A homeowner in Allentown, PA installs a 60° south-facing solar collector that (on the average over the year) replaces 1 kW of electric heat (purchased from the public utility at $0.11 per kWh). The homeowner is considering adding a tracking mechanism to maintain perpendicular alignment of the collector with the solar insolation. If the payback period for the upgrade is expected to be five years, what should the homeowner be willing to pay for the tracking device?

If we wanted to supply all the electricity needs for New York City (NYC), with a popula- tion of about 10 million people, using photovoltaics technology, how much land area would we need? What other elements would be required for such an idea to work for NYC? How large of an investment would this involve, and how would the price of electricity in ¢ per kWeh have to increase in order to recover that investment in 10 years at an interest rate of 8%? For comparison, the average New Yorker paid 12¢/kWeh in 2002.

ter 2) i Saved versity campus has 200 classrooms and 400 faculty offices. The classrooms are equipped with 12 fluorescent tubes, each uming 110 W, including the electricity used by the ballasts. The faculty offices, on average, have half as many tubes. The us is open 240 days a year. The classrooms and faculty offices are not occupied for an average of 4 h a day, but the lights are on. If the unit cost of electricity is $0.175/kWh, determine how much the campus will save a year if the lights in the classrooms aculty offices are turned off during unoccupied periods. lights in the classrooms and faculty offices are turned off during unoccupied periods, the campus will save $ per yr. 2 (Chapte
An air-cooled window DX unit is used for space cooling. The unit has a capacity of 4.5 tons and has a SEER of 15. If the unit operates for 2204 hours during the summer, how many kWh of electricity will be used? Hint: In the U.S., the SEER is the ratio of cooling in British thermal units (BTUs) to the electrical energy consumed in watt-hours. You may need to convert the unit in this process.

Assume that the average solar insolation in Jamaica is 6500Wh/m² per day and its land area is 10,992 km². Consider that 3% of the land area could be covered by photovoltaic (PV) solar farms and 80% of the area of the solar farm is covered with PV modules with a conversion efficiency of 20%. In this case how much energy expressed in kWh/day could be produced using PV farms?

A home located in Texas, U.S. use 14000 kWh ofelectricity in 2021. The home is powered by a diesel generator, whichrequires 10000 liters fuel per year. The cost of fuel is $2 per liter. Theannual maintenance cost of the diesel generator is $4000, and the costof purchasing a new diesel generator is estimated at $10000. Theannual maintenance fee for wind turbine is estimated at 20% of its totalcost. The average wind speed is 6 m/s. Assume an effective lifetimefor diesel system is 5 years and for wind turbine is 10 years.a. Design the required size of wind turbine to cover 80% of theannual electricity usage.b. Estimate the cost of wind turbine designed in section c for aone-year operation.c. Considering a hybrid system including diesel – wind system,calculate the average penetration and define the penetrationclass.d. Considering the cost of diesel generator, would you recommendusing the above hybrid wind-diesel system? Assume the projectlife for 20 years. Please, describe.

Electricity generated from the system is a saving, as this amount of electricity is not going to be purchased from the utility company (or, if it’s a grid-connected system, electricity can be sold back to the utility company). How do you compute the annual dollar amount of the saving? Do the panels decline in efficiency each year?
