Key takeaways
- Panels are usually the largest hardware cost.
- Batteries can double total cost for off-grid systems.
- Balance-of-system parts add meaningful cost.
Typical cost ranges
| Component | Typical range | Notes |
|---|---|---|
| Panels | $0.40 - $1.20 per watt | Cost drops at higher wattage |
| Inverter | $0.20 - $0.70 per watt | Depends on type and features |
| Batteries | $200 - $900 per kWh | Li-ion usually higher upfront |
| Balance of system | 10% - 25% of total | Wiring, mounts, breakers |
What changes the price?
System size, battery choice, inverter type, mounting complexity, and local labor rates all affect totals.
