Wow! That's so awesome!  A huge "solar spill"!!

Good to see your graphs, Looks like a perfect solar month

I had similar results for May, best May ever for PV here in NE Ohio.  Not as good as yours Bill but I have some shading issues and (I believe) less capacity at 16.5kw.  Total net export for May was 891 kwh

Yes it is always nice to see those Sun Hours go thru the roof or more correctly stated come down as electricity from the roof, or whatever one has out under the sun on tap.   Also here the sun really helps with pumps to irrigate crops when there is less rain to do that passively.   Keep up the good works there Bill and thanks for the info.

Hi:

My May export for the May billing period (24th to the 24th) was 779KWH's, which is pretty high. Not sure if its the highest ever because in the days before EV's, I used to get $400 and $500 dollar checks from PPL. 

I am still testing my barn array (East/West) on the ground (Messy) and I just upped the string from 8 to 9. Tomorrow I will put the other 9 down in parallel (5800watts) and see if the charge controller can handle at its maximum DC rating 4800watts. The voltage under MPPT hits around 490-500VDC. Max MPPT voltage is 510VDC, so I am just under the wire. It will still run from 510-550VDC but not under MPPT.  OCV is about 560-570'ish. Max feed voltage is 600VDC. I may have to put some Zenier diodes across, rated at about 560VDC, just to beginning to "clip off" if it heads for 600VDC on cloud edges if on "standby" no load, or off grid with full batteries.

My arrays are 11.77 tracking and what was on the ground for May, 2.6KW flat.

I love problems that are related to too much SUN...LOL...

Hi, 

I am new to tracking solar production.  We have just moved into our Design Certified Phius ZERO 2021 house.  In May, we were positive and exported 1.4 MWh to DTE.  No checks, the Michigan Public Service Commission and DTE are locked in a discussion around Solar Renewable Energy Credits for distributed generation customers.  It has been very sunny and dry.  We have had .92 inches of rain in May.  Normal is 3-4 inches.  

Hello. Your house sounds interesting. Tracking is a love hate relationship. 30-40% more energy but a system that now moves over static. Most people today just throw more panels at the energy required rather than track. Goes to cost per watt. When panels were expensive, tracking was approached more eagerly. Cheap panels, why bother to get more TOTAL energy per sq. foot of active "collector". I enjoy though the flatter production of a tracking system. Has "value" when in off-grid mode, not being so peaky.

Weather with allot of sun, seems to come at a precip cost, here to.

Regarding your states electron tug of war; you must remember, it is demand destruction for the utility monopolies, knocking at their homes door, ever louder. And with it comes the increasing rumbles of 'socialize the grid'.
