Bill > SB669

This bill requires new single-family residential developments with 20 or more dwellings to include rooftop photovoltaic (solar) energy systems beginning January 1, 2026, with provisions for obtaining variances. Developers can request a variance from the Hawaii State Energy Office by submitting an application through a licensed architect or electrical engineer, which must demonstrate either that solar installation is impractical due to poor solar resources or cost-prohibitive based on a 25-year life cycle cost-benefit analysis. The bill defines a qualifying rooftop photovoltaic system as having at least five kilowatts of generating capacity and including an energy storage device like a battery. Variance applications must be publicized within seven days of receipt, and will be automatically approved if not denied within 60 working days. The chief energy officer is authorized to adopt administrative rules and collect fees for processing variances, with any collected fees deposited into the energy security special fund. The legislation allows counties to establish their own implementation procedures and does not restrict participation in utility demand-side management or public benefits programs. Importantly, this bill aims to increase renewable energy adoption in residential developments by mandating solar installations in larger housing projects.
