One thought - the model seems vaguely similar to a pension annuity in that
you surrender some capital and then get a guaranteed index linked income.

Only a very shaky analogy because apart from anything else it assumes you
will stay in your current residence for the rest of your life (or at least
the 20+ years predicted life of the array).

As well as political uncertainty (will they drastically alter the
payments for existing installations?), it's the "20+" and "predicted"
that are the real issue. If you believe them, then fine. Otherwise,
how much do you need to allow for maintenance and repairs?
