As this is not mentioned, is it possible to extend the system by collecting rainwater falling on solar panels ?

Talking about apps I would recommend MosaLingua (digiSchool), it helps me for English and Spanish.

It’s mainly design to learn vocabulary (spaced repetition), the app is free, only class/courses may required a subscription.
