Even at the rate of 0.08$/ kwh or may be 0.05$/kwh , it is not a bad deal for rooftop solar if you intend to use most of it personally.
That's exactly the goal here: make grid export uneconomical so you need to pair solar with a storage system that banks your afternoon excess into self-consumption once the sun goes down and the duck curve kicks into peak territory.
Everything is out of stock, earliest deliveries are weeks, sometimes months away depending on what you are looking for and suppliers that do still have some stock are playing favorites with their long term customers (which makes sense, from their perspective).
I ended up buying two NOS inverters and one brand new one that was a bit larger than what I really needed (three separate sets of panels, 42 in all). One of them arrived damaged and I had the option to return it for a full refund or take a 50% discount, I took the discount because I knew I wasn't going to be able to find another one.
Even second hand gear is priced through the roof.
