Small solar installers find Aurora and pro design tools too expensive and limited and hunt for cheaper proposal software

Solar installers and sales reps need PV design plus proposal software to size systems, model shading, and generate customer proposals. The category leader Aurora is widely called too expensive for small companies (estimated 2640 to 6000 dollars per user per year) and is missing electrical detail, pushing installers to free tools like OpenSolar. The OpenSolar Android app has 103 ratings and creator walkthroughs on the cost problem draw thousands of views from installers comparing tools. Gap is a low cost pay-as-you-go design plus proposal plus permit-ready output tool for small installers, not the enterprise priced incumbent.
