The install costs arnt that insignificant either.
Around 30% of the total costs in Australia.
Id be interested in what install costs are in other countries.

Absolutely zero idea. Why anyone would want solar PV in a country like
mine that averages around 850 kWh p.a. of sunshine beats me. Might give
you about 350Wh daily with a 1 m2 panel. I could barely run my CFL
lighting on that, and in winter I'd have to live in the dark.

You should REALLY look at going to 24 Vdc, if your planning on getting
anywhere near 2K watts output.  Trace makes the DR2424 and you can use
the same panels connected in series for 24 Vdc Charging.  Just figure
out how many AMPS 2Kw is at 12 Vdc, and at 24 Vdc, and you will
understand the problem.  Batteries don't like that kind of Amp draw.
