390 watt panels (1 Viewer)

[Basildog]

Thinking about fitting one of these rather than messing around with several smaller panels.
Has anyone else used one ?

I'd want to see a bit more certified proof of the technology before parting with my wonga.
I don't see how this reflected light actually reflects off the background unless the panel itself is clear/opaque... Which it isn't......the back of the panel is in shade of itself.

Its a big panel over 2x1 metres, do you have space for it, personally I would favour 2 smaller ones as I would worry about such a big expanse of glass getting bounced around but I might be over thinking this.

I can see a problem with the reflected light claim if you look under the panels after a few months there is always dirt and muck thus no white surface to reflect any light even if I does get in there and they claim this works well on cloudy days.

They appear to be quoting 390W without any help from the rear - that's a bonus. If so it's a good price for 390W.

Vans with that amount of free space are very very rare

A typical large van. Not a chance

I'm already suspicious that there could be any reflection under a 10mm air gap. It's sounding like snake oil and the 41V panel voltage looks very high for standard solar controllers

Messing around? or fitting what will fit.

I'm thinking the same but mine has a 40mm gap.... It looks very dark under there even on a bright day.
As you say, snake oil for the unwary.

I watched a factual TV program about the making of a solar panel and It was said that the backing sheet on a regular panel must not be badly scratched or damaged so how can omitting it altogether be a good thing ?

In your world as you see it
In my world definitely it's messing around having to fit several panels rather than Bish Bash Bosh with one panel
There is a good space at the back on our van but not measured yet !
Several panels does have the advantage in that if you get a failure at least it can be bypassed and not lose the whole array.

They are saying that the light does pass through the panels ?
It is LG so hardly some back street suppliers, they have won awards for it apparently.

As said it’s a big bit of glass if the van twists and moves as it drives across a rally field, or vibration driving say on cruise control alone a concrete motor way would it resonate and cause it to crack.

After reading just a few words the words "SNAKE OIL" lit up before my eyes.

I’ve never seen a motorhome with a clear space 2x1 meters so this will be interesting

I bought my solar from Bimble , found them very helpful , and happy to discuss queries. They have been going a fair while , and have a lot of stock , seemed very busy when i collected my stuff .
I have 3x 260w (1700x 1000) panels in series , with 60amp Tracer Mppt . When i fitted new house batteries saw it reach 35amps input as it brought them up to full charge. Highest voltage 102v from panels. ( Not sure of relevance of those readings as not that knowledgeable about solar self taught)

I didn't say it for a laugh as I have some idea of the available space, just measured roughly and it actually fits
Available space is 2140 mm x 1350 mm
I have used house panels on other vans including a Swift kontiki and a Winnebago.
Still not sure if I want to rely on 1 panel .

Mine has - I'm about to fit a single 250W panel.

With panels in series from what i understand one goes , takes down all others, unless you wire up in parallel , which needs multiple mppt controllers. Good quality panels should last a long time , (tens of years) . I know some Bliss Mobiles goes with two equal systems , but that a 1.5kw system feeding Li ion , and its £120,000 for just the demount unit (no vehicle) @Basildog

My three x100 produce as witnessed up to 22.5 amps through my MPPT regulator

SNAKE OIL!!! I’d love to get some of that for my ills,,, how much is it? Lol

Caught here just below full power and been on 5 years now

Are you ready for the regulator yet? I have 16th noted on it.

Beware a nice dollop of seagull shit or autumn leaves can put a big dent in a single panels output

Wheres all the 21 amps going ? are you running a lot of stuff ?

Probably have the inverter running

16th still good - I have a reminder set to remind you. Thanks for the reminder . Seagull shit covers more than panels. I have the results of 5 weeks on the road to prove it.

If you have to ask the price you couldn't afford it
