2.2 Name THREE major components of a PV installation and discuss the function of each component. (6 2.3 You have installed an alternative supply at your plant that you want to connect to the supplier's grid. What do you need to do and determine before you may connect it to the grid? (3)

a) A solar installation is required to produce 440V AC for domestic use. However, there is not a single solar cell that can produce this amount of voltage on its own. Evaluate the solar panel installation by identifying the limitations of a PV cell. Explain its operation and assembly details for organizing the Solar PV cell, PV module, string connection, PV panel, and connecting them together in parallel and series to achieve a practically usable voltage required for a commercial installation. b) Explain how the DC voltage is converted to AC voltage in a typical Solar PV installation by evaluating the detailed design of the inverter system. c) Given that a Solar panel containing 100 Solar cells is arranged as a single string that can produce 50V DC and a current of 10 Amps, design a layout with appropriate connections to provide 5 kW power to a house. You may select a suitable inverter system and illustrate its connections using a diagram.
