Hawaiian Electric: Smart Renewable Energy programs
- New Hawaiian Electric customers apply through the Customer Interconnection Tool. The current options are Smart Renewable Energy Export (export bill credits, no project size limits), Smart Renewable Energy Non-Export (no export), and Bring Your Own Device Plus (incentives for a new battery that's dispatched during specified periods). Participants need an advanced meter. Source: hawaiianelectric.com (accessed 2026-10-20)

Is solar worth it in Hawaii?
It depends on your bill, roof and utility rules. Here is an estimate for a home with a $150 monthly electric bill and a south-facing, unshaded roof, before any incentives:
- Residential electricity averaged an estimated 46.28¢/kWh in Hawaii (January–July 2026), above the U.S. average of 18.19¢ (1 of 51, highest first). Source: EIA Electric Power Monthly, Table 5.6.B (accessed 2026-10-20)
- Small rooftop systems in Hawaii produced an estimated 1,796 kWh per kW of panels in 2024 (2024 small-scale solar generation divided by average 2023–2024 small-scale capacity). Source: EIA Electric Power Annual 2024, Tables 3.21 and 4.7.B (accessed 2026-10-20)
- Estimated system size: 1.7–2.3 kW, producing about 3,592 kWh a year (estimated).
- Estimated installed cost: $6,000–$10,400 before incentives, using $3.00–$5.20 per watt. Source: Lawrence Berkeley National Laboratory (2024 installed prices, 20th–80th percentile; accessed 2026-10-20)
- Estimated simple payback: 3–7 years. Savings depend on how your utility credits exported energy (see above).

A note on the federal tax credit
The federal residential clean energy credit (25D) doesn't apply to expenditures made after December 31, 2025. The IRS treats an expenditure as made when installation is completed. Source: irs.gov (accessed 2026-10-20). This page isn't tax advice.
