Study of the voltage and current of the solar cells in series and parallel Combinations using Solar Energy Trainer NV605.

                                    Experiment-6B

Aim: Study of the voltage and current of the solar cells in series and parallel Combinations

Procedure:


1. Take the Solar Energy Trainer NV6005 along with Solar Panel.

2. Place the Solar Panel in the stand and adjust the panel at an angle of about 45º
with the ground. Direct the sunlight straight at the solar panel (angle of 90º).
Note: If sunlight is not properly available then any source of light like a lamp can
be used.

3. With the DB15 connector connect the Solar Energy Trainer NV6005 with the
Solar Panel. Then wait for 1 minute to avoid errors due to temperature
fluctuations.

Series combination of cells:


4. With the patch cords, connect outputs of all cells one by one in series such that
the positive terminal of one connected to the negative terminal of the other as
shown in figure 21.

5. Connect the positive and negative terminal of the series combination across the
voltmeter as shown in figure 22.
