Wiring Different Solar Panels Together

Another option is to take multiple solar panels and wire them together to equal the same output as the other mismatched panel.

Wiring different solar panels together.

Series wiring sixteen panel solar system watts since we connected 16 panels together in series this solar system will output 1008w of power per hour maximum under optimal sunlight conditions. Wiring your solar panels in parallel results in more wires running from your solar panel system. This is the same wattage as the previous sixteen panel system and thus has a great amount of power. Connecting solar panels in parallel is just the opposite of series connection and is used to increase the total output current of the array and hence the total output power while keeping the same voltage.

Firstly lets take a look at connecting solar panels in series. The white line is the negative connection all 3 panel negative wires are just simply tied together and to the wire that runs back to the negative connection on the charge controller. When an installer wires your solar panels in parallel each panel s wires are connected to a centralized wire leading from the roof. Wiring solar pv panels in parallel the next basic type of connecting solar panels is in parallel.

In the solar industry. The amps of electrical current for each solar panel are summed together but the system voltage stays the same. For instance in the demo below we have a 100w 24v panel and some 50w 12v panels. What we can do is wire the two 12v panels in series plus to minus and then we can wire it in parallel with the 24v panel.

The red line is the positive connection to the panels. The connection of multiple solar panels in parallel arises from the need to reach certain current values at the output without changing the voltage. The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector. To have a functional solar pv system you need to wire the panels together to create an electrical circuit through which current will flow and you also need to wire the panels to the inverter that will convert the dc power produced by the panels to ac power that can be used in your home and sent to the grid.

Solar panels are usually connected in series to obtain higher output voltage. In fact by wiring several solar panels in series we increase the voltage keeping the same current while wiring them in parallel we increase the current keeping the same voltage. Both have their own purpose and applications and both have different outcomes when hooking up solar panels of different wattage together.
