wheels 543 Posted September 27, 2016 Share Posted September 27, 2016 Tuners Auctions are selling lots and lots of Panel cheap. All started as $1 auctions.The only issue is that it is Auckland and for some silly reason, Turners state buyers must pick up. I reckon Turners would get btter prices for stuff if the would freight. But anyway.So if you can't make it to Auckland to pick up, maybe someone could arrange to be a freight forwarder for a bit of remuneration.http://www.trademe.co.nz/stores/turnersauckland?cid=10 Quote Link to post Share on other sites
Clipper 343 Posted September 27, 2016 Share Posted September 27, 2016 Smoke damaged? How is a panel damaged by smoke? Quote Link to post Share on other sites
1paulg 17 Posted September 28, 2016 Share Posted September 28, 2016 Smoke damaged? How is a panel damaged by smoke? Good question - another thing - would the wiring be suitable for marine environments? Quote Link to post Share on other sites
erice 732 Posted September 28, 2016 Share Posted September 28, 2016 smoke is an extremely fine dust of mainly carbon once it settles on stuff it can be very hard to wipe it all off and make things look "brand new" again have not heard of solar panels specifically wired for marine enviroments presumably that would mean tinned wire? which i haven't seen on 4 solar panels on boats they are already pretty well weather sealed Quote Link to post Share on other sites
wheels 543 Posted September 28, 2016 Author Share Posted September 28, 2016 Solar Panels are well sealed and waterpoof. They should also have been in boxes, so smoke would be smell rather than actual smoke. Just not acceptable for full and normal retail I guess. Although you would think the owner could have had a " fire sale" and made more than I would expect an insurer to pay out.There are no such "Marine" panels. They are all made for the same outdoor environment and suitable for Marine environment. Quote Link to post Share on other sites
grant 40 Posted September 28, 2016 Share Posted September 28, 2016 at least the 250w panels have some decent sized cable and connectors on them, there they look new and as wheels said, if they were in boxes or wrapped some very good bargains could be had there Quote Link to post Share on other sites
1paulg 17 Posted September 28, 2016 Share Posted September 28, 2016 At the home show I enquired about a suppliers brand being suitable for marine use and was told that particular brand wasn't recommended so I assumed there may be a difference - possibly with the sealing of the connectors but maybe that person didn't really know ?!

wheels 543 Posted September 28, 2016 Author Share Posted September 28, 2016 There are also some Batteries going cheap on Trademe. A large number, pulled from a communications install that apparently also had some kind of problem and is under insurance claim. I don't know of the name, but they could well be a good Battery. Apparently over $900 new and they are listed at around the $160'ish mark.If you can't find them, let me know and I will find the link again. Quote Link to post Share on other sites
wheels 543 Posted September 29, 2016 Author Share Posted September 29, 2016 Had to find the link for someone, so may as well post it as well.http://www.trademe.co.nz/business-farming-industry/industrial/generators-power-supply/solar/auction-1171533466.htm Quote Link to post Share on other sites
ScottiE 174 Posted September 29, 2016 Share Posted September 29, 2016 interesting - here's some additional info - does this stack up as a house bat for a boat? http://www.innovative.co.nz/pdf/RA12-150F.pdf also here's someone selling them at a slightly better price than quoted http://www.recell.co.nz/ritar/ra12-150F.html also at 45kg seems a little heavy at 3.33AH/kg compared to say the swindlery Endurant 125Ah = 4.63 AH/kg Quote Link to post Share on other sites
wheels 543 Posted September 29, 2016 Author Share Posted September 29, 2016 Slightly cheaper? 1paulg sent me this link. Interesting type I did not know was being sold in NZ.http://www.trademe.co.nz/Browse/Listing.aspx?id=1170368012 Quote Link to post Share on other sites
1paulg 17 Posted September 29, 2016 Share Posted September 29, 2016 That link I sent Wheels is v interesting -especially for anyone considering putting Solar into their home because it is an affordable solution for a battery system with Lipo4 capabilities but not the cost which at this stage Lipo4 is still too expensive for a home set up . shame about the weight for the marine application tho since you would need a smaller bank it would still save weight overall -just not the same weight saving as Lipo4.

ScottiE 174 Posted September 29, 2016 Share Posted September 29, 2016 sorry - didn't explain that very well - Recell sell them at 498inc. GST whereas the trademe seller reckons they cost $959 elsewhere. Quote Link to post Share on other sites
wheels 543 Posted September 30, 2016 Author Share Posted September 30, 2016 sorry - didn't explain that very well - Recell sell them at 498inc. GST whereas the trademe seller reckons they cost $959 elsewhere. Yep understood your first post. My "slightly cheaper " was because I reckon the difference between 959 and 498 is a tad more than "sightly" Quote Link to post Share on other sites
ScottiE 174 Posted September 30, 2016 Share Posted September 30, 2016 Ah well in that case - sorry - again! (sh*t - it's been a week of contrition!) Quote Link to post Share on other sites
wheels 543 Posted September 30, 2016 Author Share Posted September 30, 2016 There are a couple of big problems with Nicad. Well actually the two problems are intertwined. It's called Memory Effect. NiCad grows crystals within the cell as it discharges. These Crystals are not easy to get rid of and eventually they grow right across the cell and short it out. As the Crystals grow, the Cell capacity diminishes. To get reduce these Crystals the cell must be fully discharged at a slow rate of discharge. And I mean slowly and fully. As flat as you can possible make the battery. And then you have to fully charge again.Similar to NiMh, you need a specific and special to NiCad charger and cell V is 1.2V and will remain at 1.2V till discharged.
