Partial shading is a problem that affects the performance of solar modules. Let's imagine a solar module that is composed of 16 solar cells, divided into 4 parallel strings that consist of 4 series-connected cells each. At a certain point, a leaf falls into the module, partially shading three cells: it shades 5% of the area of the bottom left one, 60% of the area of the bottom right one and 10% of the one in the top. A sketch of the module, with the leaf on it, can be seen below. Each cell, before the leaf shades some of them, has an open circuit voltage of 0.60 V and a short circuit current of 6.2 A. Assuming that all the interconnected cells have identical electrical characteristics, and that they experience the same temperature and insolation, what would be the approximate I-V curve that bests characterizes the PV module when it is shaded by the leaf?

Q.1) Assume that the control of a bottle filling system is performed with an 8051 microcontroller. • The start and stop of the conveyor is controlled by the P1.0 pin. • The bottles are moving on the conveyor and detected with a sensor. When they arrive at the filling place, they are detected with a logical "1" signal, otherwise they are detected with a "0" signal. • A valve connected to P1.1 turns on for 10 seconds to fill each bottle. • At every X bottles, the conveyor will stop for 8 minutes and then start again. The remaining time to restart in the waiting period is displayed in minutes on the 7-segment display. • Logic "1" is detected from P1.3 during the operation of the system. Logic '0' is detected from P1.3 at the end of the shift. • At the end of the shift, the number of the filled bottles will be determined and saved in a memory location as 2 bytes. Write the required program. (Crystal Frequency:12MHZ). NOTE: X number will be taken as the last 2 digits of 59
