Installers, contractors and solar service companies whose service area covers Hawaii.
No state does rooftop solar like Hawaii. About 45% of single-family homes on Hawaiian Electric's grids have solar on the roof — 49% on Oahu — the highest adoption rate in the nation, across nearly 119,000 grid-connected systems. It adds up: homeowners put another 73 megawatts of rooftop solar in place in 2025 alone. With the highest electricity prices in the country and a state law targeting 100% renewable electricity by 2045, Hawaii homes keep leading the transition.
The state still backs buyers directly: Hawaii's Renewable Energy Technologies Income Tax Credit covers 35% of a photovoltaic system's cost, up to $5,000 for a single-family home. New systems interconnect under the Smart Renewable Energy tariffs: choose the Export option and energy you send to the grid earns time-of-use credits at island-specific rates locked in for your first seven years — or choose Non-Export, pair the panels with a battery, and use or store everything you make. That is why most new Hawaii systems include storage.
The installers below work across the islands. Ask each one to model Export versus Non-Export on your actual usage and to size the battery for evening loads and outage backup, and browse our solar energy resources for guides to storage, net billing, and what to check in a quote.
