Photovoltaic systems (35 marks)
You have been provided with the following components of a solar home system:
▪ A 80W PV panel
▪ 1 charge controller: 10A-12V
▪ 1 battery: 12V, 125Ah
▪ 1 inverter: 12V DC – 220V AC
▪ A 220V lamp.
Work required
1.1 Position all the components of the photovoltaic system
1.2 Wire the solar components to the charge controller
1.3 Connect the incandescent lamp to the solar system
1.4 The lamp must come ON. If the system does not work correctly at the first trial, the candidate is given two
more chances to make it work correctly. The candidate loses 5mks after each unsuccessful trial. If after
three trials the circuit does not work, it is the duty of the examiners to make it work so that the candidate
can continue with the rest of the examination.
