QUESTION

# A customer's house in Binghamton, NY uses 5750 kWh per year. Full-sun-hours per year in Binghamton =1496 System efficiency = 0.75 The following final graded quiz will ask you to use these inputs to calculate the system size and cost. Here is one formula to get you started: Solar electric size in kilowatts (kW) = yearly electric usage in kWh divided by (full-sun-hours multiplied by system efficiency) In formula form: PV size in kW = load in kWh ÷ (Full-sun-hours per year x system efficiency)(i)-Based on the information provided in the Final Graded Quiz Specs reading, if we use 327 WDC (0.327 kW) PV panels, how many of them will you need? Round up to the nearest whole number.(ii) Using your answer from Question 1, if the cost is $3.25 per Watt, what does the whole system cost?(iii)-The New York solar grant is$0.35/Watt. Using your prior answers, what is the total grant the customer will receive? Round your answer to the nearest dollar.(iV)-The Federal tax credit is 26% of the (after-New York grant) system cost. Using your previous responses, how much is the Federal tax credit? Round up to the nearest dollar.
