I don't have stats for subsidy-less coal, but I'll point you to [1], which gives the unsubsidized installed price of grid-level solar (defined as >500kW) power as being about $2.30/Wdc in 2015. Page 14 has a summary graph of this parameter since 1998.

The report gives pre-incentive prices for residential (<10kW) and non-residential (<500kW) as well.
