Hanwha Japan Co., Ltd. has announced the expansion of its "Hanwha 20-Year Warranty System" for solar power systems to include all solar power systems equipped with solar panels sold by the company.
This system is a unique warranty service that combines manufacturer warranties with extended warranties to provide long-term support for natural failures of components in solar power systems. Additionally, it includes coverage for on-site repair labor and compensation for first-year power generation simulations, ensuring customers can use their solar systems with peace of mind over a long period.
■ Background of the Expansion
Previously, the warranty was limited to systems equipped with the "Re.RISE-NBC" series solar panels. In response to customer demand, the eligibility has been expanded to all solar power systems equipped with Hanwha solar panels.
■ Main Features of the Warranty System
It supports long-term use through three types of guarantees over 20 years from the manufacturer warranty start date:
・Extended Warranty: Provides services up to 20 years after the warranty start date, even after the manufacturer warranty ends.
・On-site Repair Labor Guarantee: Covers on-site labor fees for repairs in the event of natural failures.
・Power Generation Simulation Compensation (first year only): Compensates for the equivalent of electricity sales if first-year generation falls below expectations.
■ Eligibility for Existing Systems
While applications are usually required within a certain period after the warranty starts, the company is accepting applications for existing systems for a limited time. This applies to residential solar power systems that started their warranty on or after December 1, 2025, with an application deadline of June 30, 2026.
