Did i mention i have some new solar panels ( summer 2022 ) . . . . . ?
LENSUN 150w Black Flexible panels. ( LS-150FX2-B2 )
i have two of them . . . so thats 300W as a matched pair.

here they are. . . .

.
these have the 9BB / BusBar cell tech . .
spec:

i got sent the Rubber strip version . . . . . but the strip is just a press fit and not glued on so can be removed if needs be.
this is the pair . . . so 300W as they stand.
manual included. . .
...
size wise they are not much bigger than the standard 100w ish panels . .
...
with this being them laying again the twin Renogy 200w suuitcase setups. . .
a quick plug in test showed 210W with the panels in series ( 300W max ) at the Bluetti Ac200Max. ( I'm happy with that as we don't have optimal conditions)
ill be using these as mobile panels for my various setups,
either laying flat on the floor, or on the van roof with a few magnets.
or possibly on the 45Degree stands i made up last year out of hard board and webbing straps.
+++++++++++++++++++++++++++++++++
now for the back story.
Lensun sent me these panels as warrenty replacements for two 100W failed panels from last year
it went like this . . .
The sun started again for 2022 . . . so i decided to do an inventory of my solar panels and test them on the new Bluetti AC200Max to see which ones worked best with the unit and gave the best charge rate. . .
during testing it was evident that two of the Lensun panels (Ls-100fx2) were dead. - no voltage output.
this is the first time I've had any panel failure . . . and though it odd that out of all the panel i have its two identical panels that have gone . . . . hmm.?
testing showed that the panel was dead untill and extreme bend was placed on the panel, at which point it showed some voltage. .
this lead me to believ that there was eithe cell damage some where . . .
or . .
cell busbar damage.
++++
so i reached out to Lensun as these panels were 13 or 14months old -
they asked for some pics and tests etc to run past their engineers . . . which i happily done for them.
i even sent them a video :

after a few emails they offered to replace them under warrenty - which was nice. ( but i wasnt too sure about getting the same model panels, incase there was a common issue that caused the double failiure.
+++++
separately id also asked for quote for two of the newer 9BB 150w panels, . . . in a quick lightbulb moment i emailed them and asked if i could have the 150w panels as warranty replacements.
they agreed as long as i paid the difference . . . which i did.
so, that's how come we now have these 150w panels.
+++++
here is reminder that solar panels are very delicate and that the faxable and foldable panels must be treated with respect, and not bent or smashed about.
+++++
Lensun didnt want the faulty panels back . . .
so i decided to operate on them . . .
this is the death of a solar panel . . .
these are the pair:
i cut into the rubber top coat to get to the busbars and contacts. . .
here you can see the glass/silicone cell and foil wires . .
.
bending the panel to extrremes you can hear the glass cracking and the effect, you can also see the cell cracks. . .
you can also see these little bumps of the BusBars between the cells . . . .
i think that may be the original fault?
a cracked busbar join . . . that had a poor connection and caused the point to heat up and cause the etfe rubber to bulge.
im not sure . . . . but as you see from the video clip above . . . bending the panel caused some output. . .
so its related to mechanical strain.
all in all its kept my faith with Lensun , to honour the warrenty claim.
and to offer me the upgrade at cost price.
so thanks Lensun.

for anyone else that's interested my contact is Alice from Lensun.

@Dellmassive from T6F sent you - they might offer you a discount.

For everyone else have a look at Renogy . . . . . there solar panels and kits are awesome and consistently provide exceptional panel outputs.
put together with a solar controller and one of there Lifepo4 batteries its a winning combo. . . .
add in the Renogy DC-DC/MPPT controller - and its a ready made Leisure system for your van.
