This guide covers series vs parallel fundamentals, string sizing math with worked examples, NEC 690. 7 temperature derating, mismatch rules, shade-aware strategies, DC wiring requirements, and how solar design software handles all of this automatically.

Most battery systems support 2-4 batteries connected in parallel for residential applications. Consider an off-grid motorhome with a daily consumption of 10kWh: A 48V, 100Ah (5kWh) battery requires two parallel banks for two days' backup.

In this tutorial, I'll show you how to wire solar panels in series and how to wire them in parallel. Once we've got that covered, I'll also explain the difference between these two configurations in Voltage (Volts) and Current (Amps) and provide a real-life example.
