by IntelFreePress Question by : A silicon solar cell array works at an efficiency of 14% in sunlight. If the solar array covers an area of 5 m? help frndzz.. Best answer: Answer by MariaUse the equation: efficiency = P / E * A, where P is power, E is irradiance, and A is area. Rearrange the equation to give P = efficiency [...] The Alliance to Save Energy’s Monique O’Grady explains how ENERGY STAR-rated homes are the most energy-efficient models around. Compared to standard homes, ENERGY STAR-rated homes lower energy bills by between 0-0 dollars per year. Learn more about energy efficiency at www.ase.org Energy Star’s Katharine Kaplan talks about how Energy Star ratings work. Government and industry come together to set Energy Star ratings. These Energy Star ratings may slow global warming by making appliances more energy efficient. Learn how Energy Star ratings work. Question by DeeJay: How can we increase the efficiency of solar cells? Best answer: Answer by Steve SEvery solar cell has a maximum theoretical efficiency. It is a property of that cell, and no matter the conditions it cannot be any higher. The most efficient one, to date, is ~35%. Factoring in material and system limitations, the maximum efficiency we have attained is ~30%. Unless we find a new combination of materials for a [...] Question by muhlange: What is the best current efficiency of silicon solar cells? http://www.iea-pvps.org/pv/materials.htm Forgot to add this. Mentions about conversion efficiency of silicon based solar cells. IMHO a bit outdated, since it was written in 2002. Best answer: Answer by Robert Thttp://www.gizmag.com/go/6563/picture/29635/ The 40% is not Si, but it is multi-junction, to capture a broader frequency spectrum of sunlight. The picture in the link is hard to read, but I believe there is [...] What’s for dinner? ENERGY SAVING BULBS DON’T WORK WITH SOME DEVICES & EMIT HIGH UV RADIATION LEVELS |
