Solar cells (the figure) can produce about 40 W of electricity per square meter of surface area if directly facing the Sun. (Figure 1) Part A How large an area is required to supply the needs of a house that requires 22 kWh/day? Assume there are 9 hours of sunlight per day.

Part B Would this fit on the roof of an average house? Assume a small house with 1000 ft2 of floor space, and a roof tilted at 30∘.

1. Solar cells (the figure) can produce about 40 W of electricity per square meter of surface area if directly facing the Sun. How large an area is required to supply the needs of a house that requires 21 kWh/day? Assume there are 9 hours of sunlight per day. Express your answer to two significant figures and include the appropriate units. 2. Energy may be stored by pumping water to a high reservoir when demand is low and then releasing...

A model cost/benefit analysis of solar power. The main ingredients of this analysis are the power used (required) and the power delivered. For a simple model we want to use broader averages. Used: An American home has an average power use of 1.2 kW. That means that considering all of the daily variation, the difference between night and day and the seasons, etc., the average at any given second is 1.2 kJ per sec = 1.2 kW. Delivered: The home...

Part C: The Earth’s atmosphere can be considered to be a heat engine, in the Carrot (thermodynamic) sense. The temperature at top of the upper atmosphere is that necessary to radiate infrared energy back into space so to balance that gained from the sun. The surface is heated by the sun and insulated by the atmosphere (the greenhouse effect) so it’s warmer. 1) What is the efficiency of this heat engine if the air at Earth’s surface is 288 K...

In this exercise we will consider two coal-fired power plants and a solar thermal plant, in order to compare their power densities, i.e., their power output vs. the amount of land they occupy. This method of comparison of diverse forms of renewable and non-renewable energy systems was pioneered by Vaclav Smil of the University of Manitoba in Canada. The first coal plant is highly efficient and is optimally located, next to a mine that supplies high-quality coal from a thick...
