How to Wire Solar Panels in Series Parallel

In this video, we show you how to wire solar panels in a series-parallel configuration to get the best balance of voltage and current from your solar array. You'll learn step-by-step how to connect solar panels in series, then combine those series strings in parallel using MC4 branch connectors and optional inline fuses. This method keeps your voltages high enough for MPPT efficiency while keeping amperage manageable for wire sizing. Whether you're wiring 4 panels or scaling up to 16, the principles remain the same—and we break it all down simply so you can build with confidence.
