Technical FAQs 4

How do you connect a solar panel?

Solar panel series connection diagram with five panels, showing positive to negative wiring. Connect the positive MC4 connector of Panel 1 to the negative MC4 of Panel 2. Repeat the process for additional panels. Connect the remaining open ends (Panel 1 negative and last panel positive) to your charge controller or inverter.

What is a series connection solar panel?

Definition: In a series connection, solar panels are linked end-to-end, where the positive terminal of one panel connects to the negative of the next. Effect on Voltage: Adds up (e.g., two 12V panels = 24V total). Effect on Current (Amps): Stays the same as a single panel. Best for increasing system voltage.

How do you connect a solar panel to a combiner box?
