How does a Grid-tied solar power. . Series connections are ideal for larger home solar systems (4kW+) and long distances to the inverter, but they're vulnerable to shading issues since one shaded panel affects the entire string. A String of PV Modules When N-number of PV modules are connected in series. The voltages are summed, but the current remains the same: Putting panels in series is desirable as it keeps the amperage low, and amperage is the key factor in cost of the wire. However, because every panel in a series. .
