Re: Stus-List Solar panels

[Stevan Plavsa via CnC-List]

Lots of options and lots of info on google, you can even google "stus list:
solar panel" and find old list threads.
I did want to chime in and say that solar is the best. I am never plugged
into shore power unless we're cruising and spending a night at a marina and
that's more for the laptops, cameras, etc than it is for the boat. We don't
have a lot of demand (no fridge, AC, etc) so our little 65 watt panel does
us well. Consistently over 3 amps, 3.5 max, it's located on top of the
bimini. Two Trojan T-105s make up the storage. Setup serves well.

Re: Stus-List Solar panels

[Marek Dziedzic via CnC-List]

I have very similar (consistent) results, even though I am much further north 
(45 °).

 

I have a 24 W panel and I get a maximum charging current around 1.1 -1.3 A. My 
maximum charge per day is much less, but my batteries are never that empty. I 
think that the maximum I ever saw was just under 10 Wh in a day. This is 
certainly enough to keep the batteries healthy.

 

My solar panel is a flexible one that I put on the bimini. There is always some 
shading (a least, the backstay), so the efficinecy is not the best.

 

This is with an older model of Morningstar, but it has a digital charge 
monitor, so it tells you what is (and was) going on with the solar charging.

 

If you use refrigeration or generally, have big power budget and big batteries, 
you need much more solar power (150 W or more).

Genasun is pretty much the agreed best engineered MPPT controller though they 
don't do higher current.  They have varying options for battery chemistry and 
wattage.  If genasun is what you use then you'll basically have to plan on one 
controller per panel which is great for reliability and redundancy but may not 
be so good on your pocket book.  They also don't have digital volt/amp/watt 
outputs so you'll probably want to look at getting one.  Genasun also offers a 
boost feature which allows a solar panel that outputs less than the battery 
voltage to charge the battery.  Otherwise you'll have to ensure the panel 
voltage is greater than battery voltage and they won't start/stay charging in 
the morning or in the evening.

Just to talk numbers for a minute.  My experience is that a 100 watt 
monocrystaline flexible panel mounted horizontally at a geographic latitude of 
38° yields a max of 66 watts in the peek summer sun.  I get about 4 or 5 amps 
peek charge current but only at peek sun.IIRC I get a cumulative ~900 
watt-hours per day.

Re: Stus-List Solar panels

[Doug Welch via CnC-List]

i have 2 100 watt semi flexible panels wired in series mounted on the bimini 
and an epsolar (30 watt) MPPT controller. I bought them as a package with wires 
and connectors from a local outfit called makeasolarboat.ca (that has since 
gotten out of the business). my wife sewed zippers on the panels and bimini to 
attach them. The package was $1,100 CAD including tax. I subsequently purchased 
the charge controller remote display and MC4 connector disconnect tool from 
amazon for another $60 CAD. I mounted the charge controller in a cockpit locker 
and it became  too annoying to open the locker and crane my head in to check 
the status. 
I am very pleased with the performance of the system, even on cloudy days. Over 
the winter my wife will be completing the the bimini attachments by sewing in 
velcro for the flaps to protect the zippers from UV and I will be adding a 
stainless tubing cross piece to support the bimini. The panels don't weigh much 
but they weigh enough create pockets for rain water to pool in. I will be 
buying a smaller panel to mount on the winter cover to keep the batteries 
topped up over the winter. 
I am very happy that I made the investment. Its great to sail  6 or 7 hour 
passages with the refrigeration, electronics and autopilt running and still 
have the batteries fully topped up. 
Hope this helps
Cheers,DougCeltic Knot33-2

X 2 what Tom said! If it's been in fresh water since 88 it's probably been 
lightly used because of our colder climate and no salt water on the hardware. 
With a solar panel it looks like it's been cruised. 50k USD is a great price. 
Our boat is splashed in May and comes out next week. Only way to know for sure 
is a close up look! 

But I am jaded too.

Re: Stus-List Solar panels

[Marek Dziedzic via CnC-List]

I personally have a Morningstar controller, but I wanted two battery option (I 
don’t have an ACR).

If I were to do it again, I would go for a Genasun controller (they are very 
highly rated and recommended) and a separate ACR or something similar.

Re: Stus-List Solar panels

[svpegasus38]

I just bought 2 140 watt glass Solara panels with 2 Gensun MPPT GV-10 
controllers, and a Solar Monitor Watt Wizard. Mounted the panels above the 
bimini lengthwise. Bought the system from BRJ Solutions in Seattle. I could not 
beat his prices in an internet search. On a sunny day my batteries are charged 
by 1pm, running my fridge and led lights.
