Off-grid solar costs $25,000–$60,000+ for a typical home — batteries and oversized arrays add expense. Grid-tied solar is almost always cheaper unless remote location.
Off-grid pricing
- Batteries for 2–3 day autonomy: $15,000–$30,000
- Larger array for winter: +20–40% vs grid-tied size
- Generator backup often recommended
Grid-tied vs off-grid
Grid-tied uses the grid as virtual storage — far lower cost.
