3KW. Wow. Just wow. I have a 6KW generator (8KW surge) for when the power goes out—a common occurance in NH during wintertime. Cost me about $700, with another $300 for the male-male cord and disconnect switch at the breaker panel.
Pray tell, how well would that solar system work here in January during a snowstorm?
Chances are that it wouldn't work very well for anything that does not receive a lot of sunshine. Solar probably would do great in Colorado which gets 300+ days of sunshine per year.
