You can think of it like a marathon runner.
- A module component guarantee promises the runner will run at certain speeds for the race if he is running on a treadmill in controlled laboratory conditions.
- The Autarco kWh guarantee promises the runner will finish the exact race you want him to run, in a certain period of time, regardless of the weather.
A module performance guarantee promises the solar modules will performance at a % of their laboratory tested output after certain periods of time if you test them under the same laboratory conditions.
The Autarco kWh guarantee promises a minimum value of solar energy produced (kWh) over a fixed time period. The value of kWh guaranteed is tailored to your exact system details and is measured using standard solar monitoring.
