16. Warranty Sunbank offers a 10 year limited warranty on the collectors, a 5 year limited warranty on the tank, and a 1 year limited warranty on all other components of the system. Warranty claims made on products with a manufacturer’s defect will be honored. Damage that occurs during or due to a faulty installation is not covered under the warranty.
