       In my previous pinned post I described an ongoing data collection experiment between 2 proximate homesteads in Southern Ontario attempting to answer the question.  “Can solarPV power a GSHP home in S. Ontario.https://techhub.social/@icanbob/111534501325422430#solarPV #wind/1

       @icanbob/111534501325422430 Here is the latest solar data up to 2024Mar01 in graphical form.    We now need 4.3MWh of seasonal storage in tank on Nov 1 to get us through the winter.   GSHP load is dropping as weather warms.   SolarPV output is picking up as the days grow sunnier and longer.  Graph also shows what seasonal storage would be required if the solar array was doubled in size./2

       @icanbob/111534501325422430 Many have encouraged me to publish this experimental dataset.    The draft of that effort is now online on my webhosting page.    I’ve added an hourly wind dataset to the hourly home electricity and solarPV datasets and they are published also.http://energyasicit.ca/solarPVpaper2//3

       Week of Mar16-22 was not very sunny and weather turned decidedly colder in my part of Ontario.    Net result is my seasonal storage went up by 100kWh to 4.46MWh.   Shows as the dip at tail of graph below.   Days are getting warmer and longer,  so should be turning up soon./4

       The last week of Mar has been somewhat sunny,  but nights are still -5C.   The GSHP load is still high which overwhelms the surplus sunny days still.

       Weather is still cold enough for GSHP load to overwhelm solarPV output.  Long range weather forecast has a turn around coming up with the expectation of a seasonal storage build beginning to show in dataset.   Historically the GSHP is not required into May./8#solarPV

       Latest graph reflects the warmer weather and longer daylight days.    We are starting to see the seasonal surplus building out from the spring bottom./9

       Wind in Ontario cannot support a GSHP without an impractical amount of seasonal storage.     The description of this dataset and the 2 input variables (storage amount on Nov 1;  scaling factor to convert aggregate Ontario wind stats into single home dataset) is contained in the online report herehttps://energyasicit.ca/solarPVpaper2/1000k homes scaling factor is closest to annual wind GWh in Ontario / annual  MWh for my GSHP home/10

       It’s a wrap.    The GSHP heating season is done.   According to dataset the required seasonal storage on 2023Nov1 was 4550kWh.    The amount of accumulated seasonal storage build back on 2024May1 was 882kWh.     Is solarPV capable of supporting a GSHP is Ontario?   Short answer is NO.  Not without impractical/uneconomical amounts of seasonal storage./11
