The intention with these panels is to get some extra production that we need to run our work computers from anchor next summer.
That is bloody brilliant!! I would not have thought about running panels up the mast like that. Should really increase the solar cell Square footage on a monohull while at anchor.

You used batten cars? Is that strong enough to support the panel by itself?

The lines coming off the aft end, look like they go to the backstay? Are you using the lines to support the panels?

I just realized you could do the same off the front of the mast using the Spinnaker track. Especially if you had a longer track to store the Spinnaker/whisker pole on the mast. Not sure if the furler would produce shadows.

Re: Illustrated Guide to Solar Installations on Boats

I am looking to replace my old Kyocera 140w panels (2) with new 180/200w high efficiency marine grade Perc monocrystalline panels,and don’t want to break the bank. Recommendations?

I forgot to mention that these are rigid panels. The dimensions are approximately 59 1/4”x 26 1/4”. My budget is $300-$400 per panel.

I will go for the domestic panels and post my installation (next spring).
Now it took a little longer and we made it to Portugal. But here is what we did on our FP Mahe 36:

In 2021 we installed two domestic LG NeON Bifacial 2 400 Wp solar panels, one on our new dinghy davits and one on the fixed bimini. Dimensions are 2 m x 1 m each. Total of 800 Wp.

We use a Victron Smart Solar MPPT 100/50 for each panel. Nice visualization and configuration via bluetooth. We also use a Victron 3000 VA inverter.

We decided to not go for pivoting function on the davits because we are lazy and did not want to build something which we know we will not use after a couple of days.

The panels and chargers were approx. 1200 € plus all the bits and pieces (I was surprised how much small stuff we needed for our electrical refit and at the end, this was a considerable amount of stuff and €).

Total Efficiency: it's amazing. We never run out of electricity. Our lifepo 400 ah batteries regularly were back to 100 % before lunchtime. Even if we run our watermaker on 220 V for 2 h the solar system filled up the batteries very fast. And we saw some almost 500 watts on the panels due to the bifacial. It really works, especially on the davits with reflection from the water.

Even on cloudy days the panels produce a considerable amount of energy. When you think today will not be a big production, you will see some 250 watts on each panel constantly.

Until now there is no issue on our system or installation. We build our davit form 50 mm seawater resistant aluminium tubing and coincidentally saw, that lights and speakers in theater and live events are mounted on the same sized tubes. Guess what: the connector fittings are made from seawater resistant aluminium as well and are inexpensive

What would you do differently next time: We bought a wind generator on ebay, it was a very good deal (brand new) and we didn't know better. But we did not install because we wanted to check solar first. Trying to sell it now.

In the Portugiese winter we had a lot of nice sunny days but the angle was to shallow and there was not a big production to serve all the needs (especially for heating with forced air diesel heater). Therefor my recommendation would be not to buy an inverter but an inverter/charger (with some serious AC charging capacity of approx. 70 A @ 12 V or roughly 1000 watts) to use a cheap petrol generator. This would cost like 250 € more on the inverter/charger and some 300 € for a cheap generator, but is way better and cheaper than the hazel of installing and running a wind generator or using the main engine on idle to charge with alternator.

How has adding the solar affected your sailing or cruising? Adding solar was the contribution to be absolutely free to stay on the anchorage as long as we want and produce nice quality drinking water, cold beers and boil water for the morning coffee on 220 V AC

Summary: having solar is key for cruising

Re: Illustrated Guide to Solar Installations on Boats

Type and model and size of boat. Monohull Kaufman 47 Cutter

Total Panel Output (How much power can be generated?) 350W

Panel Size: How big are the panels? Individual? Total area required? 2 each @ 26" x 52"

Age of Panels: When did you install the panels? April, 2022

Panel Location:
Where is the panel located and does it cause problems there?
Over Bimini
Does it cause problems with any other gear or while sailing? Can't see the Windex through the overhead eisenglass anymore.
Does it cause windage problems? No.
Has shading of the panels been a problem due to location of the panels and surrounding rigging or equipment? No, but I'll be adding a flexible panel above the dodger with its own MPPT controller in the near future.

Type and Brand of Panel:
Who made the panel?
Renogy
What type of panel is it? Monocrystalline
Marine or Domestic (land) panel? Both
Origin? Unknown

Total Cost:
How much did it cost to build the system?
$1200USD
How much was each panel? $200USD

Total Efficiency:
Do you consider the installation efficient?
19.8% according to the RNG-175D datasheet
Please any comments that may help another improve efficiency, based on your experience. Too early to tell.

Damage? Has the installation been damaged by wind or corrosion or breakage? No

What would you do differently next time? Tips? Different type of panel? TBD

Any problems? Disappointments? Surprises? Dissatisfaction? Issues? Weaknesses of gear or system? The Renogy mounting kits seem flimsy and fasteners are magnetic. They were returned for refund. I fabricated brackets from of aluminum angle.

How has adding the solar affected your sailing or cruising? Less reliant on engine to charge house bank. Reduced fuel requirements adding energy independence.

Re: Illustrated Guide to Solar Installations on Boats

2003 Outremer 55L sailing catamaran

Total Panel Output: 2570W (3x 330W and 4x 395W)

Panel Sizes:
330W: Length: 1686mm (66.38inch) Width: 1000mm (39.37 inch) Height: 35mm (1.38 inch) Weight: 19kg(41.89 lbs)
395W: Length: 1690mm Width: 1066mm Height: 40mm Weight: 19kg

Age of Panels:
330W panes installed July 2020
395W panels installed November 2021

Panel Locations:
3x 330W panels in series over davits (replaced the factory installed 2x 160W panels). Lower than cabin roof and bimini means no windage nor interference issues. Shading from wind generator mounted adjacent to port and from mainsail, boom and mast when sun ahead.

2x 395W panels in series on bimini port side and 2x 395W panels in series on bimini starboard side. These are incorporated into the bimini with a central walkway between the two pairs. Shading from boom above. Some additional windage compared to original bimini as the panels project further forward and outboard than the original bimini. No interference with sailing gear.

Typically if we need full power we swing the boom out of the way.

Type and Brand of Panel: Both sets of panels are domestic: Phono Solar PS330M1-20U/H Perc Monocrystalline and SunPower Maxeon 3 SPR-MAX3-395

Total Cost: AUD10,600 split between panels (NZD270 each for the 330W panels and AUD415 each for the 395W panels) and frame/installation (NZD2995 for the davits panels with new aluminium box frame and AUD3100 for the stainless steel tube bimini frame), plus three MPPT controllers (Victron Energy SmartSolar MPPT 150/100 NZD1000 and 2x 250/60 AUD1680)

Total Efficiency: Good efficiency, but could be better if could tilt the davits panels. Bifacial panels probably would increase generated power.

Panels are grouped into 3 arrays based on shading and the higher voltages radically decreased the size of the wires required for the 9m and 12m runs to their controllers. Our wiring conduits did not allow for all the cables that would have been required to wire the 7 panels individually, nor do we have room for all those controllers, but that would have marginally increased the overall efficiency.

Damage? None yet. Will need to add protection from boom in case of topping lift failure.

What would you do differently next time? Tips? Different type of panel?
If they had been available would definitely have used bifacial panels for the davits area and possibly for the bimini.
Tilt mounting for davits panels; at the time the extra cost and weight of a tilting frame was prohibitive.
Change davits frame to make it easier for future panels upgrade; the current frame is exactly matched to the panels.

Any problems? Disappointments? Surprises? Disatisfaction? Issues? Weaknesses of gear or system?
None yet.

How has adding the solar affected your sailing or cruising?
Provide enough power to offset moderately heavy power usage (electric galley) even in poor solar conditions. Using panels to create the bimini hardtop reduced the size, cost and weight of the remaining fibreglass foam panel structure needed to complete the cockpit cover.
