Re: Sliding Solar Panels on Cal 28 pushpit

Maybe something like an aluminum camera tripod leg or a monopod would work. I would worry about the wind using the leverage of the extended panel to rotate on your around the top rail bracket.

We're watching in Ky too. Obviously, your not making those clamps in your garage!

Continued from above message:

TAYLOR MADE Rail Mount Flag Pole Socket at West Marine

WEST MARINE 007_214_005_502 at West Marine

Get two of both to mount one leg to the rail and one to the bottom of the non-sliding solar panel. The bottom one would have to be able to rotate, but once the tripod leg is locked in position, it should be fine and stay where it belongs.

Re: Sliding Solar Panels on Cal 28 pushpit

I have installed one 85 watts solar panel on each side of pushpit using sturdy nylon clamps. All was well till a real big wave crashed on one panel (who was on ''storm position'' : upright and tied). If you sail offshore, try put your panels high, over davits or arch. If impossible, you need beefy attaching points. And even that won't prevent the panel to be fold like cardboard by the force of water.

Re: Sliding Solar Panels on Cal 28 pushpit

Just got a price from the UK importer for the solar mount in post 35above. £190 ($300) for the 40mm mount seems quite good compared to the other US manufactured mount mentioned earlier in this thread.

Pictures show work in progress of a support structure template and solution to extend or retract panels with lines.

Nope! I have fit checked the panels and they will not go back in place until everything else is finished.

Still on the list;
Finalize support structure template and fab with SS tubing.
Install second set of cam cleat and fair leads
Fab and install fairlead tubing on corners.
Create threaded epoxy bushings in place of any new penetrations.
Paint
Put panels on frame

Finish electrical- I have the rogue mppt controller and a combiner box with four circuit breakers mounted to a board, installed on the backside of the cockpit footwell, in quarter berth. I also have finished a battery box that holds four t-105 batteries. I need to wire between components, make interconnects etc. and then get working on the distribution panel. Fun fun fun

I'm making progress, albeit slowly!

Fresh paint on the frames.

Machined dies for pipe bending.

Procured the tools required to polish stainless tubing.

Could you please tell me where you found those rail mount brackets in pic 2 and 5? I need 2 or 4 of them. Thanks

Willardj,
Those parts are not an off the shelf item.

I bought a two inch by two inch section of acetal and machined those blocks. Pictures of the process are back a page or two, I think post #29.

Re: Sliding Solar Panels on Cal 28 pushpit

Cool I can do that. Where would be a good place to find some of that?

Acetal is also known by the trademarked name delrin and can be purchased from mcmaster, onlinemetals.com or just about anywhere selling plastics.

Do you have a mill to be able to cut the semi circle? These blocks are not hard to make, as long as you have the right tools.

I have the fair lead tubing polished and cut to length. Tomorrow I will mill slots in the tube and epoxy to frame.
