RV Projects Solar



This is how I usually become aware of a pending project.  It may have been mentioned in passing during a conversation.  Other times, I see the Director of Maintenance of Odin staring at something.  I can almost see the wheels turning.  Occasionally, I ask.  "What are you thinking about?"  "Nothing."  He's still working it out.


And then one day, after being distracted by FaceBook all morning, I realize he's gone.  I trip over a few tools.  Hmmmm, I better investigate, ie. go take some "before" pictures.


I hear foot steps on the roof, so I head out & up the ladder.  I've never successfully made it all the way onto our roof, but something is happening over there...


We had discussed taking the old King Dome off.  The dealer told us it was disconnected & we had no intention of fixing it.  However, removing it would leave some holes The Colonel wasn't ready to deal with yet.


HOWEVER, it's time. He's decided to put a solar panel in it's place (the exact one that we have four of on our sailboat), in the hopes of keeping our batteries healthy over the winter.  Heck, yeah!  I'm a big fan of alternative energy.


Back inside, on the ceiling of the living room, is the crank for the King Dome.  The most interesting part was discovering when the crank was removed, the foam insulation in our roof is over 3 inches thick!  Nice!  (The Colonel made a nice blanking plate to cover the hole.  You don't even notice.)




The solar panel is here!  The solar panel is here!  We allow airflow underneath our solar panels on the boat, but that's not desirable on an RV doing 60 mph down the road!  He fabricates a custom forward bracket to reduce lift.



Before:  Yes, our RV actually had a little solar panel & it worked!  But not enough oommph for a Missouri Winter.  (Look, I'm wearing jeans.  Brrrrr.)


After:  Yeah!  We have solar!  He was able to run the wires down through existing holes to a forward electrical relay panel.  Easy peasy.  It won't run the a/c but it will charge the batteries, we hope.  Stay tuned.  I'll update next June!

Solar Panel Mounting


Update 2013

You will read below where I have in the past preferred the lever action over the allen key action. After two years of using these, I can now say I prefer the allen key model of antenna mount with a small modification.
I took the allen head screw and had a small "T" welded to the head of the screw. This made adjusting easier (no longer needing an allen key) and more precise than the lever type.








To continue with the blog from 2011....

There are many ways of mounting solar panels. Here is one way to mount with a tidy way to raise and lower the panels.
In a storm north of New Zealand I lost a solar panel along with the temporary railing that I had it mounted on. I have since had the aft of the boat reworked with railing built so it looks like it was always there. Much stronger. Deciding that my previous attempts at methods to angle the solar panels were not that good, I have come up with the following idea for the rail mounted solar panels.
You will note the small vertical rail inserted half way along between stanchions. This was used to mount my actuator arm.

 For the actuator arm, I used a stainless antenna mount and  had made a stainless tube made with a thread at one end and closed off the other. This was screwed to the antenna mount.Apply some locktite to the threads as they may have a tendency to unscrew over time.

This is attached to the small vertical rail in the middle.  The solar panel  was mounted with white rail mount clamps which I had previously used to good effect. This time around though, I had to add spacers because the railing was curved to follow the lines of the boat.
At the bottom of the "solar panel actuator" the one inch stainless leg was placed in some pressure PVC pipe bought from a hardware store and this in-turn was secured to the bottom of the solar panel with leather on both sides of the pipe and the leather secured to the solar panel. I have found it necessary to apply some 4200 between the pvc pipe and leather; other wise the leather looses it's firm grip on the pvc pipe and the pipe will drop out. This allows free movement of the stainless piece of the solar panel actuator as the panel is raised and lowered. I used two different types of antenna mounts. One with allen key and the other with a turning lever. The one with the lever, I cut off short because you only need thumb tight and the lever would interfere with my lee cloths.


After trying both, I prefer the lever arm rather than the allen key type.
Read the mod above. The panel raises from full down to 30 degrees off the vertical. One could, if you don't have lee cloths, build the actuator arm with a curve in it near the mounted piece so that when raised it would allow the railing to not impinge on the actuator arm. I'm happy with 30 degrees off the vertical and lee cloths.
The lee cloths had small "U" shapes cut out and bound, so that the hinges and actuator arm could function. The lee cloths were secured to the railing and toe rail with cable ties. Lee cloths not shown here
