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.
