In single-phase, 10 microinverters can be connected. In a three-phase installation, up to 30 microinverters can be connected on a single 20A three phase circuit breaker. Larger systems can be constructed with multiple AC branch circuits.

There are a variety of key technical differences between SunPower Performance solar panels and Conventional Panels, including the design and layout of the solar cells and the electric architecture—which combine to enhance the reliability, performance and aesthetics of Performance panels.

To go into a bit more technical detail, first, we laser cut each SunPower Performance cell into strips and layer them in a shingled configuration to create a ‘hypercell’. This shingled hypercell allows us to fit more active cell area into each panel, boosting power and efficiency. Second, Performance cells are connected with a flexible joint interconnection to offer multiple and redundant paths for energy flow. This allows us to remove the front contact conductive ribbons and solder bonds found in conventional cells that can block active cell area and deteriorate over time, leading to cell failures and power deficits. Finally, SunPower Performance panels feature a unique parallel circuit architecture that significantly limits power loss in shade and soiling. The result is a superior shingled panel constructed with commodity cells, outperforming conventional panels in efficiency, performance and reliability.

We built the Performance solar panels for high reliability, high efficiency and low degradation—driving an estimated 8% more energy yield in a fixed space over the first 30 years of operation when compared to Conventional mono PERC Panels1.

Your system will automatically shut down. Safety requirements prohibit the system from producing electricity during a power outage or blackout, because there is a chance that the system could feed electricity into the electric grid while utility workers are accessing the grid. The system will restart automatically when power is restored.

• Maxeon Gen 3: 1500pcs/box
• Maxeon Gen 5: 1200pcs/Box
• Interconnection tabs:1200pcs/box

There are a number of methods but often cell customers use a soldering iron. Also we have an instruction guide that explains how to connect the cell and tabs so feel free to contact us from the inquiry page.
