You are probably correct. So the thing to do to refine the analysis would be to select prorata, then generate the five types of consumers as per my previous post. Would you be up for doing that?
This is because how much money you save does not only depend from whether you are copropriétaire habitant or not, but also on the size of your unit.
Financially, you are right. But economically, the advantage of even making that investment comes indeed from the saving in electricity bills. Additionally, an energy community is not made only of producers, but of producers and consumers. The role of consumers is as important as that of the producers in enabling the economies in question.
On top of that, consider someone who is both an investor and an inhabitant. That person’s investment will indeed be made more attractive by the reduction in their private energy bill. In a way, as an investor-inhabitant you do not need to be compensated so much for the loan you give to Torpedo, because you get some advantages in the form of a reduced energy bill. Even if Torpedo pays back te loan in five years, the investor-inhabitant has more money than they would have had without the investment by the end of the fourth year.
