Insulation would probably be a better investment.
Indeed. On the roof: a second roof encapsulating the concrete one, that

The walls: they call it panel-w, styrofoam reinforced with steel strips

I have looked into solar panels: it would be several times the cost of
the house *and* you are up against the monopoly of the electricity company.
