We are finally in our new home and working out the details.  6000 sq/ft of reward icf walls with agribalance foam in the attic and the garage floor.  8.64kw pv solar system on the roof  with enphase microinverters.  I have a report from energywise which tells us what our utility bills will be and pays them if we are over.  It is a two year guarantee. After being in the home for a couple of months we are trying to determine the effect of the icf and solar.  The energywise report states we wont be over 141 dollars a month for usage (12 month average)  Our bill last month was 69 dollars for the month and the solar system produced 930kwh of power.
Looking at the report, it states our cooling costs will be 241 for the year and heat over a thousand.
Does this seem correct for Leesburg, Va?
I would have thought that heating and cooling costs would be similar with the icf walls.
The report is too large to upload.  11864kwh for heat and 2673 kwh for cooling.
the solar company told me my system would provide 55% of our costs as we are all electric with two heat pumps.
We are happy with the home, but I am trying to figure out if running a woodstove all winter will help that much.

Why would you go through the extra expense and effort to run a woodstove when you have utility cost coverage for the first two years?

Great point ICFHybrid, after all this time, expense, effort, why not go Zero Energy?

We cleared a wooded lot and I hate to see the trees just rot away when I know they could be used for fuel.
Unfortunately, the timber market here is dead and I could barely cover the trucking cost to have them used for lumber.
I bought the stove also because of the tax credit of 30 percent which is now 10.  We are going to live here for a long time and we have an endless supply of oak to burn.
The stove is in the basement and I doubt I will be able to get the heat to the rest of the home.  I am just puzzled as to how many more Kwh it is estimated to heat the house rather than cool it here in Virginia.

Cut and stack for the future.

You have nearly three times more heating demand than cooling demand there in Leesburg in the first place and your electric heat pumps generally deliver more efficiency while they are cooling than when heating so that accounts for the bigger discrepancy between the kWh for the two seasons.
