Personally I rate gennerator runners up there with people that start vehicles up at sparrow fart and rev the bejesus out of them to warm them up, then hammer past campsites covering them in dust.
With the cost of solar setups these days being so much less than one genny, I see very little need for them.
Do I have one? Yes.
Have I ever used it? No.
To answer the original question, yes it is too early and too late to be running a generator.
I run the 3 strike rule,
Strike 1. I politely open the owners eyes to the fact that they are not the only people in the area and ask them to be more considerate.
Strike 2. I lose my politeness.
Strike 3. The generator starts to malfunction. Normally stopping at inconvenient times and becoming more and more difficult to restart each time it needs to be stopped, until they get the message.
