Thanks for the information James! I had not thought about such issues as wear to seals etc.
I really meet a lot of challenges in this Risør 27-project, but I won't give up yet..

Generally you can, but I would not do it a lot. All the flexing over time could compress the seals that keep the glass water tight to the aluminum frame. I would not put glass or flexible Monocrystalline panels in a high traffic area. I basically only walk on mine when I wash them. And I am barefoot and try and only walk on the white boarders if at all possible.

Thanks for info James.Now when we are looking at these grape panels and the walk-on issue, do you think the rigid Grape panles can be walked on? Theri product sheet (http://www.grapesolar.com/files/5513/1342/8369/GS-S-100-TS_Data_Sheet_Rev-3.pdf) does give info about glas thickness...Bendik2014-06-19 8:53 GMT+02:00 James Sizemore james@deny.org [electricboats] <electricboats@yahoogroups.com>:
If I had to guess I would say your ebay and the Grape panels are all the same Sacred panels. If someone has the Grape panels and could take a picture of the name plate on the back of the panels I could tell you for sure. Your local seller has them marked them up quit a bit (VAT?). I paid much less for mine.
If I was buying my sell now I would buy them from Grape, only because it is a very successful company so should be around long enough to honor the warranty if needed. They sell Grape panels at both Home Depot and Costco here in the US.On Jun 17, 2014, at 2:00 PM, Bendik Vignes bendik.vignes@yahoo.com [electricboats] <electricboats@yahoogroups.com> wrote:Hi James!Do you have any prize suggestions on the sacred solar / grape solar panels? There is a local retailer of the Sacred panels here in Norway, but i find 430 dollars for the 100W flexible panel too expensive for my project...What aobut this one (MX Flex): http://www.ebay.com/itm/261501848394?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT. Any experience with this brand?Regards Bendik2014-06-17 9:28 GMT+02:00 James Sizemore yamez4u@gmail.com [electricboats] <electricboats@yahoogroups.com>:
No it is a simply request for you to supply evidence for an absurd statement:"The majority of PV panels are made in china, these days.The std efficiency these days is around 20%."
I am simply asked you to find a single link to a single Chinese Panel that is 20% efficient that does not use SunPower cells. Who knows you might even be able to find one or two. I am not asking you to prove that the "standard" Chinese panels is 20% efficient. Which is what you claimed.The average US and Japanese panels are not that efficient. Only the very high end of the consumer panels are in that range, with a price premium on them for being the top of the line in efficiency.If there are sooooooo many Chinese 20% efficient panels out there it should only take you a few minutes? Please enlighten the group. Boats have very limited space for panels it would be incredibly useful, to have this list of 20% efficient cheap Chinese panels.I will start the list off with two companies that make panels with SunPower Cells that are 20% efficient and are reasonably priced:
Now your turn you just need to find one panel......One little panel. You CAN DO IT!On Jun 12, 2014, at 1:57 AM, Hannu Venermo gcode.fi@gmail.com [electricboats] <electricboats@yahoogroups.com> wrote:The majority of PV panels are made in china, these days.
