For solar, the method I use for real world ‘calc purposes’ (obviously region dependent) is to de-rate the panels by 50%, and to assume a 60% refer duty cycle - add to this your normal usage, and battery’s starting SOC (state of charge*), then plan for a day or two of minimal harvest..
* will require a Lithium capable battery meter like a Victron (smart shunt or BMV 12) or equivalent…
