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.
Cost guide
Solar system cost breakdown
Typical costs for panels, batteries, inverters, and the balance of system. Use this to plan your budget.
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.
