Solar & Energy in Hawaii
With the highest electricity rates in the nation, Hawaii has the highest per-capita solar adoption rate in the U.S.
Key Programs
Federal Solar Investment Tax Credit (ITC)
- 30% federal tax credit through 2032
- Especially valuable given high electricity costs
Customer Self-Supply (CSS)
- Current net metering replacement
- Requires battery storage or smart inverter
- No export credits to grid
Smart Export
- Limited export to grid allowed
- Lower rate than traditional net metering
- Helps grid stability
Unique Considerations
High Electricity Rates
- Residential rates often $0.30-0.40/kWh
- Makes solar highly cost-effective
- Short payback periods (4-7 years)
Battery Storage
- Often required for new installations
- Improves self-consumption
- Provides backup power
Excellent Solar Resource
- Year-round production
- Consistent output
- High capacity factor
