Set Up Your Panels Lay out the panels evenly, and line them up to maximize your available space. Wire from Positive to Negative Connect your wires from the positive pole of one panel to the negative pole of the next. Connect the Array to Your Inverter .
Wiring solar panels in series in 5 stepsStep 1: Prepare the equipment Put solar panels where you want them. Step 2: Connect positive and negative terminals Each panel has a positive and a negative cable coming out of its junction box. Step 3: Connect the open terminals . Step 4: Secure and protect the wiring . Step 5: Test the system .
To connect solar panels of the same model and rated power in series, wire the positive terminal to the negative terminal of each panel in the array.
The series connection is done by wiring the positive terminal of each panel to the negative terminal of the next panel (a connection similar to the ones of the Christmas lights) until the final pan.

6 FAQs about [How to connect solar panels in series]
Why do solar panels need to be connected in series?
Putting panels in series makes it so the voltage of the array increases. This is important because a solar power system needs to operate at a certain voltage for the inverter to work properly. So, you connect your solar panels in series to meet the operating voltage window requirements of your inverter.
How to wire solar panels in series?
Wiring solar panels in series requires connecting the positive terminal of a module to the negative of the next one, increasing the voltage. To do this, follow the next steps: Connect the female MC4 plug (negative) to the male MC4 plug (positive). Repeat steps 1 and 2 for the rest of the string.
How to wire solar panels together?
Wiring solar panels together can be done with pre-installed wires at the modules, but extending the wiring to the inverter or service panel requires selecting the right wire. For rooftop PV installations, you can use the PV wire, known in Europe as TUV PV Wire or EN 50618 solar cable standard.
How do solar panels connect in parallel?
This connection wires solar panels in series by connecting positive to negative terminals to increase voltage and connects these strings in parallel. All solar panel strings connected in parallel have to feature the same voltage, and they also have to comply with the NEC 690.7, NEC 690.8 (A) (1), and NEC 690.8 (A) (2).
How are solar panels wired?
The way in which solar panels are wired determines how the system performs and what inverter the system can be paired with. When solar panels are wired in series, the positive terminal of one solar module is connected to the negative terminal of another, which increases the voltage of the solar system.
What if two solar panels are connected in series?
So, if you connect two solar panels with a rated voltage of 40 volts and a rated amperage of 5 amps in series, the voltage of the series would be 80 volts, while the amperage would remain at 5 amps. Putting panels in series makes it so the voltage of the array increases.
