A module of 96 ideal solar cells (typical for a Sunpower module) placed in series (Rseries = 0, Rparallel = 0) is attached to a resistive load. The light incident on the cells varies sinuosoidally throughout the period between 6 am and 6 pm, peaking at noon and zero at 6 am and 6 pm. At noon, each individual cell has a short circuit current and open circuit voltage of 1;c=6.23 A and Voc=0.707 V. To account for this we use 1.(t) = 6.23 cos((12 - 1)/12) A. where 6 <15 18 hours. Further we take 1, = 1.06 x 10-11 A, A resistive load is chosen so that the solar cell operates at maximum power at noon. For this configuration we find R_ = 9.9412. The resistor is not changed as the light varies. Calculate the power throughout the day by summing the power provided at each hour be- tween 6 am and 6 pm. There are two configurations to examine. a) The solar cell is directly connected to R, and the operating point is determined by the load line for R. Find the sum of the power produced at each hour.
b) Using power electronics the operating point is set at the maximum power point. Equiv- alently, remove the load and find the sum of the powers at each MPPT throughout the day.
c) What is the percent difference between the two totals.
