The month of October we produced over 1.73 MWh (Megawatt hours) of power on the farm.
In the last month I have added a second sol-ark inverter, this changes how the panels are balanced. Since I only have one channel of solar power coming in I really need to consider adding more panels on additional channels now I have two inverters. With only 5500 watts coming in on each, one channel is simply not enough for two inverters. So I will soon look into increasing my panel count. But for now I am making a steady 1.7 megawatt hours last month.
That white stuff is not snow, but powdered lime. We are using it to attempt to keep the weeds down. We will know next year if it works or not.

I'm really seeing production drop as we head into winter. We peaked around 900kWh in the summer months, but October was only 360kWh. The shorter days will be a factor and we get more cloudy days. We will still save money by charging up the battery on cheap rate. I don't plan to get any more panels for now. I plan to do a summary when we've done a full year.
How would it work in winters
Not sure yet, will be my first winter using it.
I see :)
Damn! Quite the setup you've got there.
Thanks, its been a work in progress for a few years now.
With the heat kiling me over here would be great to have one of those powering up the house
Dean that is cool.
I enjoyed the addition of the solar panels to the homestead enough but should have expected a report on stats knowing you!
Do you have any idea how many megawatt hours your home and operation will take? Managing this system, especially if it becomes your only source, will be an interesting process. I have friends who run a cottage completely on solar and we drain that thins each year at a music festival there charging our phones! ;)
I see that the statistics you make are getting better, of course I really hope that in this job you succeed in doing it, keep up the spirit of my friend 💪
Looks like you out-produced me for sure this month. Darn Hurricanes and storm fronts, lol.
My setup produced 1.3MWh for the month, we still fed 570.4 kWh back to the grid, and I saved about $163.70 off my electric bill from the credits.
Of course charging my vehicle from the house electric and Solar throws my stats off a bit for comparison. Especially with the extended driving we've been doing the last few months. Not pictured here, but the vehicle has used 427.311 kWh, for a cost of about $55.53 to drive 1,325 miles last month. If my math is right, a gas car getting about 20mpg would have cost $231.87 for the same miles (assuming gas price of $3.50 per gallon). I'll be doing a more detailed post on the vehicle and charging vs gas with a more TCO view later.
If we could be able to produce solar power like this in my country, it could have help us over the epileptic supply of power
