01
Your property
Every value can be changed later.
Do you have a generator now?
Empty homes still keep heat at about 55°F, the fridge and freeze protection running.
If you know it, this replaces the estimate from your checklist.
Essentials: fridge, lights, internet, well, heating controls.
How long the batteries carry the property through cloudy weather before the generator starts.
"Most of the year" lets the generator cover the darkest winter weeks. Designing for December usually doubles the array.

Solar and equipment
Skip anything you're unsure of.
Do you already have solar?
Usually on your contract or the inverter label.
What kind of solar interests you?
A building-integrated solar roof is the roof itself: the solar is built in, in place of shingles or metal panels. Choose as many as you like.
