Maui County is rapidly embracing solar energy, with nearly half of all single-family homes now equipped with rooftop solar systems. According to a recent update from Hawaiian Electric, the adoption rate in Maui County has reached approximately 47%. This showcases a notable commitment to sustainable energy practices within the community. The increasing adoption of solar energy across the Hawaiian islands reflects a larger trend toward renewable energy integration. In fact, Hawaiian Electric reported in September 2025 that customer-sited rooftop solar and battery storage surpassed 1 gigawatt of generating capacity across its grids.
This trend presents both opportunities and challenges for Maui's business landscape. For entrepreneurs, the growing demand for solar panel installation, maintenance, and related services creates business prospects. The Hawaii Solar Energy Association notes that this increase in rooftop solar adoption demonstrates how local action can deliver affordable clean energy and bolster the island's resilience.
Investors can find interest in sustainable energy projects and companies in the sector, while the real estate market could see increasing demand for homes equipped with solar panels, potentially impacting property values. Furthermore, the growth in solar energy capacity contributes significantly to Hawaii's commitment to decarbonization and clean energy goals.
