PRACTICALS

1. Correct the following circuit.

Ans: The solar PV panel generates DC voltage. There has to be a DC to AC convertor

before connecting the panel to the output. Put a DC-AC converter (An inverter)

between the Panel and the bulb.

2. Choose the right transformer used in an inverter.

Ans. (b) is right because inverter needs a step up transformer.

(a)

3. Demo of different types of CFLs and instructions todifferentiate between them.

(b)

4. Design A 600WP.SPV Power Pack:

Ans:

Module Size: 12V- 75Wp SPV 2 rows X 4 Nos. connected in parallel

Inverter: 800VA,

Battery: 24 V-2 X 12 V- 240AH

Distance Between SPV module & Inverter Room: 8mtrs.

Battery/ Cable Size: From the chart given. (select based on the current taken from the

module technical specifications and the distance given)

5. Maintenance and troubleshooting exercise. The system thatyou have designed, install it and execute all the maintenanceand troubleshooting exercises covering checking the modulecable connections, voltage drop across the cable, and as per thechapter given.
