Tigo Energy

Rooftop solar systems rarely fail for just one reason. Design choices, installation details, communication layout, inverter behavior, and maintenance practices all interact in ways that only become obvious after systems are operating in the field.

This technical session looks at lessons learned from real rooftop installations using Tigo module-level power electronics, including optimizers and rapid shutdown devices. Using anonymized field observations, monitoring data, and service trends, we'll examine common root causes behind system-level issues.

The goal is not to assign blame. It is to help installers, designers, and O\&M teams understand what the industry keeps learning the hard way - better design, installation, commissioning, and maintenance practices can reduce risk in future projects.

**Audience**

For solar installers, designers, commissioning teams, service technicians, and O\&M professionals working with rooftop PV systems that include module-level power electronics.

**What Attendees Will Learn**

*   How design decisions can affect MLPE performance and serviceability after installation
*   Common installation and communication issues seen in rooftop systems
*   What field data can reveal about rapid shutdown, signal, and monitoring problems
*   How TAP placement, layout, and commissioning practices can influence troubleshooting
*   Practical maintenance and O\&M lessons from systems already operating in the field
*   How to think about failure analysis without jumping to single-cause conclusions

We look forward to seeing you there.
