Figure 3: Series Parallel Connection effect on Current and Voltage

From the various plots above, it can be easily seen that series connected solar cell panel

produces less current compared to parallel connected solar cell panel but its voltage is also large

compared with the others. Figure 3 shows that the individual voltage of the panel adds up when

connected in series. In figure 5 also, it shows that the effect of changing the connections to

parallel makes the individual panel current to add up. From figure 7 on the other hand, both the

voltage and current change because series and parallel connection is combined. This is in accord

in the theory that series connection adds up its voltage while maintaining its current whereas

parallel connection adds up its current while maintaining its voltage.

The effect of changing the load resistance on voltage and current for the various cases

can be analyzed by this equation and the graph below:

V = I R (Ohms Law)

R = V / I or 1 / R = I / V

Can be written to,

I/V = 1 / R = slope of the line from the origin to a point in the I-V curve. (Figure 8)

Vertical line = infinite slope, this means that the load resistance is almost zero.

Horizontal line = 0 slope, this means that the load resistance is very large.

From the plot below (Figure 8), as the load resistance increases (slope decreases, line

slope from 1/R1 to 1/R2), the current slowly decreases and the voltage increases. But as the load

resistance increases more, a large current drop occurs with just a small increase in voltage until

it becomes zero at open circuit voltage. The net effect is as the load resistance increases, the

voltage increases and the current will decrease, just as stated in Ohms law.

Figure 4: Plot showing Load Resistance

The effect on shading of the composite array is when connected in series, the total current

could drop because the shaded cell is not producing current anymore and may become forward

biased if other unshaded modules are connected in parallel, resulting in heating of the cell. This can

lead to degradation of the cell performance and more worst to premature cell failure. But this can

be avoided by installing a bypass diode (shown in figure 9), which acts as a bypass for current when

it cant flow through a solar cell being shaded.

Figure 5: Solar Module with Bypass and Blocking Diodes (Source: Messenger, Vetre, PV Systems Engg)

The purpose of the blocking diode is to not to allow the passage of current in reverse

direction to the panel, in cases where there is no sun and a battery bank will have a greater voltage

compared to the panels, current could flow in reverse direction if blocking diode is not installed and

it will cause to heat up the panels.
