A typical American household uses 26.5 kW-hour of electricity per day, and that electricity is mostly supplied by fossil fuels. If we wanted to instead power a house by solar panels, which receive on average 370 W/m2 from the Sun each day and are 15.7% efficient (fraction of solar energy converted into useable electrical energy), what area of solar panels is needed to power an average American home?

Solutions

Expert Solution

Total energy requirement for a typical American household is = 26.5 kW-hour per day

Energy receivd by solar panels per m2 per day is

Solar Energy converted into electrical energy per m2 per day is

To get the required area of solar panel we have to divide the required energy to the converted energy so

So the required Area of solar panels to power an average American home is 19.00786 m2

Consultants in a particular industry are currently paid $100 per hour and the typical work day lasts 10 hours. Demand for labour in that industry increases, resulting in the average hourly rate increasing to $150 per hour. However, a labour survey reveals that most consultants now work two fewer hours per day than they did prior to the rise in the price of their labour. A newspaper comments that this is at odds with the “law of supply”, such that...
