Two panels in series add their voltages; strings in parallel add their currents. A panel's open-circuit voltage (Voc) rises on cold, bright mornings, so each arrangement below is checked with the panel's own temperature coefficient, or -0.35% per °C where the maker publishes none, at -10 °C (14 °F). Strings in parallel are kept within the input's current figure; a single string that could give more is held back by the input itself.

5 of the 18 panels fit, fastest refill first. Each uses every input that can take it; the hours are full sun, from empty.

"Full sun to refill" is the ideal floor: the station taking its input limit every hour. Panels rarely deliver their rating, so the 70% column is closer to a good day, and a usable day holds four to six hours of full sun in most of the US. Panels whose maker does not name an MC4 plug are counted one to an input, since they link to others only through the maker's own adapters.
Cables between panel and station
Jackery SolarSaga 200W: DC8020 on the panel and 8 mm on the station, so you need a DC8020-to-8 mm solar cable. Its cable: 3 meters.
Jackery SolarSaga 100 Prime: Anderson on the panel and 8 mm on the station, so you need an Anderson-to-8 mm solar cable. Its cable: 9.58 feet.
What a day of sun puts back
Watt-hours back in a day, at a 70% panel yield and the station's input limit. Winter in the northern US gives about 3 hours of full sun, a clear summer day in the Southwest 6 or more.

Where the solar limits come from
Goal Zero product page: "8 mm Low Voltage Input: 200W Max (12.3-28 V, up to 10A)" · "Solar (200 W Max): 2 hrs." · "200W (Nomad/Boulder 200): 2 hrs. (RequiresHPP to 8mm connector)"
Goal Zero user manual (PDF): "IMPORTANT NOTE: When solar charging your power station, take note of the voltages of the solar panels and do not exceed 30 V. Individual solar panels, or solar panels chained in series in excess of 30 V cannot be used with the Goal Zero Yeti and can cause serious damage to the unit." · "Your Goal Zero Yeti has one 8mm charging port located on the left side of the faceplate. It is designed to work with Goal Zero solar panels and is capable of taking in 200 W of solar." · "8mm Solar 200 W max 200 W max 200 W max"
