User Interface Design for Solar Panel Monitoring System on Android Smartphones Using User-Centered Design Method

In 1970, the world overcame the special energy crisis of petroleum. However, since then many people have used solar energy as an alternative energy source. As an alternative source, the use of solar power systems can easily spread throughout the world because of its low maintenance and ease of deployment. But the use of solar cells that have been integrated with the user's will is not widely available, for example, the use of solar cells that are integrated with smartphones. In connection with this, it will be very easy if the process of monitoring or monitoring the use of solar panel power and the application of smart home technology is done with a computerized system, for example by using an Android-based application. When interacting with the Solar Panel Monitoring Application on Android Smartphones the user must get the same comfort by his experience using other systems. This writing aims to design a Solar Panel Monitoring Application system on android smartphones using the User-Centered Design (UCD) method. The user as the center of the design system development process is called the User-Centered Design (UCD) design philosophy. From the 8 parameters of usability goals and user experience, the average percentage stage is 81%. It means that the design of the system is good.
