Capacity factor. The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. [1] The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over ...
A solar power tower at Crescent Dunes Solar Energy Project concentrating light via 10,000 mirrored heliostats spanning thirteen million sq ft (1.21 km 2). The three towers of the Ivanpah Solar Power Facility Part of the 354 MW SEGS solar complex in northern San Bernardino County, California Bird's eye view of Khi Solar One, South Africa Concentrated solar power (CSP, also known as ...
Wind power has different characteristics, e.g. a higher capacity factor and about four times the 2015 electricity production of solar power. Compared with wind power, photovoltaic power production correlates well with power consumption for air-conditioning in warm countries.
The capacity factor for solar photovoltaic units is largely a function of climate and latitude and so varies significantly from state to state. The National Renewable Energy Laboratory has calculated that the highest statewide average solar voltaic capacity factors are in Arizona, New Mexico, and Nevada (each 26.3 percent), and the lowest is ...
Solar-cell efficiency. Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system.
Capacity credit. Capacity credit (CC, also capacity value[1] or de-rating factor[2]) is the fraction of the installed capacity of a power plant which can be relied upon at a given time (typically during system stress), [3] frequently expressed as a percentage of the nameplate capacity. A conventional (dispatchable) power plant can typically ...
Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industry, and in the residential and commercial sectors. Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-, or high-temperature collectors.
Capacity utilization or capacity utilisation is the extent to which a firm or nation employs its installed productive capacity (maximum output of a firm or nation).
