I have updated the Android app to estimate Malaysia solar photovoltaic output. I included two more parameters, including module orientation and tilt angle. Now you have the option to face the module to North, East, South or West direction. Also, can see the output of the system at 3 different tilt angles.
You can download the app from http://www.tfesb.com/download.html or install from Google Play Store searching for "Malaysia Solar Calculator.
