Notes for a tiny home
These figures assume 4.5 peak sun hours and 2 day(s) of autonomy. If your location is cloudier, your usage is higher, or you want more buffer, increase autonomy or array size. The button above opens the full calculator pre-loaded with this tiny home setup, so you can change any device, voltage or chemistry and see the system resize instantly — the example is a starting point, not a prescription.
