I assume this is one of those questions that is answered all the time or is equivalent to "how long is a piece of string?" but I am here looking for some perspective.

I have an initial quote from an installer for 9 panels that will get me 77% of my energy use up to 12 panels that gets me 102%.

Do you guys have any advice on how big to go? I am in it for the savings, the wife wants to get rid of the power company. Any other things to consider?

Thanks in advance!

Added info I thought may be relevant before I hit post: standard pricing is 15¢ a kwh, they buy it back at 7¢. But once we have solar, we'll be on TOU. A battery will be in the future.
