Every solar module comes with some form of DC Power Output Guarantee that typically lasts for 25years. Autarco modules also come with this Guarantee, but don’t be fooled; These guarantees are designed with large solar farms in mind, where it would make economic sense to send a bunch of modules to a testing facility to test under laboratory conditions in order to make a multi-million dollar claim. Sadly, they provide very little benefit to system owners in a rooftop solar context.
That’s where Autarco’s kWh Guarantee steps in. Autarco guarantees the value of useable AC output of your system based on the specific details of your roof, including shade. The monitoring system provides the information needed to track performance and make any claim.
