I guess the only thing you can say is....good start. Below is an idea of how much land is required to generate the equalivent power of a normal sized power plant.
Theres around 800MW of total Nameplate Capacity for all Solar Power in the US, around as much as for one medium sized coal fired plant. If all those Solar Plants produced at their maximum, which by the way means that a way has to be found to make the Sun shine for all night as well as all day, then they could deliver around 600Million KWH of power. They actually delivered 143 million KWH of power to the grids they are connected to. This gives them a power delivery efficiency of 23.8%, effectively meaning they too can only deliver their power for around 6 hours of each day. The rolling 6 month percentage only comes in at 13.1%, or around 3 hours a day.
As a Reliability Coordinator, I would rather have solar than Wind Generators.
