Have you calculated solar added year by year to reach this conclusion? Sunny day electricity obviously becomes low cost, but I would be surprised if the drop is that quickly. This price drop will have some interesting opportunities for industry.
Nevada solar farm is being added at about 100MW / month, since THAT decision, Nevada solar approvals are trending to 200 MW/month. But as these are farm solar, they tend to single axis tracking and horizontal alignment, so not optimum for panel efficiency, but good for afternoon higher value solar.
Current market price for new solar farm in Nevada is
3.87 cents/kWh. Its not that hard to see further engineering 'mounting' improvements shave this figure down to 3 cents/kWh. Further panel improvements should get it below 3 cents/kWh.
The sunbelt states near California have plenty of mines, already serviced with good preexisting electrical infrastructure and land available for 'sun mining' Its dual use.
Hard rock mining tends to have a gold rush mentality. Its not hard to see a couple of dozen of
Nevada Copper Forms Strategic Alliance With NV Energy on Solar Development Opportunity | Energy and Mines going ahead in the next 4 years. In each of the sun belt mining states (particularly Arizona, Nevada, Utah, Colorado, New Mexico) kinda similar shale gas boom, but focuses on solar rich, dry air, elevated states.
I don't know if much of that solar production will go west, but it will block California solar production going east (which is the natural flow of solar power). Powerwall/powerpack batteries have a significant price advantage for single large installations, the solar farms should install their powerpacks at a significant discount to what SCTY can install powerwall units at.
Interesting times ahead, SCTY reminds me of BTU, too much debt spent in expensive legacy infrastructure, facing a wall of tsunami of cheap solar coming.

You need to remember to add about 7 or 8 cents per kWh for transmission and distribution. This will be included in TOU, even if solar takes wholesale prices below $30/MWh. Somebody's got to pay for the grid, right?
the transmission will be included in the TOU, but domestic solar users will still have to pay for distribution. Somebody will pay for the grid.
