 With the sun getting lower now its 10:30
Around 125° before my array gets to see direct  sun. June was at 8:30 am.
Seems like winter might be sunless.
My 380 watt array is adjustable.
Yesterday morning at 11:15 with the panels due south my meter said I was bringing in 147 watts.
I went up the hill and set them to the sun.
New reading was 275 watts.
Seems to be worth the effort to set it.
Setting At 143° Then turning  it once at 161° to 180.  keeps the panels within 18~19°
 Afternoons with batteries absorbing readjusting didn't really make much difference.

    I'm afraid you've been misinformed. The horizon is rising.

    I can scientifically prove that the world is in big trouble... Yesterday, we had about 2 minutes more sun than today. Tomorrow will be 2 minutes less sun than today
    • 12 hours sun per day * 60 minutes per hour / 2 minutes = 360 / days
    Based on my daylight models, in less than one year, the world will be in total darkness... Less than 1 Year I say! I demand that somebody do something now about Anthropogenic Global Darkening. Perhaps raising taxes on solar arrays will help.

    As an eco-fascist, capitalist pig, and Knight of NI, I say you shall not pass.  Nor shall your trojan rabbit.  The holy hand grenade of Antioch shall surely provide, on or about the winter soltice.

    More seriously, east-west array/panel tracking works best in summer.  In winter, slope matters more to catch the best of what sun there is.
    Off-grid.

    Functional sun trackers do both yet the experienced do not generally promote them. One might hope that in 2019 we could make a device that tracked the friggin sun without malfunctioning? But we don't.......grrrr.
