    Funny how that happens when your system is well designed.

    2.1 Kw Suntech 175 mono, Classic 200, Trace SW 4024 ( 15 years old  but brand new out of sealed factory box Jan. 2015), Bogart Tri-metric, 700 ah @24 volt AGM battery bank. Plenty of Baja Sea of Cortez sunshine.

    Are you down there? There is a rocket launch coming up the 30th of a Delta Heavy out of Vandenberg that should be great to see down baja way. It is the last of the class and the largest thrust in the world right now. 21 million pounds. I was in Vandenberg Wednesday when they scrubbed it for the 4th time in a week. Bummer!

    Your friends tracker is a Zome. They are mostly used for water pumping on farms and ranches because they need no electricity to track.
    I use them very occasionally and their strong points in simplicity and reliability are great. Their downfall for offgrid is they do not go back to east until the next morning when the sun warms the gas, they miss early sun. In baja they are fine but in colder climes this is an issue with the design. They also are not really a dual axis as their track does not change in height. It is an approximation. Still for Offgrid they are fine. It is harder to get alot of solar on them also.

    I will be down there starting on the 27th. I was on top of Catalina Island for the Wednesday launch attempt. Great place to watch as well. Perfectly clear skies.  One thing for sure, Baja is a great place to watch satellites and shooting stars/meteor showers.

    Funny, I was chatting with my neighbor one morning and all at once the whole rack of panels flopped over from west to east and started it's business day.  I may be wrong but it seems he has 8 (I think) , 125 watt 12 volt panels on it. I'll take another look this coming week.

    I bet Cat would be fine. My Brother in Law does launch and space weather and so we were at the balloon shop a few miles from the pad.
    Double bummer on the scrub.

    We have a very nice view up here and if you can, log into Nasa and get the space station schedule e-mail to your lat /lon. Satellites are great but nothing is as good as the solar panels reflecting when the station goes over your place. It can be a 6 minute show.

    Save me some dorado ;)

    Except for Iridium Flares !  Visible in daytime even, as bright as aircraft landing lights !!
    Use the link below, plug in your location.   Very bright reflection from flat antenna array, but the new generation of sats have  different antenna, and don't show well
     The ground track is tiny, only a couple miles across, so they are not always visible from everywhere.   Change the location from LA, to wherever you are viewing from.
