Portlock Oceanfront Residence
21.6 kW Residential Solar + 3 Tesla Powerwall 2 Storage

Oceanfront Solar + Storage Case Study | Hawai‘i Kai, O‘ahu

Sunspear Energy recently completed a premium 21.6 kW high-efficiency solar and storage installation on a stunning two-story oceanfront residence located in one of Hawai‘i Kai’s most prestigious neighborhoods at the base of Koko Head. Designed to maximize energy production while preserving the architectural integrity of the home, this system delivers exceptional performance, resilience, and long-term savings for the homeowner.

The system features a 21.6kW solar array paired with three Tesla Powerwall 2 batteries, providing ample clean energy for daily use while ensuring reliable backup power during grid outages. With its oceanfront exposure and high solar potential, the property is now capable of producing a significant portion of its energy needs onsite and dramatically reducing utility dependence and protecting the homeowner from rising electricity costs.

This project reflects Sunspear’s expertise in designing custom solar and storage solutions for Hawai‘i’s unique coastal environments. From structural considerations and salt-air exposure to energy modeling and permitting, every detail was engineered for durability, efficiency, and long-term performance. The result is a powerful, future-ready home energy system that delivers clean power, uninterrupted backup, and peace of mind—day and night.
