How this is calculated

Days to a full Jackery Explorer 1000 v2 by panel size and sun
Panels	Full-sun hours	3 sun hours/day	4.5 sun hours/day	6 sun hours/day
100 W	14.3 h	4.8 days	3.2 days	2.4 days
200 W	7.2 h	2.4 days	1.6 days	1.2 days
400 W (max input)	3.6 h	1.2 days	0.8 days	0.6 days

How refill time is worked out

A station can only take so much solar. Panel watts above its published solar input limit are clipped, and what is left is reduced to what panels deliver in real conditions. The battery's empty share is then divided by that output to get hours of full sun, and spread over the sun hours you get a day.

Peak sun hours change with season and place, so the table shows low, typical and high sun side by side. The formulas and the sources for each default are on the methodology page.
