That's not a resource, that's a guy talking, and it's also out of context speaking only to generalities.
Here's what my charge controller looked like this morning:
The panels were at 100V before current was even produced. This was during civil twilight while the sun was below the horizon. Even less light than is available during a "bright" cloudy day, my 3kW array produces 800-1000W. If it's a dark gray stormy day, I'm lucky to get 300W.
Once it found the MPPT voltage, the 3kW array was only producing 200W - less than it does on a very cloudy day.
Data be damned. Do what you want assuming you even both getting off grid. Good luck.
