WSW provides a two-year warranty on installation of grid-tie PV systems without batteries. There is a one-year warranty on installation of battery-based power systems and solar thermal (water heating) systems.

Charges for service call, travel, and mileage will apply if the problem does not originate with WSW installation or components. For jobs more distant than one hour's travel from our office in Coupeville, labor is covered, but charges for travel time, mileage, and/or shipping may apply.

Equipment is warranted by the manufacturer. Labor time will be charged for WSW troubleshooting and replacement of components beyond our one-year warranty period.

Damage to systems by earthquake, fire, flood or other catastrophic occurence is specifically excluded from our warranty.

Rates and policies are subject to change without notice. If you have questions, please contact us.
