We went a year listening to a generator a few hours a day and being conservative in between. Last year we started using solar and never needed the generator. I can tell you that it's much more preferable.
It was pretty easy with 230w of solar, 345 ah of bank and we didn't run the microwave. I'd like to think that the 8-D along with the 16a the solar puts out could handle it but I'm looking to increase the size of the bank now as well as add a second 220w panel. The only time I want to hear our generator is while I'm inside watching TV with the air running and then I can't really hear it at all.
