My expectation would be to increase the 8-9months for operation of the solar facility to 2+ years. Set up,permitting, training, design reviews etc all take considerable time. Remember to also account for supply chain set up - chiplead time seems to be quite long. I also assume they will use a pull system which takes time to set up.
My point being I think the bar is far too high at 8-9 months. It will take time.
