A rooftop solar panel measures 50cm × 150cm. The solar constant S = 1.37 9kW/m^2 , meaning that 1.37kJ of energy strikes every square meter of the Earth every second. Solar panels have a relatively low efficiency: e = 0.20, meaning that only 20% of the solar energy striking the cell can be converted to electrical energy. The solar array shown on the right consists of 25 panels, and the system operates at V = 20V.

a. Calculate the power of a single solar panel, P. The net power will be P = ePi where Pi is the energy/second incident on the panel.

b. What is the power Ptotal of the entire array of solar panels?

c. What is the resistance R of a single panel? Write your formula! Express your final numeric answer using the format R = ?value?. Include units!

d. How much current I flows through a single panel? Write your formula! Express your final numeric answer using the format I = ?value?. Include units!
