Benefits of AC PV Modules ¬ Simpler Field Installation – Micro. Inverter is attached to the PV module in the factory ¬ System design is simplified: Scalability More Value-Add in the Factory Less Assembly Work in the Field ¬ Increased AC Power Harvest 5% to 20% more AC Power Harvest ¬ Increased Robustness – Longer Unattended Operation – Remote monitoring of individual components – Single failure does not affect others in the array 3/9/2021 Larankelo Inc.
