Corrosion Design Framework Enhances Coastal PV and BESS Longevity
A unified corrosion design framework is implemented for solar and storage projects in Maui, Hawaii, addressing environmental challenges to extend the service life of equipment. This approach emphasizes material selection and design consistency over minimum code compliance to mitigate corrosion risks in coastal environments.

The corrosion design framework applied across solar and energy storage sites in Maui, Hawaii focuses on enhancing durability against environmental factors. From 2023 to 2026, a portfolio designed for Johnson Controls incorporated Type 4X enclosures in 316 stainless steel, copper conductors, and sunlight-resistant Schedule 80 PVC raceways.
This comprehensive design strategy aims to counteract the corrosive effects of salt, humidity, and UV exposure, which are critical in coastal environments. The ISO 9223 classification assists designers in anticipating corrosion challenges, ensuring long-term reliability in projects expected to last 20 to 30 years. Adopting this framework could influence best practices for similar coastal projects across the U.S. and territories, minimizing avoidable failures.
