Hi,

So, they are 175W panels, so it would take 18 of 'em for a 3kW array? Which would cost $16,200. That is actually still a lot less than my friends paid for their more powerful array (4.5kW if I remember correctly?) -- they paid something like $36K installed.

The wiring diagram posted above (thanks!) says that you can have up to 16 of the 175W panels on a single circuit, and 14 of the 200watt variety.

I certainly hope these become much more common, and the price gets lower because of competition.
