Looks like you scored!

I suspect, at 38 volts, or whatever.... its intended for a 24 volt system.

One other thing adamant and everyone else...

please when you post on the board - put a small bit of information in the 'intro copy' regarding the subject matter of the story.  It helps folks find relevant stories in the future and helps everyone to know what its about.

please do not post urls in the intro copy.. they wont work, and often times they'll scew the appearance for the whole front page for everyone!   I try to get in there and fix it up as soon as possible when that happens.  Its one of those weird little bugs about this software.  No biggie though.

Nice panel and the price looks right!  Congrats.

It looks like a 36V panel with about 4" polycrystaline silicon cells from the picture, that should put out a top voltage of about 22V or so.  It is probably a 12V panel at about 50 watts or so.  It is a good deal as a new one would probably run more than double what you got it for.  Wait.... found it!

It is a Hoxan Model H4810

http://www3.telus.net/pearen/Reference/pv_specs.htm

Pmax: 48 watts

Vpmax:  15.80 Volts

Ipmax:  2.80 Amps

Isc:  3.20 Amps

Voc:  21.30 Volts

Type: C (I think this means monocrystaline)

Length 37.13 (inches?)

Width: 16.5  (inches?)

Weight: 13.40 Kg

Looks like a good deal.  Have fun with it, Rich Hagen

Whoops, meant to say 36 cell panel.

[adamant]

rich and dan;

thanks for your responcse....

ok I AM NEW TO THIS ALL !i been doing alot of reading.

rich:thanks for the link..i found it last week but had a hard time reading the chart..

1. can this be for a 12 volt system? if so how can i tell?
   
2. if it is a 24 volt panel can it be used to charge my 12 volts battery?
   
   

i found no reading about that.

thanks guys again,

anthony

with 36 cells it pretty much has to be a 12 volt panel...  Im sure thats what its for actually.  I dont think I ever saw a panel that couldnt be wired for 12 volts (Ive not seen that many).  But I dont think the cells can produce much more than about .6 volts - so 36 cells is good for 12 volts.

[ghurd]

Great deal either way.

Looks like a 12v panel to me too.

Tested by them, it sounds like a 24v. Most 12v panels put out about 20v in good sun. 24v panels put out 40v. Possibly the seller used an analog meter he didn't know how to read.

Most 24v panels I've used are 2 12v 'panels' in series. Rearanging the jumpers in the box so the 2 'panels' are in parallel give you a 12v panel. Some of the 12v panels can be wired for 6v.

BTW. The new thing is 18v nominal, making it easier for grid tie inverters (huh?). I think 18v have only been around 2 or 3 years.

[richhagen]

Your panel based upon the model number, (and even if it was not known based upon the design) used alone, is for a 12V system.  Unless you have battery bank of flooded batteries above approximately 400 Amp Hours or so you will need to use a charge controller to prevent over charging the batteries.  Rich Hagen

[adamant]

can you recommend a charge controler?

i am charging 2 trogan t 105

I like Morningstars.  This panel could probably get by with the Morningstar SunGaurd-4. The SG-4 is rated for 4 amps, if the panel goes past 4 amps, which I doubt, you'll need to step up to A SunSaver-6 (6 amp).

The SG-4 and the SS-6 work the same, mostly...

Both are temp compensated, series controlers, and true PWM.

The SG-4 has a peak V of 14.1v good for sealed, but work well for flooded also.

The SS-6 is adjustable to 14.1(sealed) or 14.4v(flooded), and had a green LED indicating daytime.

Be careful not to short the panel wires while the controller is connected, other than that they seem idiot proof (tolerate reverse connections, etc.).

SG-4's run around $30, SS-6's maybe $50. Readily available.

A SS-6,  SS-10 (amps), or SS-20 may be better to allow for adding more panel at a later date. The SS-x line are available with a LVD (low voltage disconnect) for suppling current to a load. Load amps can't go past 6, 10, 20 respectivly.

I don't think most people would see any differance in the day to day use between the 2. I've been puting in 50w panels with SG-4's for several years with very good results, 98% with flooded batteries. Very reliable.

I have a couple of old trace c-12's, they've never given me any problems and one's been up since about 98 or 99 and the other for about 3 years.  They also contain an integrated lighting controller which can be set as a lighting timer, or dusk to dawn. I also have a C-40, but that is way overkill for your current setup.  I have no interest in or affiliation with the company that makes them.  Rich Hagen

[ghurd]

Yes, I sell them. I didn't mean to hide it. I don't really do much mail order, so bragging that I sell something here isn't going to do me any good. Sorry if it sounded like a hidden sales pitch.

I like trace too, for large setups.

But this is a $122 panel, that will work nicely with a $30 or $50 controller.

List on the Trace, add the temp sensor, and that's more than this panel cost.

[richhagen]

I didn't know you sold parts, I'll have to send you an e-mail when I need parts.  Rich Hagen

I can do pretty good for some things. Others I buy retail for less than I can get it wholesale! I mostly only stock solar related stuff. Nothing too big, fancy or unusual. Lots (Boo-Koo) of LED stuff. A majority of my bussiness is on demand for the semi-local Amish market. My catalog is "What are you looking for?", as in we stock that custom made LED bulb. Locally, they all want the same things. Am I hacking the site? Anyway, ghurd at noi dot net, for a short time more. 'SOLAR' in the heading or it'll get spammed out.
