Compare the costs of generating electricity using solar energy in different parts of the united states. a. (5 points) let us consider a simple 25.m2 rooftop installation of crystalline-silicon (c-si) pv modules. now remember that pv modules are rated to receive 1kw/m2 of solar radiation. assuming peak solar irradiation of 1 kw/m22, what would the peak output of this system be (in kw) if the modules are 16% efficient? b. (10 points) compute the annualized cost for this type of pv module (in $/year), assuming for simplicity that operating costs can be ignored. assume a 6.0% discount rate and 25-year lifetime. initial cost unit value ($) module cost $/watt 2.20 permitting and inspection cost $/watt 0.25 installation labor cost $/watt 0.90 inverter cost $/watt 0.50 c. (10 points) now, consider how much electricity our pv system from part (a) will actually be able to generate in different cities based on variation in insolation levels. calculate the annual electricity generated by our pv system and the levelized cost of solar energy in san francisco, ca (2,500 kwh/m2-year); new york city, ny (1,600 kwh/m2-year); detroit, mi(1,500 kwh/m2-year); and flagstaff, az(3,200 kwh/m2-year). d. (5 points) calculate the simple payback period for your solar system in san francisco. assume that your household consumes 15,000kwh/year.
