New Record Bid Set for World's Cheapest Solar, Undercutting Coal
One very important thing missing is that solar is not dispatchable. It does not serve the same purpose as coal and it is an apples to oranges comparison between solar and coal.Coal provides baseless power--coal plants are designed to run at a relatively steady level for more than 90% of the time. Reliable power is critical for things like server farms which draw power all the time. Solar cannot serve the same purpose without battery or other backup.At this time of year in places like California, solar doesn't help meet peak demand either.  http://content.caiso.com/green/renewrpt/20160503_DailyRenewa... Solar has a role, but comparing it to coal is misleading.
