I am in the final stages of constructing a composite panel Bimini onto which I will be installing 3 x 140 watt flexible solar panels- has anyone advice on best ways to run the solar cables though the boat- at this stage I am considering placement of the Victron controller unit on the rear of the switch board panel

Regards to all

i ran the cables for my 4x100watt panels down the port backstay, into the port line compartment, through the wall just forward & inboard of the shore power connection & through an empty chase that was in place under the aft bunk. I put my controllers(2) inside the small compartment next to the switch board compartment.  I don't need to see them all the time and the compartment is so shallow I don't store much in it.  Back wall comes out with 4 screws & the hinge removed.
Thinking of upgrading to solid panels since the semiflexibles are not as efficient...but that means adding an arch for them.  Wanted to avoid that but after a winter in the Bahamas, know I need more power.

Good Morning Breeze On and greetings from Australia
Would it be possible to send me a pic of the controllers in situ please?
Also is there any heat issue?
Also was there a reason for 2 controllers? My system was designed for me and has one - Victron Blue 100/30 MPPT

I am buying more expensive panels based on recommendation of a friend who went down the path before me albeit with his Motorhome - he originally purchased on price and expected to only get 5 years out of his first purchase of 8 x 100 watt as he considers that the market place is evolving quickly and they would be more efficient and less costly in 4 or 5 years at that time. His disappointment was that the cells started to fail, after 12 months and very quickly. The online retailer is no where to be found and he turned to the firm I have purchased from-they have a physical
presence via a warehouse claim to be the biggest f/panel supplier in Australia and excellent to deal with and hopefully the panels meet expectations. additionally I hope that by having fixed place panels they won't become prone to flexing as if I had installed them directly onto the canvas albeit they would have been smaller panels.

Hi we had two solar panels fitted to our bimini, cables ran down the bimini supports to new glands in the deck with the cables running under the rope lockers to the controllers which we mounted in behind the main control panel on the stern most bulkhead. Works well with no visible wires anywhere :)

Peter - Having trouble uploading pix.  I'll try to email them directly to you.  Each controller handles 2 panels in parallel.  No issues with heat.  We had relatively cheap, semi flexible panels from Renogy (made by HQST now) & they have started to degrade after just 2+ years.

How did you fix the solar panels on the bimini? I am also intending to install 2 panels on the bimini of my 385.

Hi, we used Solbian flexible solar panels and you can get them with a big plastic zip around all four sides, so just get the other half of the zip sown into the bimini. Very easy to take out again and has worked well for over two years.
All the best

Evening Alex

if you have usual canvas bimini than your panels should  be ordered with zipper attached.

My process is different as it is a composite bimini that I am making- if you want more detail please email me direct and I will forward you detail and several pics.

regards
Peter
