The nominal power is the nameplate capacity of photovoltaic ( PV ) devices , such as solar cells , panels and systems , and is determined by measuring the electric current and voltage in a circuit , while varying the resistance under precisely defined conditions . These Standard Test Conditions ( STC ) are specified in standards such as IEC 61215 , IEC 61646 and UL 1703 ; specifically the light intensity is 1000 W/m2 , with a spectrum similar to sunlight hitting the earth 's surface at latitude 35°N in the summer ( airmass 1.5 ) , the temperature of the cells being 25 °C . The power is measured while varying the resistive load on the module between an open and closed circuit ( between maximum and minimum resistance ) . The highest power thus measured is the 'nominal ' power of the module in watts . This nominal power divided by the light power that falls on a given area of a photovoltaic device ( area × 1000 W/m2 ) defines its efficiency , the ratio of the device 's electrical output to the incident energy . The nominal power is important for designing an installation in order to correctly dimension its cabling and converters . If the available area is limited the solar cell efficiency and with it the nominal power per area ( e.g . kW/m2 ) is also relevant . For comparing modules , the price per nominal power ( e.g . $ /W ) is relevant . For a given installation 's physical orientation and location the expected annual production ( e.g . kWh ) per annual production assuming nominal power i.e .

Kern County is a county in the U.S. state of California . As of the 2010 census , the population was 839,631 . Its county seat is Bakersfield . Kern County comprises the Bakersfield , California , Metropolitan statistical area . The county spans the southern end of the Central Valley . Covering 8,161.42 square miles ( 21,138.0 km2 ) , it ranges west to the southern slope of the Coast Ranges , and east beyond the southern slope of the eastern Sierra Nevada into the Mojave Desert , at the city of Ridgecrest . Its northernmost city is Delano , and its southern reach expands just beyond Lebec to Grapevine , and the northern extremity of the parallel Antelope Valley . The county 's economy is heavily linked to agriculture and to petroleum extraction . There is also a strong aviation , space , and military presence , such as Edwards Air Force Base , the China Lake Naval Air Weapons Station , and the Mojave Air and Space Port . The county is one of the fastest-growing areas in the United States in terms of population growth , but suffers from significant water supply issues and poor air quality .

The Mojave Desert ( /moʊˈhɑːvi , mə-/ moh-HAH-vee , mə- ; Mohave : Hayikwiir Mat'aar ) is an arid rain-shadow desert and the driest desert in North America . It is in the North American Southwest , primarily within southeastern California and southern Nevada , and it occupies 47,877 sq mi ( 124,000 km2 ) . Small areas also extend into Utah and Arizona . Its boundaries are generally noted by the presence of Joshua trees , which are native only to the Mojave Desert and are considered an indicator species , and it is believed to support an additional 1,750 to 2,000 species of plants . The central part of the desert is sparsely populated , while its peripheries support large communities such as Las Vegas , Barstow , Lancaster , Palmdale , Victorville , and St. George . The Mojave Desert is bordered by the Great Basin Desert to its north and the Sonoran Desert to its south and east . Topographical boundaries include the Tehachapi Mountains and the Sierra Pelona Ridge to the west , the Sierra Nevada and the Inyo Mountains to the northwest , and the San Gabriel Mountains and San Bernardino Mountains to the south . The mountain boundaries are distinct because they are outlined by the two largest faults in California - the San Andreas and Garlock faults . The Mojave Desert displays typical basin and range topography . Higher elevations above 2,000 ft ( 610 m ) in the Mojave are commonly referred to as the High Desert ; however , Death Valley is the lowest elevation in North America at 280 ft ( 85 m ) below sea level and is one of the Mojave Desert 's harshest climates and best known places . Large parts of the Mojave Desert are often referred to as the high desert , in contrast to the low desert , the Sonoran Desert to the south . Most of the Mojave Desert is above 2,000 ft ( 610 m ) , with only Death Valley and the Colorado River basin in the east ( including the neighboring Las Vegas Valley ) being lower .

At full build-out , it will be one of the world 's largest PV solar farms with a capacity of about 800 MWp ( 600 MWAC ) . The project has been supported by several environmental groups , as the power station was built on low productivity farmland .
Imperial County is a county in the U.S. state of California . As of the 2010 census , the population was 174,528 . The county seat is El Centro . Established in 1907 from a division of San Diego County , it was the last county to be formed in California . Imperial County includes the El Centro , California Metropolitan Statistical Area . It is also part of the Southern California border region , the smallest but most economically diverse region in the state . It is located in the Imperial Valley , in the far southeast of California , bordering both Arizona and the Mexican state of Baja California . Although this region is a desert , with high temperatures and low average rainfall of 3 inches ( 76 mm ) per year , the economy is heavily based on agriculture due to irrigation , supplied wholly from the Colorado River via the All-American Canal . The Imperial Valley is divided between the United States and Mexico , and Imperial County is heavily influenced by Mexican culture . Approximately 80% of the county 's population is Hispanic , with the vast majority being of Mexican origin . The remainder of the population is predominantly non-Hispanic white as well as smaller African American , Native American and Asian minorities . In 2016 , Imperial County had the highest percentage of unemployed people of any county in the United States , at 23.5% .
