I wonder how much energy has gone into constructing the damn things,
installing them and building an electrical distribution system? What is
the payback period? without the subsidy of course.

what is one over a negative quantity? greater than infinity...

There is no payback period, with an MTBF of about 2 months and a
lifetime of less than 20 years, the ruddy things will always be a net
drain on the economy.
