Do today's solar panels put out full power as soon as they're hooked up, or do they ramp up for some hours?
A contractor removed and replaced my 14 year old solar panels. When he turned them on, I saw they were not putting out full power. He said they had to "charge up" for most of a day before reaching full power, and he left.
That sounded fishy to me, but I thought maybe today's panels have more electronics than my old ones. So I thought I'd check before deciding he was just shining me on.
(From my metering, it's clear that one of my three strings is not working.)
