Solar Panels Wired in Combination
Series/parallel combination wiring requires that at least two sets (or strings) of panels wired in series are connected in parallel.
When panels are connected in combination:
• Voltage accumulates (adds) for each panel in a single series circuit, but does not accumulate for additional strings wired in parallel.
• Wattage accumulates (adds) for each panel in a single series string AND each string in parallel circuit (all panels in the array
contribute additively to the total wattage).
• Current (Amps) remains the same for single panels in a series, but accumulates (adds) for additional strings connected in parallel.
