We back every component we install — because solar is a decade-long relationship, not a one-time sale.
Every YST Energy installation is backed by a comprehensive warranty covering manufacturing defects and installation workmanship. Coverage duration depends on the specific component, as outlined below.
Exact warranty terms are confirmed in writing at the time of purchase and may vary slightly by product brand and package tier. Your sales representative will provide your specific warranty documentation before installation.
Damage from external electrical surges not caused by the system itself.
Damage from natural disasters, flooding, or fire outside normal operating conditions.
Issues arising from repairs or modifications by non-YST technicians.
Expected gradual capacity reduction within manufacturer-rated tolerances.
Contact our team via WhatsApp or phone with your installation reference number and a description of the issue. Our technical team will schedule an assessment visit, and confirmed warranty-covered repairs are carried out at no cost to you.
