Question
Chapter 10, Problem 31E
Interpretation Introduction
Interpretation:
The area of the PV cell required to build a charging station is to be calculated.
Concept Introduction:
Power input on a PV cell is the total active area of the PV cell multiplied by the solar power.
The percent of the input power that is converted into output power by a PV cell is called its efficiency.
Percent efficiency of a PV cell is 100 multiplied by the ratio of power out and power in.
The expression is as follows:

A number of companies currently lease solar panels to homeowners to offset the home’s energy use. The total energy production of a certain residential solar system in suburban Maryland was 7581.62 kWh over the last calendar year. What mass of carbon dioxide did this solar system keep out of the atmosphere during that time, assuming that the energy consumed by this home would otherwise have been supplied solely by coal-burning power plants (note that this isn’t a great assumption, as Maryland also has a nuclear power plant, solar and wind farms, and Montgomery County incinerates waste to generate electricity)? Keep in mind that power plants are inefficient, and are able to convert on average 33% of the heat generated by the combustion of coal into electricity. Assume that coal can be approximated as C(s) (again, not a great assumption, but sufficient for this problem). Use the following data to find the heat of combustion of coal:
2 C(s) + O2(g) ----> 2 CO(g).…

- The best solar panels currently available are about 15% efficient in converting sunlight to electricity. A typical home will use about 40. kWh of electricity per day (1 kWh = 1 kilowatt hour; 1kW = 1000 J/s). Assuming 8.0 hours of useful sunlight per day, calculate the minimum solar panel surface area necessary to provide all of a typical homes electricity.

A technique that power plants can adopt to keep most of the CO2 from entering the air is called CO2 capture and storage (CCS). If the incremental cost of the sequestration process is $0.019 per kilowatt-hour, what is the present worth of the extra cost over a 3-year period to a manufacturing plant that uses 100,000 kWh of power per month?
