SunCost

Windows desktop app that estimates rooftop solar potential, electricity savings, and payback time from the solar radiation data of the user's location.

SunCost preview

Detail project

Indonesia receives some of the highest solar radiation in the world, yet rooftop solar adoption stays low because people cannot tell how much their roof would produce or when the investment pays back.

Users enter their location, roof area, orientation, and tilt. SunCost combines weather API radiation data with panel specs and electricity tariffs to show energy output, savings, and payback period.

Led the team as software architect, designing the class structure and the split between views, models, and services in a C# WPF app with a local SQLite database.
