Tesla’s Solar Roof uses string inverters rather than micro-inverters or power optimizers, which means that partial shading on any section of the roof can shut down production for that entire string. This is a significant design limitation that competing solar installers address with panel-level optimization technology from companies like Enphase and SolarEdge.

This seems to be overblown. I've seen plenty of string inverters around without issues, I'm not sure why this being used against Tesla in particular.

Maybe should be rephrased, but still makes sense to me. They use inferior tech for a premium price.

But yeah, not really their unique problem. Just cheaper solution that is out there.
