Your whole argument will fall down because of this weird mistake:

> Let's say you can buy the panels at $300 for easy math

You'er assuming ~1$/1W for solar not installed, you're off by almost 5 order. I bought 330w panels ~2 years ago for 165$ each, which is exactly 0.5$/W and currently I can find 0.38-0.45$ / W for more modern panels (> 400w, Mono Perc... where 0.38 or less for price per pallet not containers even) and this is for home usage without subsidies and in the middle of the price hikes we're facing. For utility scale you can expect it to be 0.18-0.3$ / Watt (0.18 is a real price offered from some Chinese companies for wholesale without shipping prices), so all in all 10GW of solar panels will cost $1.8-3 Billion give or take, so your $9 Billion figure could make ~ 30-40 GW or even more given the expected price reduction and/or efficiency increase of the solar panels.
