    BP used to be recognised as the best, technology is changing all the time and its almost impossible to keep up with it. I am always wary of any Chinese products, but you pays your money and takes your chance.

    To give you some idea I bought some BP and Siemens panels second hand several years ago in Morocco. I still have some in the garage at home awaiting a project. I took one of the Siemens out the other week and tested it with the multi meter and it was working fine. I must have had these panels for around 5 years and I dont know how old they were when I bought them. They say that solar panels have a life expectancy of around 10 years. I just wonder if the Chinese ones will perform as well when they get older. Regarding the BP ones, if they are made in India or for that matter Outer Mongolia they will still be made to BP specification and quality control. Something that the Chinese have not quite mastered yet.

    to a certain extent, you get what you pay for but then you can pay too much for a cheap panel

    a decent price today would be £100 for a 100watt panel...many are cheaper but may not be so good

    not so sure about that . they build bmw m,bikes and manufacture merc cars etc .,
    but come on they are selling at 80 quid for an 80w panel we were paying that for seconhand in maroc 8-10 years ago. i bought the bp panels off a mate that imported a few pallet loads they were 150 quid about 3 years ago. they are very cheap today . all the ones i have seen look to be as good if not better than some of the early ones .
    first panel i bought is marked solara hamburg . but also shell solar in the corner of the panel under the glass almost hidden . that was second hand . still works .but even then badge engineering was rife it seems .

    As it says on the bottom of all my posts. Quality is remembered long after the price is forgotten.

    I got a Baird, next day delivery off ebay. I can't fault the build quality and it's performed better than expected on overcast days.

    I think writing Bosch on one guarantees a higher price, not sure about higher performance.

    You can see my 3x100 watt panels by clicking my signature
    They were bought from ebay seller Alfrescobay at £108 each
    They perform superb and have delivered over 18 amps on occassion with mppt regulator :thumb:
    They are not re stocking until they know for certain what taxation will be applied on Chinese panels

    Interesting. You've used end mountings. I used two each side to reduce flex on the long sides.

    Now which one is best ?

    And you have a potential shadow problem with that aerial.

    The aeriel is used VERY rarerly and would not impact on three panels
    The only reason the panels are bracketed so is because two panels were previously fitted but I replaced them with three matched 100's of the same dimensions so I only had to buy two brackets
    There is no flex I don't walk on them :Laughing:

    If I was having a punt at new stock myself just now I would try these

    hi brian i have mine end mounted three side by side . thick ally angle as the mounting all the way across my roof . the first three have been up there about 10 yrs now the second three 3 yrs . . there is a slight drop in power from the first three compared to the newer ones . but i can only compare not having really checked them originally .
    i mounted them front and back so branches couldnt get stuck underneath the panels . remember i do drive in silly places .
    they do seem to be ok . and have once had a boat strapped to them as a roof rack . not recommended though .

    I'm not biased on brackets, I normally make them.
    This is a poor picture of a Neisman I did recently

    Its Biard not Baird. Sorry John, that's screwed your joke. :Blush:


    Not a correction of spelling - just to provide accurate info if someone searches for the name.

    My first attempt was the same as your nearside panel and it did cast a shadow in the afternoon. Maybe your aerial sits a bit lower than mine.

    I do worry about the shock loads as we go over bumps, that's my take on it.
