This has been happening for a few weeks now - midday, full sun (should be cranking 2.8-3 kW) for no apparent reason the solar generation drops to 10% of normal (0.2-0.4kW) & stays that way for an hour, or sometimes never recovers, or will recover if I reset the PW. I've just tried all the reset/reboot/power cycle magic and it hasn't changed. Seems like something is failing hardware wise, but as usual it's impossible to get Tesla to come out and look, let alone get to anyone at "Tier 2" to look at it. I do have a ticket open, so I guess in a month or so someone might look into it. I dunno about any of you, but this level of support really makes me sure to never buy a Tesla product again.
