Question: Give two reasons why solar panels are almost never connected in series only?

Solar panels are almost never connected in series only for two main reasons:

1. The output current is limited by the weakest panel. When solar panels are connected in series, the current flowing through all of the panels is the same. This means that if one panel is shaded or damaged, it will reduce the output current of the entire string.
2. The voltage drop can be too high. The voltage drop across a solar panel increases as the current flowing through it increases. This means that if the current flowing through a series string of solar panels is too high, the voltage drop across the string can be significant. This can reduce the output power of the string and can also damage the panels.

To avoid these problems, solar panels are typically connected in a combination of series and parallel circuits. This allows the system to have a high voltage and current, while still ensuring that the output power is not limited by the weakest panel and that the voltage drop is not too high.

Here are some additional reasons why solar panels are not usually connected in series only:

• It can be difficult to match the output voltages of multiple solar panels.
• Connecting solar panels in series can increase the system's voltage to a level that is unsafe or beyond the capabilities of the inverter.
• Connecting solar panels in series can reduce the system's output power if one of the panels is shaded or damaged.

In general, it is best to consult with a solar installer to determine the best way to connect solar panels in your specific application.
