The same study suggests that the cost of solar energy is extremely scale dependent ranging from roughly $180/MWh for residential scale installations to about $55/MWh for "Utility" scale installations.
The fine print in the study says, "...does not take into account... reliability or intermittency related considerations (e.g.,transmission and back-up generation costs associated with certain Alternative Energy technologies)"

Consider the incandescent lighting in the cooler of a convenience store during the month of August. Most of the power going to the bulb generates heat, not light. That wasted energy must then be extracted from the cooler and pumped "up hill" to an air-to-air heat exchanger that is well above 90 degrees F. In a similar way, think about cooking inside of an air conditioned space in the middle of summer. That microwave and outside barbecue look mighty good to the utility.
