The following chart is the daily readings off my Out Back solar charge controller. This would then be the incoming Kilowatt Hours from my 6 Sharp 240 watt solar panels. From Jan 1 2012 to Oct 14 2012 there was No Data, because I didn't
have my solar panels in operation yet. Any other No Data areas was
from neglect of keeping track. My Outback charge controller keeps a
record for 128 days then it erases it as new data is being recorded. The
following is my daily incoming Kilowatt Hours From Jan 1 2012 to
April 5 2014. It was tricky trying to get this on here from the Excel spreadsheet also, but it was a good learning experience. This last winter we had a lot of snow, and not once did I get up on the roof and clean it off. The previous winter we had a lot of snow also, but I did clean it off quite often when it quit snowing and the sun came out. February 14-28 2014 I was away, so once things charged up it seemed to just hold at .70 area each day as the batteries were full. Just thought I would point that one out. There was snow on the panels when I left, but I can see from the incoming wattage that it melted off shortly after. I turned the deep freeze off for this holiday.
I do have a record of my State of charge every morning for quite some time, but then I kind of got lazy in the later days. It's all in books. I didn't get that info on here yet. Maybe some day I will get a little more organized and find a simple way to push a button and have it all here, but just to give some perspective on the situation, I will say that usually in the winter time with the deep freeze running and in the house(which is going to change next winter), my SOC is usually in about the 90% area. Sometimes 92% and sometimes 87%. So it drops usually around 10% from the previous days full charge. My honda 2000 runs about 3.5 hours each day to charge it back up again. Sometimes I'll go a couple days before charging, but not very often. Very seldom do I let my battery bank drop below 80% SOC. My forced air furnace usually comes on in the mornings but does not run much during the day in the colder weather. I'm usually burning wood when it is colder than -10 celcius outside. The previous winter(2012-2013) I can remember waking up in the mornings to find the SOC at about 95%. I used to go 2 or 3 days before starting the generator then. That was before the deep freeze.
In other news, I did finally get my ceilings all up except the bathroom and one coat of varnish so far. I'll update on that with pictures soon.
