available residential system categories, along with descriptions and visuals for each type.
When you select a system category in the portal, typical equipment options will automatically populate in the Equipment and Materials section.
