Off-Grid Solar Project Update 5-08-17

Our little solar project just got a little bit bigger, ok, a lot bigger. We’ve been a little slow getting this latest update in place as the Solar Controller we ordered from Amazon literally took 6 weeks to arrive (slow boat from China?).

 New Charge Controller

So here it is: 4 new solar panels for a total of 8, another 12v 100ah GEL battery for a total of 3 (yes we need more) and a new 80 amp solar charge controller.

 8 panels

3 batteries

Yesterday was bright and sunny and gave us a pretty good picture of how well the system was performing. The (8) 100 watt panels (4 monocrystalline, 4 polycrystalline) produced about 677 watts during peak sunlight for an efficiency of about 85%. We ran our modem, router, PC, fan, and several lights for a full 24 hours as well as the dehumidifier for about 3 hours without draining the batteries below 70%. Today we will see if the system can run our 15 cubic foot freezer for the day under partly cloudy conditions.

If you are prepping for a bug-in situation, off-grid solar might just be for you. I’ll be posting a review of the individual panels as I have purchased from 3 different companies so stay tuned!

Hope for the best, prepare for the worst.

Happy prepping!
