41. Wind capacity factors range from 20 40 % and solar capacity factors in Arizona are about 19 %. 42. The power production corresponds to a capacity factor of 76 %, which is relatively high for a hydroelectric facility. 43. Very favorable wind conditions in the state enable wind farms to achieve capacity factors in excess of 40 percent. 44. It was reported to have an annual capacity factor of 32 percent, not much different from current wind machines. 45. Note that capacity factor is not constrained by the Betz limit so capacities higher that 59.2 % are possible. 46. This means the ratio of average to peak output, or capacity factor , of this plant is around 22 %. 47. Solar photovoltaic array capacity factors are typically under 25 %, which is lower than many other industrial sources of electricity. 48. Capacity factor is a measure of the output of a power plant compared to the maximum output it could produce.49. Plants of various electric output and capacity factor may be assembled through use or varying numbers of molten salt modules. 50. Long term variations are due to the passage of relative standard deviation of the capacity factor to about 45 %.
