Electronic calculator?

[BIGFOOT]

Any recommendations on a PV calculator app for Android for electrical calculations and panel positions at your location?

For estimated monthly average solar irradiance and panel angles I like this calculator http://www.solarelectricityhandbook.com/solar-irradiance.html

Not sure about an app, but in my signature block there is a online off-grid calculator. You can change the direction and tilt of the panel to see about outputs.
