Advantages Of Connecting Solar Panels In Parallel

Wiring batteries and solar panel in series parallel configuration.

Advantages of connecting solar panels in parallel.

The connection of multiple solar panels in parallel arises from the need to reach certain current values at the output without changing the voltage. Unlike connecting in series connecting in parallel allows the voltage to stay the same but the current adds up. Wiring your solar panels in parallel results in more wires running from your solar panel system. Connecting your panels in parallel will increase the amps and keep the voltage the same.

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. Wiring solar panels in parallel causes the amperage to increase but the voltage remains the same. This allows to obtain the advantages of the series connection lower electrical losses and lower costs and the benefits of the parallel connection reliability. With parallel solar panels the positive terminal from one panel is connected to the positive terminal of another panel and the negative terminals of the two panels are connected together.

Typically solar panels of specific or matching current needs to be connected with each other in series. The amps of electrical current for each solar panel are summed together but the system voltage stays the same. You may think what is the purpose of this weird combination of series and parallel connection of both solar panels and batteries instead of simple series or parallel configuration well it depends on the system needs i e.

When an installer wires your solar panels in parallel each panel s wires are connected to a centralized wire leading from the roof. E g example if we connect 12 volts 8 amps 4 solar in. This is often used in 12v systems with multiple panels as wiring 12v panels in parallel allows you to keep your charging capabilities 12v. Should you connect a 3a solar panel to a 3 5a solar panel the all round current will probably be pulled down to 3a.

This kind of a lowering of current would of course cause a loss of power output and eventually loss in equipment efficiency. In fact it s the exact opposite of connecting in series. The calculation of solar panels voltage and ampere is opposite from series connection in series solar cell we plus the voltage and ampere will be same but in connecting solar panels in parallel connection our voltage v will be same and the current ampere will plus of all solar panels.
