Private Rooftop Solar
Rooftop Solar Options for New Projects
These programs are the available options for new solar customers to install solar panels on their rooftops. Some programs work better with battery storage, and others may restrict exporting during certain times or when circuit capacity is reached to ensure grid stability.
- Customer Grid-Supply Plus (CGS Plus) systems must include grid support technology to manage grid reliability and allow the utility to remotely monitor system performance, technical compliance and, if necessary, control for grid stability.
- Smart Export customers with a renewable system and battery energy storage system have the option to export energy to the grid from 4 p.m. – 9 a.m. Systems must include grid support technology to manage grid reliability and system performance.
- Customer Self-Supply (CSS) is intended only for private rooftop solar installations that are designed to not export any electricity to the grid. Customers are not compensated for any export of energy.
- Customer Grid-Supply (CGS) participants receive a PUC-approved credit for electricity sent to the grid and are billed at the retail rate for electricity they use from the grid. The program remains open until the installed capacity has been reached.
Quick Connect Pre-Approval Program
Quick Connect is a Hawaiian Electric program in response to the COVID pandemic to streamline the application process for turning on new systems beginning in January 2021. Customers who wish to install a new rooftop solar system on circuits with 30 percent or more available hosting capacity, under 25 kilowatts in size, or for Customer Self-Supply (CSS) and Net Energy Metering Plus (NEM Plus) systems regardless of circuit, and meeting specific requirements, will not need the standard approvals before energizing their systems. Working with their solar contractors, these customers can install and energize their systems and begin saving money but submit paperwork to Hawaiian Electric later.

For Net Energy Metering (NEM) Customers
In 2015, the PUC declared the NEM program fully subscribed and closed to new customers. We still provide support for existing customers, and have a new option (NEM Plus) for current NEM customers who would like to add additional non-export capacity to their systems.

Expedited Validation Option (EVO)
Contractors who maintain a proven track record of accuracy may offer you an Expedited Validation Option (EVO). This speeds up the validation step of your project with a simple form that vouches for the accuracy of their work without the need of comprehensive review on our side. Learn more about which contractors are currently EVO certified and what they must do to qualify.
The safe, reliable operation of the electric grid is important to everyone. The combination of utility system upgrades and leading-edge, customer-facing technology is providing new opportunities to connect more private rooftop solar systems in less time with greater efficiency. All new rooftop solar systems in Hawaii are required to use advanced inverters that help maintain a stable and reliable grid.
