How can one take advantage of cheap panels and have quality work done on the roof?
I've been looking at upgrading my rooftop solar in Australia, since we have had 5kW on the roof for close to 15 years now. Ill put away the pennies for a few more years and pull the trigger at a similar time to when we get our first EV / PHEV with V2G.
Why is your system so expensive? Storage?

Two of those is $27,200 minus installation and some solar panels to feed them (but the PW3 does have 3x 6.6kW solar MPPTs built-in unlike previous ones, so all you need to do is connect the panels directly to the PW3 and then the PW3 to your home).
Teach your kids how the blue collar trades are a better deal than a college degree, wait a decade or two, and contractor labor prices should be reasonable again.
