That has to be THE most frustrating question, and just about every new user asks it. And the honest answer is always going to be "I don't know." How can WE know how you live your life to answer that question? Maybe you work nights and have no need for evening lights. That takes a chunk of it away. Maybe you are a Luddite and have no television or sources of entertainment. Maybe you only eat at home once a day so you don't cook or store food. Maybe you don't have a laundry room and use laundromats. We just don't know, and there is no "average".
That's like asking about gas mileage. We don't drive the same day. My gas mileage is moot as far as yours is concerned. You maybe have a 50 mile highway commute to your job where I have a 20 mile city street commute.
I do understand that people come here for information, but sign on and read a little bit first before asking things that have been addressed dozens of times already. It is really obvious and logical that it is based on consumption. AND, until you start getting specific, we don't even know if you are talking about a van, an RV, shed, a cabin, or a house. The FAQ and beginners sections cover all of this. Like I said, don't just hop on and ask. Read the FAQ, which leads you to the Beginner section. You can go from beginner to someone with a pretty good amount of knowledge quickly. I am living proof of that. I was a solar dummy before I stumbled upon Will's youtube and now his forum. With his sharing of knowledge, you can now remove the "solar" from that description of myself......
