This app icon concept was created for the PV Calculation mobile application. This app has numerous useful calculations for those who have to install photovoltaic systems. This concept was designed to enter the app icon contest. Unfortunately, I am not the winning person.

In this concept, I added the PV system. Thereby, we can identify that this application is related to the field of PV systems. I included a sun for the icon to more clearly identify rectangles as photovoltaic systems. Also, the application name helps identify the related field. Because of that, I did not include any text on the app icon. The number-1 design was colored using gradient colors.
The number-2 design was colored using flat colors.

Thank you.
