In 2018, Tesla Project Titan Quietly Replaced Solar-Panel Parts That Could Cause Fires

In the summer of 2018, Tesla initiated a massive undertaking — a stealth replacement of solar-panel parts across the U.S.A., called Project Titan.  
The faulty parts in question were connectors and optimizers.

These parts are supposed to regulate the flow of energy and heat to a solar panel, ensuring that as much power goes through the part as possible without overheating. Overheating can lead to a fire.

"A portion of modules and optimizers from various manufacturers were made with connectors from Amphenol, a part that was commonly used across the industry at the time."

These parts were "quarantined" as part of Project Titan and were either reworked and put back on roofs or scrapped.

One document viewed by Business Insider put the number of parts that needed to be quarantined sitting in warehouses and distribution centers at over 120,000 as of last September. A Tesla representative said this number was not accurate.
