Time for an upgrade: The first 36 watt system was an experiment for the mounting hardware and charging components. Now it was time to get serious. 36 watts barely kept up with our usage and the charger never caught up. I moved up to two 50 watt panels.  The mount for the vertical post remains unchanged. The clamps are machined filter brackets found on EBAY for race cars. They are exceptionally strong. The two thumb screws are tightened if the wind is blowing. This setup has been exposed to gail force winds.  |
 The next few slides show how the parts are assembled. The pieces are stored in my front storage compartment. Frame and vertical post on the left. |

The frames on the panels serve for most of the support. I was able to get rid of two pieces of angle stock from the last build. Commercial panels like these have holes pre-punched that accept a standard 10-32 blind nut. I use 10-32 stainless thumb screws to hold everything together. Assembly time is about 5 minutes
As with the other setup, I can rotate and change the angle of the panels.
I had a light weight PA stand that allows me to move my setup into the sun when the camper is parked in the trees. I have a separate 50 foot cord that gives me plenty of movement. The 50 feet has .5 ohms of total resistance. I have plenty of overhead to deal with the loss.
I once again used 30 amp connectors used in Radio Controlled power systems. The wire is Low voltage two conductor 12 gage direct burial used for outdoor low voltage lighting.
I added a new Morningstar 10 amp charge controller and a Watt's Up power monitor. The monitor displays energy (Wh), charge (Ah), power (W), current (A) and voltage (V)
The last item is a small 350 watt inverter for those times when I absolutely need AC power.
I have small parts and accessories in a tool bag.
I kept the old charge controller from my last install for a spare. On occasion, I have a neighbor with a dead camper battery. With the 50 foot extension the controller and the alligator adaptor I can use my panels to charge their battery without moving my panels.
50 foot extension.
Small parts bag with extra blind nuts, thumb screws and couplers.
