Sanyo HIT panels used .20/watt...
« on: August 20, 2018, 06:25:19 PM »
I just bought 60 Sanyo HIT multilayer panels at 20 cents a watt!

Just letting you guys around San Francisco Bay in on this deal
,

ML Solar in Cambell has bought a huge amount of these, appear to be in good condition.

Unusual form factor and mounting and 4 inch cells......Sanyo's pan tented technology of a monocrystalline wafers with an anmorphous polycrystalline overlayer. 19.2% efficiency

There are going out the door quickly!

They are a commercial outfit and if this is not approiate repentant me........

20 cents a watt was just too cheap to pass up

Dave !! -

Thanks for posting this.  Have been looking for some PVs in this physical size.   Hope that these HITs will have a lot of life left in them.

boB,   am certain that this is the seller,  on craigslist:

https://sfbay.craigslist.org/sby/for/d/195w-sanyo-hit-mono-solar/6661420509.html

Hope that this is OK,   I have no financial interest in these PVs,  and do not know the seller.

73,   Thanks again Dave.    Vic

boB,

I bought the 200 watt panels for $40.00 ea. 

They are a bit different than the norm.......4" monocrystalline cells in a 8X12 matrix.....about 38" wide and 50"" long.. Do not mount like normal (??) panels with the aluminum box frame.. Best I can describe is a formed aluminum pan with 2" frame depth on the sides and u channel to the outside of the frame

Vic,

That is the ad.   They email me directly as I have done business there quite a few times.  They are a reseller of manufacturer overruns, close outs, surplus items, and buy out solar businesses gone out of business.   Word of caution...they do sell some non UL  non listed product.....Jeff is honest in what he has. He does stock Canadian Sun and a few others new but the overruns are the deal


They are about 50 volts at MPP and I'm not sure if I want to put them in series for a 24 volt system?
2 in series is just over 100 volts and would be a transform ratio of 4-1.... A bit high and will make the Classics run too hot...?any advice on that?

Excellent !

100V in and 24V out.  No problem !  Unless you are maybe connecting up 10 kW worth of panels.  THEN the Classic
might run somewhat hot.  I'm into over-powering for low sun days up to a point...  Not sure exactly what point though :)

Actually, it would current limit and possibly turn itself down when it did get hot.

Vic, no problem on the listing.  Good to know !

Hi David,

Thanks for the added info on the seller,   will try to copy  the contact info,   for further use.

If we did buy some of the 195 HITs,  it would be for an existing system that we installed in 2005  --  strings of three Shell SQ 175s,  string Vmp of 106 V,  Voc of about 133.5 V  --  on a 48V FLA system.   This is at the upper edge of voltages,   and,  this was using OB MX-60 CCs.   The HITs would have a string Vmp of about 110.6V.

We have switched this 2005 system from the MX,  to Classic 150s.   The highest Voc recorded by the MX was 141V,   do not know how to access the highest Voc  from Classics,   probably needs a Modbus reader.   With 72-cell PVs, FLAs and MPPT CCs,    just did not want to try to run strings of two.    Two per string yields 70.8 Vmps,   seemed just too low,  at the time we were designing this system.

The power rooms here are both A/Ced,   so the Classics tolerate the high Vin,  fairly well.   The second system is identical to the first,  except that it runs 60-cell SW245s in strings of three  --  about 92V  string Vmp,   which is better.

Thanks again David for the info ...   probably will not snag any of these HITs,  although they are about the correct physical size ...

FWIW,   Vic

I just got 40 of these, waiting on the MC3 connectors so I can get some up and running. I only have one Classic 150 right now though so will need another one.
56KW/h forklift battery on the storage side.  Currently have around 3000 watts of panels that get me around 1000W on the classic.
