I wish that it would be enough, and it will during the hip months. However, worst case I'm looking at the solar replacing ~25% of my heat November through January. The rest of the months it is a fair amount higher.

The chart below is a quick spreadsheet I threw together to estimate what the solar panels will do for me. The third row from the bottom is the percentage of solar that will replace natural gas usage. I'm estimating a ~340 therms of gas or $400 per year savings based off of my historical usage.
