16 from the panel then 0 does not look good. You should have something out of your controller, especially if it's a MPPT. On my controller, which is a MPPT it usually shows something even if only 0.1A sort of thing, right up to twilight. Mine panels have a light activated auto-isolation switch and turn off at sunset so the amps don't reverse flow out of the battery during the night.

 

I got my GoFelx from Beacon Marine in Westyhaven. Not cheap but so far have proven to be tuff and work very well.

 

The Juicy panels are cheaper and so far I've not heard anything bad about them. I haven't been hands on so can't comment on how they feel 'tuffness wise' compared to GoFlex. I'd think they are also worth a suss though. I have a Juicy battery as well as a Juicy 2.5kva Genny and have been happy with them and the service from Jamie at Enertec.

 

Panels are important so suss a specialist for good ones not a supermarket.

 

 

 

Yeah, maybe the auto-isolation bit is a little made up....Na, it's totally made up :)

OK, an update on my Juice panels. They have failed. The edges had delaminated in quite a few spots, and output down by over 1/2. The edges had become uneven - wavy.

Now, if you recall (see post further up), they were velcro'd to the bimini. All around, with 50mm velcro. Despite being only about a year old, Enertec have refused warranty replacement. They say the failure is due to the mounting system (velcro) being all around, and too much movement in the heat by the velcro. I pointed out to them that;

  1. This is a common mounting system
  2. The old Unisolar panels were mounted like this for over 10 years with no issues
  3. They did not say anything about this when I told them they would be mounted this way.
  4. I've bought quite a few of these for my customers, and referred others.

No change, no warranty replacement, just a discount off new ones (a bit less than trade price).

I'm less than happy with that, and will no longer recommend these panels to anyone.

 

However, due to space/shape/fitment ease, I have paid for the replacements (now 145w in the same dimensions as the older 135w), and velcro'd them down with approx 100mm sections, leaving 20mm gaps, all around the panel. This was the recommended method (this time) by Enertec.  

 

Enertec supplied these 2 infra-red images of the panels;

These are supposed to show how the edges were damaged by the velcro. 

 

Here is a pic of the velcro on the new panels;

Be warned, and if you have solar panels mounted with velcro, inspect the edges for deformity. If there is any movement at all, it might pay to modify the mounts. Maybe.

Matt, that sucks they wont pay up for replacements, that's pretty shitty customer service, I was considering these same panels....not now.

The new 145w ones, are the the so called Gen2 ones? Will they replace these if they crap out in 12 months? after all you've mounted them as per their instructions...

I got mine shortly after Matt, on their recommendation used plastic bolts though the fabric. No issues to date.

The old ones were gen2. The new ones are similar (look the same) but use different cells apparently. G3???

I would suggest there wont be a warranty if they can think up a reason.... BUT I have had one panel replaced for a customer without issues.

yep, me too. If I had bought this as a private citizen, I'd be having a go at them under the consumer guarantees act as not fit for purpose.

One year in on Goflex and no issues.  They have been walked on semi regularly, spilt some 'Spray & Walk Away' by mistake, and of course exposed to all weather.  But - it's only a year, and at $400 a pop (I have three 50 watt jobbies) I would hope they last quite a few more.

FWIW, the guy that sold me the Goflex, gave me a scare story about Juice panels at the time...I dismissed it at the time as "of course he would say that about the competitor" - but then maybe IT's results means he wasn't talking total porkies.

Anyway, as I say - one year in on Goflex and all is well so far.

Yep, probably try them next if needed. But they are about 50% more $ than the Juice ones. About 1/2 what a solbian panel is though! $1000 for 135 watts for Goflex...

i looked pretty hard at the juice ones before buying glass panels, glad I didnt by the sounds, and great to hear stories like this in general.

(Before that I tried a cheap chinese flexy panel that was a complete waste of time)
