Actually solar and coal with CO2 capture are getting pretty close.

Coal causes 4,000 direct deaths per year and pollution from plants without pollution control measures cause tens of thousands of premature deaths annually.
Besides the radioactivity from coal- coal fires render and will continue to render more land uninhabitable than Chernobyl and Fukishima combined. Just one coal fire (burning for decades) has rendered as an area (700sqkm) as large as Fukishima uninhabitable. As a bonus- it pollutes a huge area with mercury and other pollutants.
I don't mean to give solar a pass (lots of rooftop deaths) (and we really don't know the down stream pollution effects or how much land will be rendered uninhabitable yet if we use a LOT of solar). My point is that solar is getting cheaper every day- batteries are getting better every day- and the cost of the two is getting fairly close (unless you want to burn raw brown coal with few to no pollution controls- then coal is half the price).
Personally- I've gotten a MUCH better bang for my buck from going to some CFL and mostly LED Bulbs (I esp. like the 900 lumen G7 3000K A19 factor bulbs. At $12.50ish they pay for themselves very quickly and as a bonus I've never had to replace one yet).

"As can be seen from the chart at the left, solar cell prices have come down by a factor of 100 over the last 35 years. (The reason for the small increase between 2005 and 2008 was because of a polysilicon shortage.) The 2013 average price is expected to be $.74."
"First Solar's stated goals are to be under $.55 in 2014 and to be about $.40 by 2017. "
When continuing maintenance costs are considered, solar is already less expensive than cheap coal after 19 years. Coal plants have a higher annual maintenance cost than solar. This is more relevant to municipal plants. A homeowner might be dead or move before the payoff is realized.
I own one solar panel as an experiment.
It generates a maximum of 178 watts (but an average of about 100 watts) between 10am and 6pm right now. I have to wipe it off about twice a month. It saves me about $2 per month averaged over the year but the largest savings are in the summer. I bought it 3 years ago and it will take 19.44 years to pay off (if it makes it- I think the micro inverter will break first). But it's made me aware of solar.
