Planning the solar array configuration will help you ensure the right voltage/current output for your PV system. In this section, we explain what these items are and their importance. Up to this point, you learned about the key concepts and planning aspects to consider before wiring solar panels. Now, in this section, we provide you with a step-by-step guide on how to.
Prepare Solar Panels for Wiring: Attach the MC4 connectors to the solar panel cables. Ensure a proper connection and use the crimping tool to secure them in place. Connect the Solar Panels: Begin the wiring process by connecting the positive terminal of one solar panel to the negative terminal of the next panel.
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.
Wiring solar panels in parallel is achieved by connecting the negative terminal for two or more modules, while doing the same thing with the positive terminals. The process is the following: Take the male MC4 plug (positive) of the modules and plug them into an MC4 combiner.
The steps to add solar connectors to PV wires are the following: Strip the wire. Place the connecting plate on it and use the crimping tool. Insert the lower components of the connector (terminal cover, strain reliever, and compression sleeve). Insert the upper components (safety foil, male/female MC4 connector housing, O-ring).
Connecting a solar panel to a battery is fairly simple. Start by connecting the positive wire from the solar panel to the positive terminal of the battery, then connect the negative wires from both components. Make sure that all connections are secure and in accordance with local wiring regulations.
Connecting PV modules in series and parallel are the two basic options, but you can also combine series and parallel wiring to create a hybrid solar panel array. Some solar panels have microinverters built-in, which impacts how you connect the modules together and to your balance of system. What Are They?

(b) Parallel connection. Photovoltaic modules must generally be connected in series in order to produce the voltage required to efficiently drive an inverter. However, if even a very small part of photovoltaic module (PV module) is prevented from receiving light, the generation power of the PV module is decreased disproportionately.
The following figure shows PV panels connected in series configuration. With this series connection, not only the voltage but also the power generated by the module also increases. To achieve this the negative terminal of one module is connected to the positive terminal of the other module.
So to begin with, Solar Cells are either connected in series or in parallel or combination of series-parallel to obtain the desired rating of voltage, current and power. Series connected solar cells have the same current flowing through them as they all are in the same path for current to flow.
In the figure shown above, six solar cells are connected in series. As we saw in our earlier post, here also we'll go with the assumption that the output voltage produced by an individual solar cell is 0.5 volts. Thus the combined output voltage in this case is the sum of the output voltages of the individual solar cells and is calculated as:
For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts. Related Post: How to Design and Install a Solar PV System? If 40 cells of 0.6 V are connected in series than the total voltage would be 0.6 V × 40 = 24 Volts.
