Exercise 2: A solar panel has a peak power of 100 W when it receives a solar irradiance G= 1000 W.m It consists of photovoltaic cells connected both in series and in parallel. In each branch, the cells are associated in series, and the different branches are connected in parallel The voltage across the panel is 40V and each cell delivers a voltage of 0.5V and a current of 500 mA. 1. What is the number of cells in a branch? 2. What is the intensity of the current drawn by the panel? 3. Deduce the number of branches of the panel. 4. Determine the total number of cells in the panel. 5. Each cell is a 5 cm square. 5.1 What is the total area of the solar panel? 5.2 Calculate the solar panel energy efficiency
