1.Question 1

If a 12 V module has 36 individual cells, then how many volts is a module with 54 cells?

6 V

18 V

24 V

36 V

Correct

That is correct

The voltage of a series connection of solar cells is the sum of the voltages from each individual cell.

1 / 1 point

2.Question 2

Select the circuit in which the solar cells are connected in parallel.

Circuit A

Circuit B

Correct

That is correct

Components connected in series are connected along a single path, while components connected in parallel are connected along multiple paths.

1 / 1 point

3.Question 3

Series connection

Two solar cells (solar cell A and B) are connected in series. The solar cells have the following parameters.

Solar Cell A

• VOC = 0.5 V
• ISC = 1.2 A

Solar Cell B

• VOC = 0.6 V
• ISC = 1.0 A

What is the open circuit voltage and short circuit current of the series connection of solar cell A and B?

VOC = 1.1 V and ISC = 1.0 A

VOC = 0.5 V and ISC = 2.2 A

VOC = 0.6 V and ISC = 1.0 A

VOC = 0.6 V and ISC = 1.2 A

If you find this answer, then comment!!!

4.Question 4

What is the role of a bypass diode?

Reduce current

Limit effects of shading

Increase current

Prevent reverse current

Correct

That is correct

You can read more about bypass diodes here. And maybe revisit the virtual instrumentfeaturing bypass diodes.
