4 – Renogy 100 watt SolarPanels
I finally got my last 2 solar panels for my array and got them mounted up and now I can produce a whopping 12volts at around 22 amps. That equals a production of about 264 watts. In English that means my batteries will charge up and top off pretty darn fast.
Yesterday was a nice sunny day and I have never produced energy before 7:30 or 7:45. Yesterday it started around 7:00.
