Detling Posted April 26, 2017 Report Share Posted April 26, 2017 I have never seen mono the same physical size as poly usually a lot larger and more expensive. Link to comment Share on other sites More sharing options...

I suspect you may be referring to amorphous rather than monocrystalline. Mono are generally regarded as superior to poly on a like to like basis. Amorphous are far bigger for the same wattage rating, and around twice the price, which somewhat negates any low light advantages. Link to comment Share on other sites More sharing options...
matty40s Posted April 26, 2017 Report Share Posted April 26, 2017 are you after a specific sized panel?? the ones you are looking at are beaten massively by panels just 10 cm wider. Mono if you want the answer with embellishments. 1 minute ago, stegra said: I suspect you may be referring to amorphous rather than monocrystalline.

Its only 630 from rail to mushroom so those panels wont fit anyway! What I am trying to do is keep the panels away from boat working area so no where near centre line....... So what I really have is two spaces one 1900x850 the other 1500x850. Just looking ar getting maximum wattage at minimum cost in that space. Panelsvwired in series as they are at the other end of the boat to the batteries Controller may well beb http://www.ebay.co.uk/itm/182499867061 J Link to comment Share on other sites More sharing options...

The same package is about £170 from most places I've seen it. I'd guess it's actually coming from China or Hong Kong and I would worry, (probably wrongly), that it may be a copy, and/or customs and duty costs?? So I will be equally interested in how it goes Link to comment Share on other sites More sharing options...

Murflynn Posted April 27, 2017 Report Share Posted April 27, 2017 dunno how these Chinese ebay traders get away with selling stuff from their UK warehouse without CE certification (yes I am aware of the Chinese Export CE symbol, before we begin a diatribe about it ). mind you, in many cases it doesn't stop me from buying (gotta stretch the pension as far as possible).

I know that's what it says, but I've bought cheap stuff on ebay with a UK despatch and, 3 weeks later, it's arrived from China or Hong Kong. Never more than a few quid, so no risk involved, but it has made me cynical and wary - Link to comment Share on other sites More sharing options...

sirweste Posted April 27, 2017 Report Share Posted April 27, 2017 So put aside the ridiculously cheap controller and wifi gadget, Matty, you said that there were panels that would significantly beat (with regard W per £) the OPs original selection, what are they!?
