Cumulative Wind Energy

Last December, I put in an energy meter to keep track of production from the wind turbine.
It's installed just below the battery charge controller, on a custom bracket I made, to give it a fairly nice look. 
The meter isn't measuring 2-way traffic on the battery, as it's designed to.  It's just measuring inputs from wind that charge the battery, only.  There's a a little "0%" digit in the upper corner that you just have to ignore because it's meaningless.

The meter looks like what it is: a little energy meter I bought off of Amazon.  It's from one of the very few sellers that doesn't seem fly-by-night, because they haven't changed their name 6 times in the past year.  The name DROK doesn't inspire much, but it's been selling on Amazon for a long time and I've got several of their meters installed here and there, and happy with them all.

Anyway, it's been counting the kilowatt-hours for two months and it's been a pretty constant 4 kWhr per day for the whole time, except one week with no wind (or sun = Dunkelflaute).
The trend won't hold up through the rest of the year - I've already had an energy meter tracking my wind production years ago, and it was obvious that summer has less wind than the winter.  A safe forecast is 1000 kWhr per year. Same as what I measured several years ago, which is also showing in this trend so far.
