I think it all comes down to how you use your boat. It you are at a dock every night or even every other night I think it would be foolish to install a $2k solar setup. If you anchor out alot that is another matter. If you live on your boat at anchor or a mooring, it is a necessity. Considering the cost of a new genset being $5K+ I would be far more inclined to do a solar and wind mix and still have $2k left over to go cruising with. That being said though we can live without A/C. If you can't then it's a whole different ball game.

PM'ing you Matty but just FYI for general knowledge, that looks like a good system mate although I know nothing of the manufacturers of the panels and components...the fact they give such a good warranty is encouraging although its only good as long as they stay in business....

The only thing I would change is instead of using those corner mounts I would but a piece of solid timber down both sides to 'spread the load'...and perhaps save the panel should some goose step on it...

"Home Power" magazine is on line , and many advertisers have charge controllers of very large capacity.

I'll be on a swing mooring in the middle if the river with no shore power. I need as much solar as I can get. Anyone Living in Australia would be stupid not to take advantage of it. Any outlay would sure to be paid off via the sun.

Good on ya, I love Perth. We lived there from 1988 to 1990. Tried to imigrate but could only get 70 of the 75 points needed to meet the imigration requirements. After two applications at $1K each we gave up.

Whilst I am doing my refit I am going to upgrade my solar system.
At present I have 2 x 85 watt Kyocera panels connected for a 24 V system.
I am going to add either 3 x 70 watt 24 v layflat stick on panels or 2 x 125 watt plus 2 x 50 watt lay flat stick on panels. This is brand dependant and cost.
This is not the cheapest way to go but is the most effective for my situation.
These are all flat, light and capable of being walked on.
They will be on the top of my wheelhouse , not in the general walk area but places where access is sometimes required.
I have a Plasma Tronics PL 40 regulator on the system at present so it will cope with the extra panels.
I don't want to split the systems as the smart systems will over ride one another so in reality only one system will, be doing the work and the other will be at idle.

This still won't cover all my power requirements but will cut down my gen run time and therefore increase my range.

Cheers
Benn

You're doing it wrong mate!

Do what everyone else is doing. Come by boat from indo and claim asylum.

The Australian government in all their wisdom will set you up with Australian Tax Dollars! They put you on a $60,000 pa payment, give you a house, allow you to bring your extended family over, give you credit cards, mobile phones and pay for an education! And it only costs you a trip over from Indonesia. No 75 points needed mate! Too fkn easy!!!!

Grrrrr rant over.

Then when that runs out, he could come into the US as an illegal immigrant (oops! I meant to say undocumented citizen), and collect similar benefits. Why haven't I thought of that?

You would be amazed at whats happening here Hendo, the US is traveling the exact same road Oz did about 15-20 years back....the media, schools, PC police, illegals, welfare....

We certainly are. The really sad thing is most people in the US are too stupid to learn from there own history much less someone elses.

Here is a man who added solar and has data to support his work. It comes from a Willard group I am part of.

Over a year ago there were some Email exchanges about Solar panels on boats,
and their usefulness - esp here in the Pacific Northwest. In light of that
I thought I would pass on this: A bit over 1 year ago we installed two
245watt Solar Panels on Viking Star. Before doing so I tried to get
information from others who had panels installed about their performance,
but all the 'information' was just gut feels. Well, I have been tracking
our panel's daily production via the Morningstar MPPT controller's data
logging capability, and today I sat down to work up a 1 year summery.

Some background:
O We installed two 245w panels, mounted largely flat and with no tilting /
aiming ability.
O We are using an MPPT type charge controller
O Have been in the Pacific Northwest the whole year
O Our 'Cruise' session is from March 1st to November 1st (Nov..Feb we
come into a dock somewhere)

Looking back over the year the actuals came within 2% of modeled (predicted)
output. During our cruising season (March through the end of October) we
produced an average of 124.7Ah/day, saved 245 hours of run-time on our
Kubota DC generator, which results in a raw ROI of 5.5 years. Figuring in
the Federal Tax Credit it drops to 3.9 years.

I have more details here if you want to see them:

After a bit more research I have had to change what panels I will add.
So as to keep the characteristics of the panels similar to the existing Kyosera 85 watt units and be able to use my existing controller I am initially going to add 2 x 90 watt lay flat panels.
I will give these a trial and if out put is as being predicted I will then possibly add another 2 x 90 watt.
This will then give me 265 watts at 24 V.
This is all part of my existing refit program.
Cheers
Benn

Hendo,
Hope you don`t mind me chiming in on this.
I have 90 watts of panels to each of my 200ah main batteries (the IG has an odd set up) via good digital controllers which tell you what is going on. A friend and I did the install, made my own mounting brackets,and I`m nowhere near as handy as you. I still have a genset, but also have happy well charged batteries, even a 25w panel serving the genset battery via a simple controller. I bought all the equipment on Ebay, don`t be afraid of that.
Panels need to be as unobstructed as possible,preferably no shadowing no matter how small, and need an airspace underneath to prevent overheating. I put fuses in the + line just before the batteries, found that tip in a helpful Don Casey article you should find by online search. You can locate your controller(s) in a good place, mine had to go in the ER.
Both PeterB, and Rebel, have solar. Rebel (John) lives in Perth, boat is/was? in Sydney,he recently fitted 400w of panel to replace a genset and is very approachable. In March he anchored in my bay and was running a fridge with ice cream in it. Try a PM.
In my experience the real panel output is about half the theoretical.

Hi Bruce!
Chime in anytime mate. You know that I appreciate all the help I can get!

I'll PM ya about your set up.

Cheers mate.

I am convinced I want to add solar panels to my roof. I am interested on how is the best way to mount the panels on the roof. My roof is a fiberglass roof that is honeycomb cored. Should I install rails? z-brackets? 2x2 starboard beams?

One supplier is suggesting an Outback MPPT controller, another is recommending the Morningstar - any reasons to go one way or the other?

Cheers
Henry
