j'aimerai svp un dialogue entre un vendeur de panneau voltaïque et un acheteur de panneau et il fodrait que le vendre conseille sur les prix et tout le tout zn

You have the choice between two models, the cheap one and the expensive one.
The cheap one is great for monthly use, not for a daily use. It costs only 400$
On the other hand, the expensive one, is great for a daily use. It can't handle a power of 20000 watts. This one costs 1300$
