connect solar panels in series or parallel

With the cost of solar energy production on the steady decline, more and more homeowners are looking for ways to maximize their savings by installing solar panels. Two of the most important considerations when it comes to solar panel installation are whether to connect the panels in series or in parallel.

Connecting solar panels in series means connecting the positive terminal of one panel to the negative terminal of the next panel, so that the energy current flows from one to the other. This configuration is beneficial for homes with high energy needs, as it increases the power output of the system. The downside is that if one panel malfunctions or is shaded, it can affect the entire system.

The alternative is to connect the solar panels in parallel. Instead of connecting the positive and negative terminals of each panel, the positive terminals are connected together and the negative terminals are connected together. This helps protect against short-circuits, as any malfunctioning panel only drops out of the circuit, instead of dragging the rest of the system down. Although this configuration does not increase the power of the system, it does provide reliable power to homes with an average energy consumption.

Ultimately, the decision between connecting the solar panels in series or parallel depends on individual needs. If a homeowner desires increased power output, the series configuration is a viable solution. However, if reliability is the priority, then connecting the panels in parallel is the way to go. It’s wise to consult an experienced solar installer for advice on the best way to configure the system.
