6 Frequently Asked Questions about “Multiple solar panel voltages are inconsistent”

How to calculate solar power if a solar panel is mismatched?

To calculate our expected power, we multiply voltage times current. However, since these are mismatched solar panels, we are limited by the lowest current, which is the Thunderbolt (4.4A). So, wiring different-sized solar panels in series is not an ideal solution. But, what is a better way? Let's calculate our expected power with parallel wiring.

What happens if you connect solar panels in parallel?

When you connect solar panels in parallel, the total output voltage of the solar array is the same as the voltage of a single panel, while the total output current is a sum of the currents passing through each panel. The latter is only valid provided that the panels connected are of the same type and power rating.

Can I connect different solar panels in a solar array?

Connect only in series panels of the different brands and of the same current. Connect in parallel panels of different brands and of the same voltage. Connecting different solar panels in a solar array is not recommended since either the voltage or the current might get reduced.

What are the characteristics of a solar panel?

These are current and voltage. As previously mentioned, when we connect solar panels in series, the voltage gets added up. When we wire multiple solar panels in parallel, the current gets added up. Now, how can we use these characteristics to our advantage when we are mixing solar panels?

Why do I need to wire my solar panels in series?

When your panels have the same current but different voltage, you need to wire your panels in series. This is because the voltage gets added up, while the current stays the same. You can see this in the following diagram. When your panels have the same voltage but different current, you need to wire in parallel.

How does wiring solar panels in parallel affect volts & amps?

Wiring solar panels in series adds their voltages while their amperages stay the same. Wiring solar panels in parallel adds their amperages while their voltages stay the same. How Does Wiring Solar Panels In Parallel Affect it's Volts & Amps?
