how about some numbers,

how many kW does your system produce peak?
how many kWh do you use a day?
how much did it cost you to install?
what subsidies did you get?
how long will it take you to break even?

Article in local paper about installing system in a church.
They said half the cost of $738,000 was subsidized by a state grant
and it would pay for itself in 10 years.

There was a similar article about a home owner doing it a few years
ago. Can't remember subsidy but they said it would take 30 years to
recoup.

if it wasn't for grants/subsidies, they would never pay for themselves as
the payback time is longer than the equipment lifetime.

Particularly in an area with the possibility of hail.

that said, the payback for my system is about 4.5 years at current
electrical rates; there is a planned increase in rates for later this year,
and we've had one every 2 years or so, so the payback time would get a bit
shorter.

As long as they don't drop the subsidies, perhaps. *You're still relying on

Small generating site distributed round the grid help matters by
reducing grid loading.

No, it *hurts* by reducing control. *If even a large fraction of the people
did it, the net cash flow would be out; not good for the infrastructure,
either.

The grid tie inverters are required to have an "anti-islanding"
feature..

Whats the differnence beween 3Kw into the system and 3Kw out? Both
pose exactly the same control problems.

You really are clueless. The sun is pretty well synchronized across a wide
area. Loads aren't.
